Common Names: Sugar Maple, Florida Maple, Hard Maple, Rock Maple

Habitat : Acer saccharum is native to the hardwood forests of eastern Canada, from Nova Scotia west through Quebec and southern Ontario to southeastern Manitoba around Lake of the Woods, and the northern parts of the Central and eastern United States, from Minnesota eastward to the highlands of the eastern states. It is found in a variety of soil types, doing best in deep rich well-drained soils from sea level to 1600 metres. Rich usually hilly woods.

Description:
Acer saccharum is a deciduous tree normally reaching heights of 25–35 m (80–115 ft) tall, and exceptionally up to 45 m (148 ft). A 10-year-old tree is typically about 5 m (16 ft) tall. When healthy, the sugar maple can live for over 400 years.

The leaves are deciduous, up to 20 cm (7.9 in) long and equally wide, with five palmate lobes. The basal lobes are relatively small, while the upper lobes are larger and deeply notched. In contrast with the angular notching of the silver maple, however, the notches tend to be rounded at their interior. The fall color is often spectacular, ranging from bright yellow through orange to fluorescent red-orange, although they look best in the northern part of its range. Sugar maples also have a tendency to color unevenly in fall. In some trees, all colors above can be seen at the same time. They also share a tendency with red maples for certain parts of a mature tree to change color weeks ahead of or behind the remainder of the tree. The leaf buds are pointy and brown-colored. The recent year’s growth twigs are green, and turn dark brown.

The flowers are in panicles of five to 10 together, yellow-green and without petals; flowering occurs in early spring after 30–55 growing degree days. The sugar maple will generally begin flowering when it is between 10 and 15 years old. The fruit is a pair of samaras (winged seeds). The seeds are globose, 7–10 mm (9?32–13?32 in) in diameter, the wing 2–3 cm (3?4–1 1?4 in) long. The seeds fall from the tree in autumn, where they must be exposed to 90 days of temperatures below ?18 °C (0 °F) to break their coating down. Germination of A. saccharum is slow, not taking place until the following spring when the soil has warmed and all frost danger is past.

Bloom Color: Green. Main Bloom Time: Early spring, Late spring, Mid spring. Form: Oval, Rounded.

The sugar maple is also often confused with the Norway maple, though they are not closely related within the genus. The sugar maple is most easily identified by clear sap in the leaf petiole (the Norway maple has white sap), brown, sharp-tipped buds (the Norway maple has blunt, green or reddish-purple buds), and shaggy bark on older trees (the Norway maple bark has small grooves). Also, the leaf lobes of the sugar maple have a more triangular shape, in contrast to the squarish lobes of the Norway maple.

Although many people think a red sugar maple leaf is featured on the flag of Canada, the official maple leaf does not belong to any particular maple species; although it perhaps most closely resembles a sugar maple leaf of all the maple species in Canada, the leaf on the flag was specially designed to be as identifiable as possible on a flag waving in the wind without regard to whether it resembled a particular species’ foliage.

The sugar maple is the state tree of the US states of New York, Vermont, West Virginia and Wisconsin.
Cultivation:
Landscape Uses:Firewood, Screen, Specimen, Street tree, Woodland garden. Of easy cultivation, it prefers a good moist well-drained soil but succeeds on most soils, though it is more likely to become chlorotic as a result of iron deficiency on alkaline soils. Grows well in heavy clay soils. Trees need full light and a lot of space. This species is one of the most shade tolerant of the N. American maples. It tolerates atmospheric pollution and so is often used as a street tree, though it can suffer from soil compaction and the use of salt on the roads in frosty weather. Tolerates a pH in the range 4.5 to 7.3. Hardy to about -45°c when fully dormant. A fast-growing tree for its first 40 years in the wild, this species is not a great success in Britain, though it does better than once thought. It grows well in Cornwall. In cultivation it has proved to be slow growing when young. Trees can live for 250 years in the wild. A very ornamental tree but a bad companion plant, inhibiting the growth of nearby plants. This species is commercially exploited in America for its sap. Along with its sub-species it is the major source of maple syrup. There are some named varieties. The sap can be tapped within 10 – 15 years from seed but it does not flow so well in areas with mild winters. Special Features:Attracts birds, North American native, Inconspicuous flowers or blooms.

Propagation:
Seed – best sown as soon as it is ripe in a cold frame, it usually germinates in the following spring. A lot of the seed is non-viable, it is best to cut a few open to see if there is an embryo. An average of 95% germination can be achieved from viable seed. Pre-soak stored seed for 24 hours and then stratify for 2 – 4 months at 1 – 8°c. It can be slow to germinate, sometimes taking two years. The seed can be harvested ‘green’ (when it has fully developed but before it has dried and produced any germination inhibitors) and sown immediately. It should germinate in late winter. If the seed is harvested too soon it will produce very weak plants or no plants at all. When large enough to handle, prick the seedlings out into individual pots and grow them on until they are 20cm or more tall before planting them out in their permanent positions. Layering, which takes about 12 months, is successful with most species in this genus. Cuttings of young shoots in June or July. The cuttings should have 2 – 3 pairs of leaves, plus one pair of buds at the base. Remove a very thin slice of bark at the base of the cutting, rooting is improved if a rooting hormone is used. The rooted cuttings must show new growth during the summer before being potted up otherwise they are unlikely to survive the winter.

Edible Uses:
Edible Parts: Inner bark; Leaves; Sap; Seed.
Edible Uses: Sweetener.

The sap contains quite a large proportion of sugar. This can be used as a refreshing drink, or be concentrated into a syrup by boiling off the water. The syrup is used as a sweetener on many foods. The sap can be harvested in late winter or early spring[, the flow is best on a warm sunny day after a frost. Trees on southern slopes in sandy soils give the best yields. It is best to make a hole about 7cm deep and about 1.3 metres above the ground. Yields of 40 – 100 litres per tree can be obtained. The best sap production comes from cold-winter areas with continental climates. The sap contains 2 – 6% sugar, thus about 32 litres are required to make a litre of maple syrup. Self-sown seedlings, gathered in early spring, are eaten fresh or dried for later use. Seeds – cooked. The wings are removed and the seeds boiled then eaten hot. The seed is about 6mm long and is produced in small clusters. Inner bark – cooked. It is dried, ground into a powder and then used as a thickening in soups etc or mixed with cereals when making bread.
Medicinal Uses:
A tea made from the inner bark is a blood tonic, diuretic and expectorant. It has been used in the treatment of coughs, diarrhoea etc. A compound infusion of the bark has been used as drops in treating blindness. The sap has been used for treating sore eyes. The inner bark has been used as an expectorant and cough remedy. Maple syrup is used in cough syrups and is also said to be a liver tonic and kidney cleanser. The Mohegan use the inner bark as a cough remedy, and the sap as a sweetening agent and to make maple syrup.

Other Uses:
Fuel; Potash; Preservative; Wood.

The leaves are packed around apples, rootcrops etc to help preserve them. Wood – close grained, tough, hard, heavy, strong, not very durable, it takes a high polish, remains smooth under abrasion and has a high shock-resistance. It holds nails well, is fair in gluing, dries easily and shrinks moderately. The wood weighs 43lb per cubic foot. Considered by many to be the most valuable hardwood tree in N. America, the sugar maple is used for a wide range of applications including furniture, flooring, turnery, musical instruments and ship building. Accidental forms with the grain curled and contorted, known as curly maple and bird’s eye maple, are common and are highly prized in cabinet making. The wood is also a very good fuel, giving off a lot of heat and forming very hot embers. The ashes of the wood are rich in alkali and yield large quantities of potash

Pneumothorax

Definition:
A pneumothorax is a collapsed lung. A pneumothorax occurs when air leaks into the space between your lung and chest wall. This air pushes on the outside of your lung and makes it collapse. In most cases, only a portion of the lung collapses..

It is the collection of air or gas in the space inside the chest around the lungs, which leads to a lung collapse.

Normally, the pressure in the lungs is greater than the pressure in the pleural space surrounding the lungs. However, if air enters the pleural space, the pressure in the pleura then becomes greater than the pressure in the lungs, causing the lung to collapse partially or completely. Pneumothorax can be either spontaneous or due to trauma.

CLICK & SEE THE PICTURES

If a pneumothorax occurs suddenly or for no known reason, it is called a spontaneous pneumothorax. This condition most often strikes tall, thin men between the ages of 20 to 40. In addition, people with lung disorders, such as emphysema, cystic fibrosis, and tuberculosis, are at higher risk for spontaneous pneumothorax. Traumatic pneumothorax is the result of accident or injury due to medical procedures performed to the chest cavity, such as thoracentesis or mechanical ventilation. Tension pneumothorax is a serious and potentially life-threatening condition that may be caused by traumatic injury, chronic lung disease, or as a complication of a medical procedure. In this type of pneumothorax, air enters the chest cavity, but cannot escape. This greatly increased pressure in the pleural space causes the lung to collapse completely, compresses the heart, and pushes the heart and associated blood vessels toward the unaffected side.
Symptoms:
The symptoms of pneumothrax depend on how much air enters the chest, how much the lung collapses, and the extent of lung disease.

The main symptoms of a pneumothorax are sudden chest pain and shortness of breath. But these symptoms can be caused by a variety of health problems, and some can be life-threatening. If your chest pain is severe or breathing becomes increasingly difficult, get immediate emergency care.
Symptoms include the following, according to the cause of the pneumothorax:

*Spontaneous pneumothorax. Simple spontaneous pneumothorax is caused by a rupture of a small air sac or fluid-filled sac in the lung. It may be related to activity in otherwise healthy people or may occur during scuba diving or flying at high altitudes. Complicated spontaneous pneumothorax, also generally caused by rupture of a small sac in the lung, occurs in people with lung diseases. The symptoms of complicated spontaneous pneumothorax tend to be worse than those of simple pneumothorax, due to the underlying lung disease. Spontaneous pneumothorax is characterized by dull, sharp, or stabbing chest pain that begins suddenly and becomes worse with deep breathing or coughing. Other symptoms are shortness of breath, rapid breathing, abnormal breathing movement (that is, little chest wall movement when breathing), and cough.

*Tension pneumothorax. Following trauma, air may enter the chest cavity. A penetrating chest wound allows outside air to enter the chest, causing the lung to collapse. Certain medical procedures performed in the chest cavity, such as thoracentesis, also may cause a lung to collapse. Tension pneumothorax may be the immediate result of an injury; the delayed complication of a hidden injury, such as a fractured rib, that punctures the lung; or the result of lung damage from asthma, chronic bronchitis, or emphysema. Symptoms of tension pneumothorax tend to be severe with sudden onset. There is marked anxiety, distended neck veins, weak pulse, decreased breath sounds on the affected side, and a shift of the mediastinum to the opposite side.

Risk factors:

Risk factors for a pneumothorax include the following:

In general, men are far more likely to have a pneumothorax than are women.

1)Smoking. The risk increases with the length of time and the number of cigarettes smoked, even without emphysema.

2)Age. The type of pneumothorax caused by ruptured air blisters is most likely to occur in people between 20 and 40 years old, especially if the person is a very tall and underweight.

3)Genetics. Certain types of pneumothorax appear to run in families.

4)Lung disease. Having an underlying lung disease — especially chronic obstructive pulmonary disease (COPD) — makes a collapsed lung more likely.

5)Mechanical ventilation. People who need mechanical ventilation to assist their breathing are at higher risk of pneumothorax.
Previous pneumothorax. Anyone who has had one pneumothorax is at increased risk of another, usually within one to two years of the first.

Complications:
Many people who have had one pneumothorax can have another, usually within one to two years of the first. Air may sometimes continue to leak if the opening in the lung won’t close. Surgery may eventually be needed to close the air leak.

Diagnosis:
To diagnose pneumothorax, it is necessary for the health care provider to listen to the chest (auscultation) during a physical examination. By using a stethoscope, the physician may note that one part of the chest does not transmit the normal sounds of breathing. A chest x ray will show the air pocket and the collapsed lung. An electrocardiogram (ECG) will be performed to record the electrical impulses that control the heart’s activity. Blood samples may be taken to check for the level of arterial blood gases.

Treatment:
A small pneumothorax may resolve on its own, but most require medical treatment. The object of treatment is to remove air from the chest and allow the lung to re-expand. This is done by inserting a needle and syringe (if the pneumothorax is small) or chest tube through the chest wall. This allows the air to escape without allowing any air back in. The lung will then re-expand itself within a few days. Surgery may be needed for repeat occurrences.

Regular doing Yoga with meditation  under the guideline of some expert will  cure  pneumothorax totally.

5)  5 Top Home Remedies For Pneumothorax

Prognosis:
Most people recover fully from spontaneous pneumothorax. Up to half of patients with spontaneous pneumothorax experience recurrence. Recovery from a collapsed lung generally takes one to two weeks. Tension pneumothorax can cause death rapidly due to inadequate heart output or insufficient blood oxygen (hypoxemia), and must be treated as a medical emergency.

Prevention:
Preventive measures for a non-injury related pneumothorax include stopping smoking and seeking medical attention for respiratory problems. If the pneumothorax occurs in both lungs or more than once in the same lung, surgery may be needed to prevent it from occurring again.

Astragalus canadensis

[amazon_link asins=’B01K3HQMZG,B01K3IVBTW,B00CDK3XHM,B01N13H8B3,B00CDK3Z0W,B00HMGDSYA,B00HMGDSYA,B00NGVZX5C,B00RA31TWI,B00PJ8AXZ0,B00PJ8AXZ0′ template=’ProductCarousel’ store=’finmeacur-20′ marketplace=’US’ link_id=’60df0eb8-01c7-11e7-94b1-b18b488e8fd2′]

Botanical Name: Astragalus canadensis
Family: Fabaceae
Genus: Astragalus
Species: A. canadensis
Kingdom: Plantae
Order: Fabales

Synonyms: Astragalus carolinianus. L.
Common Names : Canadian Milkvetch, Shorttooth Canadian milkvetch, Morton’s Canadian milkvetch
Habitat: Astragalus canadensis is native to Central and eastern N. America – Quebec to Saskatchewan, New York, Louisiana, Nebraska and Utah. IIt grows on shores and rich thickets. Rocky and sandy thickets in Texas.

Description:
Astragalus canadensis is a perennial herb growing to 1 m (3ft 3in). It sends out several thin, erect, green stems, bearing leaves that are actually made up of pairs of leaflets, each leaflet up to 3 centimeters in length. It has inflorescences of tubular, greenish-white flowers which yield beanlike fruits within pods that rattle when dry.

Pagoda-like towers of creamy yellow flowers rise above the dark green leaves in mid-summer, followed by scepters of bead-like seed pods in August. This striking member of the Pea family is an important food for birds, as it retains its seed late into the fall and early winter.

CLICK & SEE THE PICTURES

The flowers are hermaphrodite (have both male and female organs) and are pollinated by Bees, lepidoptera.It can fix Nitrogen.
Suitable for: light (sandy) and medium (loamy) soils and prefers well-drained soil. Suitable pH: acid, neutral and basic (alkaline) soils. It cannot grow in the shade. It prefers dry soil.

Cultivation:
Requires a dry well-drained soil in a sunny position. This species is not hardy in the colder areas of the country, it tolerates temperatures down to between -5 and -10°c. Plants are intolerant of root disturbance and are best planted in their final positions whilst still small. This species has a symbiotic relationship with certain soil bacteria, these bacteria form nodules on the roots and fix atmospheric nitrogen. Some of this nitrogen is utilized by the growing plant but some can also be used by other plants growing nearby. Many members of this genus can be difficult to grow, this may be due partly to a lack of their specific bacterial associations in the soil.

Propagation:
Seed – best sown as soon as it is ripe in a cold frame. A period of cold stratification may help stored seed to germinate. Stored seed, and perhaps also fresh seed, should be pre-soaked for 24 hours in hot water before sowing – but make sure that you do not cook the seed. Any seed that does not swell should be carefully pricked with a needle, taking care not to damage the embryo, and re-soaked for a further 24 hours. Germination can be slow and erratic but is usually within 4 – 9 weeks or more at 13°c if the seed is treated or sown fresh. As soon as it is large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for their first winter, planting them out into their permanent positions in late spring or early summer, after the last expected frosts.

Edible Uses:

Root – raw or boiled. They were often used in a broth. The roots are gathered in spring or autumn. Some caution is advised, if the root is bitter it could be due to the presence of toxic alkaloids.
Medicinal Uses:
The root is analgesic and antihaemorrhagic. It can be chewed or used as a tea to treat chest and back pains, coughs and the spitting up of blood. A decoction of the root is used as a febrifuge for children. A poultice made from the chewed root has been used to treat cuts

Known Hazards: Many members of this genus contain toxic glycosides. All species with edible seedpods can be distinguished by their fleshy round or oval seedpod that looks somewhat like a greengage. A number of species can also accumulate toxic levels of selenium when grown in soils that are relatively rich in that element.

Botanical Name: Picea mariana
Family: Pinaceae
Genus: Picea
Species: P. mariana
Kingdom: Plantae
Division: Pinophyta
Class: Pinopsida
Order: Pinales

Synonyms: P. nigra. Abies mariana. Pinus nigra.

Common Names: Black Spruce, Swamp Spruce

Habitat :Picea mariana is native to Northern N. America – Alaska to Newfoundland and south to British Columbia and W. Virginia. It grows on the cool slopes and bogs. Found on well-drained soils in the north of its range and swamps in the south.Found on a variety of soil types, it grows best in those that are moist and acidic.
Description:
Picea mariana is a slow-growing, small upright evergreen coniferous tree (rarely a shrub), having a straight trunk with little taper, a scruffy habit, and a narrow, pointed crown of short, compact, drooping branches with upturned tips. Through much of its range it averages 5–15 m (15–50 ft) tall with a trunk 15–50 cm (6–20 in) diameter at maturity, though occasional specimens can reach 30 m (98 ft) tall and 60 cm (24 in) diameter. The bark is thin, scaly, and grayish brown. It is in leaf 12-Jan, and the seeds ripen from Oct to November. The leaves are needle-like, 6–15 mm (1/4–9/16 in) long, stiff, four-sided, dark bluish green on the upper sides, paler glaucous green below. The cones are the smallest of all of the spruces, 1.5–4 cm (1/2–1 1/2 in) long and 1–2 cm (1/2–3/4 in) broad, spindle-shaped to nearly round, dark purple ripening red-brown, produced in dense clusters in the upper crown, opening at maturity but persisting for several years. Main Bloom Time: Early spring, Late spring, Mid spring. Form: Pyramidal.

CLICK & SEE THE PICTURES
The flowers are monoecious (individual flowers are either male or female, but both sexes can be found on the same plant) and are pollinated by Wind.Suitable for: light (sandy), medium (loamy) and heavy (clay) soils. Suitable pH: acid and neutral soils and can grow in very acid soils.
It cannot grow in the shade. It prefers moist or wet soil. The plant can tolerates strong winds but not maritime exposure.
It cannot tolerate atmospheric pollution.
Cultivation:
Tolerates poor peaty soils. Succeeds in wet cold and shallow soils but is not very wind-firm in shallow soils. Prefers a pH between 4 to 6 and dislikes shallow chalky soils. Dislikes shade. Intolerant of atmospheric pollution. Resists wind exposure. This tree is one of the most widespread and abundant species in N. America where it is extensively utilized as a timber tree. A short lived and slow growing tree both in the wild and in cultivation. New growth takes place from early May to the end of June and rarely exceeds 60 cm even when young and is less as the tree grows old. Trees have been planted experimentally as a timber crop in N. Europe (this appears to contradict the previous statement that the tree is slow growing. The reason is probably that it is either planted in areas too harsh for most trees to grow or it is only slow growing in milder areas such as Britain). A prolific seed-producer, usually beginning to bear cones at around 10 years of age. In some upland areas, especially over granitic or other base-poor soils, growth rate and health have been seriously affected by aluminium poisoning induced by acid rain. Closely related to P. rubens. Plants are strongly outbreeding, self-fertilized seed usually grows poorly. They hybridize freely with other members of this genus. Trees should be planted into their permanent positions when they are quite small, between 30 and 90cm. Larger trees will check badly and hardly put on any growth for several years. This also badly affects root development and wind resistance. Lower branches often self-layer and form a ring of stems around the parent plant. There are some named forms, selected for their ornamental value. The crushed foliage has a strong scent of balsam or lemon balm. Special Features: North American native, Inconspicuous flowers or blooms.

Propagation:
Seed – stratification will probably improve germination so sow fresh seed in the autumn in a cold frame if possible. Sow stored seed as early in the year as possible in a cold frame. A position in light shade is probably best. Seed should not be allowed to dry out and should be stored in a cool place. Prick out the seedlings into individual pots when they are large enough to handle and grow them on in the greenhouse or cold frame for their first winter. They can be planted out into their permanent positions in early summer of the following year, or be placed in an outdoor nursery bed for a year or so to increase in size. They might need protection from spring frosts. Cuttings of semi-ripe terminal shoots, 5 – 8cm long, August in a frame. Protect from frost. Forms roots in the spring. Cuttings of mature terminal shoots, 5 – 10cm long, September/October in a cold frame. Takes 12 months. Cuttings of soft to semi-ripe wood, early summer in a frame. Slow but sure. Layering. Lower branches often layer naturally in the wild.
Edible Uses:
Edible Parts: Flowers; Inner bark; Seed; Seedpod.

Young male catkins – raw or cooked. Used as a flavouring. Immature female cones – cooked. The central portion, when roasted, is sweet and syrupy. The cones are 1 – 4cm in diameter. Inner bark – cooked. It is usually harvested in the spring and can be dried, ground into a powder and then used as a thickener in soups etc or added to cereals when making bread. An emergency food, it is only used when all else fails. Seed – raw. The seed is about 2 – 4mm long and is too small and fiddly to be worthwhile unless you are desperate. A refreshing tea, rich in vitamin C, can be made from the young shoot tips. A tea is also made from the needles and the bark. A gum obtained from the bark is collected in considerable quantities and used for chewing. Hardened blobs make an excellent chewing gum. It should be aged for 3 days or more before using it. The best gum is obtained from the southern side of the tree. Another report says that the gum, called ‘spruce gum’, is a resinous exudation collected from the branches. A source of ‘spruce oil’, used commercially for flavouring. The young twigs are boiled with molasses, sugar etc and then fermented to produce ‘Spruce beer’. The beer is ready to drink in a week and is considered to be a good source of minerals and vitamins.
Medicinal Uses:
A poultice of the inner bark has been applied to inflammations. A tea made from the inner bark is a folk remedy for kidney stones, stomach problems and rheumatism. An infusion of the roots and bark has been used in the treatment of stomach pains, trembling and fits. A resin from the trunk is used as a poultice and salve on sores to promote healing. The resin can be mixed with oil and used as a dressing on purulent wounds, bad burns, skin rashes, scabies and persistent scabs. The resin can be chewed as an aid to digestion.
