Hibiscus diversifolius

[amazon_link asins=’B01NAVGRW6,B012IBJKAO,B01M33YF09′ template=’ProductCarousel’ store=’finmeacur-20′ marketplace=’US’ link_id=’74d1de9a-bfe0-11e7-8782-399cc9a2202a’]

Botanical Name : Hibiscus diversifolius
Family: Malvaceae
Genus: Hibiscus
Species:H. diversifolius
Kingdom:Plantae
Order: Malvales

Common Names: Swamp Hibiscus

Habitat : It occurs in tropical Africa, New Guinea, the Philippines, many Pacific Islands, Central and South America, the Galapagos Islands, New Zealand, Norfolk Island as well as the states of New South Wales and Queensland in Australia. There is disagreement over its native range. Some sources consider it native only to Africa, and naturalised elsewhere; but it is considered a native in New Zealand and Australia

It is found in low, swampy areas; in Africa it may occur inland or near the coast, but in all other continents it occurs only in coastal areas. This distribution, together with genomic evidence, suggests that it originated in Africa, and colonised the other continents through long-range salt-water dispersal.

Description:
Hibiscus diversifolius is a deciduous Shrub. It is a widespread species of hibiscus. It grows to between 1 and 2 metres in height, with prickly stems and yellow flowers with a maroon basal spot during spring summer.

The stems have many short prickles.

The leaves near the ends of the stems can be undivided and the lower leaves can have either three or five lobes, but the lobing is only shallow. The leaf margins are irregularly toothed. The leaf surfaces are rough to touch because of the short, stiff, bristle-like hairs.

The flowers are pale yellow with purple centres.

Flowers are carried in arching terminal sprays and are held facing the ground. Blooms are produced in the warmer months.

The calyx is covered with stiff bristles and the nectary is conspicuous.

The seed pod is also covered with rigid bristly hairs.

It is frost tender. The flowers are hermaphrodite (have both male and female organs) and are pollinated by Insects.The plant is self-fertile.
Cultivation:
Prefers a well-drained humus rich fertile soil in full sun. A frost-tender shrub, it can be grown as an annual in temperate climates where it can flower and set seed in its first year of growth. Plants can also be overwintered in a cold greenhouse if the winter is fairly mild. As the specific name of this plant suggests, the leaves vary widely in shape. The first leaves to be produced are semi-circular in shape, but later leaves are distinctly three-lobed. Plants are self-fertile.

Propagation:
Seed – sow spring in a greenhouse. The seed germinates inside 2 weeks and should be potted up into individual pots as soon as it is large enough to handle. Grow the plants on fast in a fairly rich compost and plant them out in late spring after the last expected frosts. Cuttings of half-ripe wood, July/August in a frame. These will be difficult to overwinter unless kept in heated environment.

Edible Uses:
Young leaf buds – they are good either raw or cooked. The young leaves can also be eaten, they are mild and quite mucilaginous, making a pleasant addition to the salad bowl. Flowers – raw or cooked with other foods. They have a very mild flavour and are very mucilaginous. They make a very acceptable and beautiful addition to the salad bowl. Root – it is edible but very fibrousy[144]. Mucilaginous, without very much flavour.

Medicinal Uses:
Abortifacient.
Known Hazards: Some caution should be observed when using this plant because there is a report that it might be used to procure abortions. No further details are found.

Rhizophora mangle

[amazon_link asins=’B00P72D4FO,B009GD3EGY,B00P728QIY,B018IV26YU,B00NU9FM92,B077QNJHB2,B00CHA2MVQ,B0195NGP88,3848456559′ template=’ProductCarousel’ store=’finmeacur-20′ marketplace=’US’ link_id=’37be4e27-e473-11e7-8d4d-f92338f82170′]

Botanical Name : Rhizophora mangle
Family: Rhizophoraceae
Genus: Rhizophora
Species: R. mangle
Kingdom:Plantae
Order: Malpighiales

Common Name: Red mangrove

Habitat : Red mangroves are found in subtropical and tropical areas in both hemispheres, extending to approximately 28°N to S latitude.(Tropical America from Bermuda through West Indies to Florida. Northern Mexico south to Brazil and Ecuador including Galapagos Islands and north-western Peru. Western Africa from Senegal to Nigeria; Angola, Melanesia, Polynesia (Little, 1983).) They thrive on coastlines in brackish water and in swampy salt marshes. Because they are well adapted to salt water, they thrive where many other plants fail and create their own ecosystems, the mangals. Red mangroves are often found near white mangroves (Laguncularia racemosa), black mangroves (Avicennia germinans), and buttonwood (Conocarpus erectus). Through stabilisation of their surroundings, mangroves create a community for other plants and animals (such as the mangrove crab). Though rooted in soil, mangrove roots are often submerged in water for several hours or on a permanent basis. The roots are usually sunk in a sand or clay base, which allows for some protection from the waves.

Rhizophora mangle grows on aerial prop roots, which arch above the water level, giving stands of this tree the characteristic “mangrove” appearance. It is a valuable plant in Florida, Louisiana, and Texas coastal ecosystems. In its native habitat it is threatened by invasive species such as the Brazilian pepper tree (Schinus terebinthifolius). The red mangrove itself is considered an invasive species in some locations, such as Hawaii, where it forms dense, monospecific thickets. R. mangle thickets, however, provide nesting and hunting habitat for a diverse array of organisms, including fish, birds, and crocodiles.

Description:
Red mangroves are easily distinguishable through their unique prop roots system and viviparous seeds. The prop roots of a red mangrove suspend it over the water, thereby giving it extra support and protection. They also help the tree to combat hypoxia by allowing it a direct intake of oxygen through its root structure.

Tree 5–20(-30) m tall, 20–50(-70) cm in diameter with arching stilt roots 2–4.5 m high. Bark gray or gray-brown, smooth and thin on small trunks, becoming furrowed and thick; inner bark reddish or pinkish. Leaves opposite or elliptical, acute at tip and base, entire, without visible veins, thick, leathery, glabrous, 6–12 cm long, 2.5–6 cm wide, shiny green upper surface, yellow-green, black-dotted underneath. Petiole 1.5–2 cm long. Stipules paired, leaving ring scar. Flowers mostly 2–4 on forked stalk 4–7 cm long in leaf axil, pale yellow, ca 2 cm across. Bell-shaped hypanthium ca 5 mm long with 4 widely spreading, narrow, leathery, pale yellow sepals 12 mm long; petals 4, 1 cm long, curved downward, whitish but turning brown, cottony on inner side; stamens 8, stalkless. Ovary inferior conical, 2-celled with 2 ovules each cell; style slender; stigma 2-lobed. Berry, ovoid, 3 cm long, dark brown. Seed 1, viviparous, becoming cigar-shaped, to 25 cm long and 12 mm in diameter (Little, 1983). They are a darker shade of green on the tops than on the bottoms. The tree produces pale pink flowers in the spring.

Cultivation:
Since natural regeneration is so good, this species is not often cultivated, but it has been planted, for example, to stabilize the banks of brackish aquaculture enclosures. Direct seeding yields ca 90% survival in Rhizophora and Avicennia. Air-layering and the planting of propagules have both been successful in Florida (NAS, 1980a).
Chemical Constituents:
Per 100 g, the leaf is reported to contain, 10.7 g protein, 3.4 g fat, 77.0 g total carbohydrate, 14.5 g fiber, and 8.9 g ash (Duke and Atchley, 1983 in ed). Per 100 g, the leaf meal is reported to contain 5.6 g H2O, 7.5 g protein, 3.6 g fat, 59.3 g NFE, 13.9 g fiber, 10.1 g ash, 1.350 mg Ca, 140 mg P, 15.2 mg Fe, 650 mg K, 600 mg b-carotene equivalent, 88 mg Mg, 30 mg Mn, 3.5 mg Cu, 0.52 mg Co, 4.3 mg Zn, 54 mg I, 13 mg thiamine, 19 mg riboflavin, 240 mg niacin, 32 mg folic acid, 5.3 mg pantothenic acid, and 46.0 mg choline (Morton, 1965). I suspect that the vitamins are off by a magnitude or two. Something is wrong with the amino acid figures as well, but perhaps the proportions are worth repeating, arginine 1.1 : lysine 0.9 : methionine 0.421 cystine 0.301 : glycine 0.801. Another analysis of the leaf tablets shows, per 100 g, 790 mg S, 8.3 mg Cu, 920 mg Na, 8.3 mg B, 224 mg chlorophyll, 0.68 mg folic acid, 5.2 ppm cobalt, and 144 ppm F (Morton, 1965). Fresh leaves contain 65.6% moisture and ca 0.1% chlorophyll. Dry bark contains 10–40% tannin, aerial roots ca 10.5%

Medicinal Uses:
The red bark of the South American mangrove tree has been used for many years by the natives as a febrifuge but more recently it has been claimed that it is a specific in leprosy. They administer a beginning dose of one fluidrachm (3.75 mils) of the fluidextract twice a day which is gradually increased until the patient is taking a fluidounce and a half (45 mils) daily.

Folk Medicine:
Red mangrove is a folk remedy for angina, asthma, backache, boils, ciguatera, convulsions, diarrhea, dysentery, dyspepsia, elephantiasis, enuresis, epistaxis, eye ailments, fever, filariasis, hemoptysis, hemorrhage, inflammation, jaundice, leprosy, lesions, leucorrhea, malignancies, scrofula, short wind, sores, sorethroat, syphilis, tuberculosis, uterorrhagia, and wounds. One Cali doctor reported a cure of throat cancer, with gargles of mangrove bark The bark of the tree is boiled (1 handful of chopped bark in 1 gallon of water for 10 minutes) and used as a hot bath for very stubborn or serious sores, skin conditions, leprosy and swellings.

.
Other Different Uses:
Timber of the mangrove is used for cabinetry, construction, piling, poles, posts, shipbuilding, and wharves. Duke (1972) notes that in Panama it is being studied for its telephone pole potential. In the Choco it is being exploited for the pulp industry. Cattle will eat mangrove leaf meal after CaCO3 has been added to raise the pH. Morton (1965) even describes a wine made from mangrove leaf and raisin.Amerindians ate the starchy interior of the fruit and hypocotyl during hard times (Morton, 1965). Dried hypocotyls have been smoked like cigars. Dried leaves have been used in Florida as a tobacco substitute. African children use the dried fruits as whistles (Irvine, 1961). In Costa Rica, concentrated bark extracts are used to stain floors and furniture, a habit shared with Africa’s Ashantis. Cuna Indians make fishing lines from the brown branches. Although some have speculated that Rhizophora plantings can be used to extend or preserve precarious shores. Hou resurrects a quote suggesting the contrary “mangrove follows the silting up of a coastal area rather than precedes and initiates the accumulation of mud or other soil…it establishes itself merely on accrescent coasts” (Hou, 1958). Morton (1965), however, notes that the American Sugar Company introduced it in 1902 as a soil retainer on the mud flats of Molokai. According to Garcia-Barriga (1975) Kino de Colombia, resin from the red mangrove, has several medicinal uses.

Landscape Uses:Border, Container, Foundation, Seashore, Specimen, Woodland garden. Succeeds in any moderately fertile moisture retentive soil in sun or semi-shade. Grows well in heavy clay soils. A rather greedy plant, it is apt to impoverish the soil. The flowers attract butterflies and moths. The plant also attracts various beneficial insects such as ladybirds, lacewings and hoverflies to the garden, these insects will help to control insect pests in the garden. Special Features: Attractive foliage, North American native, Naturalizing, Suitable for cut flowers, Suitable for dried flowers.

Propagation :
Seed – sow spring in a cold frame. Only just cover the seed and do not allow the compost to become dry. Prick out the seedlings into individual pots when they are large enough to handle, and grow them on for their first winter in pots. Plant them out into their permanent positions in spring or early summer. Division in spring or autumn. Larger divisions can be planted out direct into their permanent positions. We have found it best to pot up the smaller divisions and grow them on in a lightly shaded position in a cold frame, planting them out once they are well established in the summer.

Edible Uses :
Edible Parts: Leaves; Oil; Seed.
Edible Uses: Oil; Tea.

Young leaves and flowering stems – cooked. Seed. Used as a thickener in soups. The seed is very small and is only used as a survival food when all else fails. A tea can be made from the flowers and/or the leaves.
Medicinal Uses :

Antiseptic; Haemostatic; Kidney; Salve; Styptic.

Haemostatic, styptic. The root is applied as a poultice to burns. An infusion of the dried powdered herb can be used as an antiseptic. The blossoms are analgesic, astringent and febrifuge. They have been chewed and the juice slowly swallowed to treat sore throats. A tea made from the flowers is used in the treatment of diarrhoea, body pains, fevers and snakebites. The plant contains quercitin, a compound that is reportedly useful in the treatment of haemorrhagic nephritis. This plant is said to have similar medicinal properties to S. virgaurea. These are:- Goldenrod is a safe and gentle remedy for a number of disorders. In particular, it is a valuable astringent remedy treating wounds and bleeding, whilst it is particularly useful in the treatment of urinary tract disorders, being used both for serious ailments such as nephritis and for more common problems such as cystitis. The plant contains saponins that are antifungal and act specifically against the Candida fungus which is the cause of vaginal and oral thrush. It also contains rutin which is used to treat capillary fragility, and phenolic glycosides which are anti-inflammatory. The leaves and flowering tops are anthelmintic, anti-inflammatory, antiseptic, aromatic, astringent, carminative, diaphoretic, mildly diuretic, febrifuge and stimulant. A good vulnerary herb, it has also proved of value when used internally in the treatment of urinary infections, chronic catarrh, skin diseases, influenza, whooping cough, bladder and kidney stones etc. Due to its mild action, goldenrod is used to treat gastro-enteritis in children. It makes an excellent mouthwash in the treatment of thrush. The plant is gathered in the summer and dried for later use. The seed is anticoagulant, astringent and carminative. A homeopathic remedy is made from the plant. It is used in the treatment of kidney and bladder disorders, rheumatism and arthritis. The German Commission E Monographs, a therapeutic guide to herbal medicine, approve Solidago canadensis for infections of the urinary tract, and kidney and bladder stones .
