Other Names:-
Albizia saman is a well-known tree, rivalled perhaps only by Lebbeck and Pink Siris among its genus. It is well-attested in many languages and has numerous local names in its native range. Most names that originated in Europe (where the tree hardly grows at all) are some variety of “Rain Tree”. The original name, Saman – known in many languages and used for the specific name – derives from zamang, meaning “Mimosoideae tree” in some Cariban languages of northern Venezuela[5].

The name Rain Tree was coined in tropical India, especially Bengal. Its origin is the moisture that collects on the ground under the tree, largely the honeydew-like discharge of cicadas feeding on the leaves.

In the Caribbean region, it is occasionally called marsave. As an introduced plant on Fiji, it is called vaivai (ni vavalagi), from vaivai “watery” (in allusion to the tree’s “rain”) + vavalagi “foreign”.

Habitat : Native to the Neotropics. Its range extends from Mexico south to Peru and Brazil, but it has been widely introduced to South and Southeast Asia, as well as the Pacific Islands, including Hawaii. . It is often placed in the genus Samanea, which by yet other authors is subsumed in Albizia entirely.

Large umbraculiform tree to as much as 60 m tall, the crown to 80 m broad, covering 1/5 hectare, trunk to 1.5 m DBH, unarmed, with gray rough furrowed bark. Leaves alternate, evergreen, bipinnate, 25–40 cm long, with 2–6 pairs of pinnae, each of which bears 6–16 paired stalkless leaflets, with a glandular dot between each pair. Flower heads clustered near the end of twigs, each cluster on a green hairy stalk 7–10 cm long, with many small tubular pinkish-green flowers, calyx and corolla 5-toothed. The many stamen united to form a tube near their bases, seed pods oblong, flat, arcuate, black, 20–30 cm long, with a raised border, each with several oblong reddish-brown seeds ca one cm long. The leaves fold in rainy weather and in the evening, hence the name Rain Tree and 5 o’clock Tree.Several lineages of this tree are available e.g. with reddish pink and creamish golden colored flowers.

Easily propagated from seeds and cuttings. Young specimens transplant easily.

Chemical Constituents:-
Per 100 g, the green leaf is reported to contain 47.8 g H2O, 10.2 g protein, 2.1 g fat, 22.2 g insoluble carbohydrate, 15.7 g fiber, and 2.0 g ash. On an oven-dry basis, the leaves contain ca 3.2% N. Gohl, 1981 tabulates as follows:   As % of dry matter

Medicinal Uses:
Folk Medicine :
According to Hartwell (1967–1971), the root decoction is used in hot baths for stomach cancer in Venezuela. Rain tree is a folk remedy for colds, diarrhea, headache, intestinal ailments, and stomachache (Duke and Wain, 1981). The alcholic extract of the leaves inhibits Mycobacterium tuberculosis (Perry, 1980). The alkaloid fraction of the leaves is effective on the CNS and PNS. In Colombia, the fruit decoction is used as a CNS-sedative. The leaf infusion is used as a laxative (Garcia-Barriga, 1975). In the West Indies, seeds are chewed for sore throat (Ayensu, 1981).

Other Uses:

With a checkerd nomenclature, under Enterolobium in the Wealth of India, Pithecellobium in Common Trees of Puerto Rico, and Samanea in Woody Plants of Ghana, the rain tree is apparently widely traveled. Perhaps one of its most important uses in Latin America is as a shade tree, especially in parks, pastures, and roadsides. Improved growth, nutritive quality, protein content, and yield have been demonstrated by Axonopus compressus, a tropical forage grass, grown under Samanea. “The benefit by association was presumptively attributed to nitrogen made available in the soil by excretion or decomposition of the leguminous nodules.” (Allen and Allen, 1981). The tree house in Walt Disney’s “Swiss Family Robinson” was built in a rain tree 60 m tall with a canopy 80 m in diameter. Simon Bolivar is said to have encamped his entire liberation army under the “saman de guerra” near Maracay, Venezuela. In Malagasy, it is grown as shade tree for cacao, coffee, patchouly, and vanilla. In Indonesia, it is recommended for nutmeg but not for tea. In Uganda, it is considered good for coffee, bad for tea. According to NAS (1980a), “Grass grows right up to the trunk because this species’ leaflets fold together at night and in wet weather, allowing the rain to fall through.” Like Acacia, Ceratonia, Prosopis, and Tamarindus, this produces copious pods with a sweet pulp, attractive to children and animals alike. Pods can be ground up and converted to fodder or for that matter alcohol as an energy source. A lemon-like beverage can be made from the pulp. The wood is soft, lightweight (spec. grav. 0.44; 720–880 kg/m3) of medium to coarse texture, fairly strong, takes a beautiful finish but is often cross-grained and difficult to work. It is used for furniture, general construction, and interior trim, for boxes and crates, panelling, plywood, and veneer. Central American oxcart wheels are made from cross sections of trunks. It is used for boat building in Hawaii, where it is also famous for making “monkeypod” bowls. Shavings from the wood are used for making hats in the Philippines. The tree yields a gum of inferior quality which could be used as a poor man’s substitute for gum arabic. Like most other mimosaceous trees, this is an important honey plant. Rain tree is one host of the lac insect, which, however, produces a poor quality lac, reddish and rather brittle (C.S.I.R., 1948–1976).

Mimosa (Albizia julibrissin)

Botanical Name : Albizia julibrissin
Family :              Leguminosae
Genus  : Albizia
Synonyms : Acacia julibrissin – (Durazz.)Willd.
Common Name : Mimosa,
Official Name :Silktree
Habitat : W. Asia and E. Asia – Iran to China.  Open sunny ravines, forests and by rivers up to 2100 metres in the Himalayas.Woodland Garden; Canopy; Secondary; Sunny Edge; South Wall By;

A decidious Tree growing to 12m by 10m.
It is hardy to zone 7 and is frost tender. It is in flower from July to August, and the seeds ripen from September to November.
Leaf: 20″ alternate, bipinnately compound leaf; late to leaf out; no fall color , Flower/Fruit: Fragrant, light todeep pink, thread like flowers in summer; 5 to 7″ gray-brown seeds pods.

The flowers are hermaphrodite (have both male and female organs)It can fix Nitrogen.

Mimosa, this naturalized small ornamental tree from China is common in edge habitats, such as along roadsides, beside parking lots, and bordering powerlines. The twice-compound leaves with many fine leaflets and pink powderpuff flowers are very distinctive.

After a late leafing-out, the very fragrant flowers appear in June and continue through the summer, followed by flat bean-like pods. The flowers are favorites of insects, such as this bumblebee, and hummingbirds.

The only similar tree in North Carolina is Albizia kalkora, which is locally naturalized on the Duke University campus, Durham, NC. It has larger leaflets, with fewer pairs of branchlets on the rachis (~6 vs. ~12), and much rougher bark.

The plant prefers light (sandy), medium (loamy) and heavy (clay) soils, requires well-drained soil and can grow in nutritionally poor soil. The plant prefers acid, neutral and basic (alkaline) soils and can grow in very alkaline and saline soils. It cannot grow in the shade. It requires dry or moist soil and can tolerate drought. The plant can tolerates strong winds but not maritime exposure.

Requires a well-drained moisture retentive soil and a very sunny position. Succeeds in dry soils. Highly fertile soils can promote soft sappy growth which is frost tender. Trees tolerate a high pH, saline soils, high winds and drought. They also succeed in poor soils. Trees prefer a more continental climate than Britain and when dormant are hardy to about -20°c in such a zone. They are only hardy to about -10°c in the maritime climate of this country. The young growth in spring, even on mature plants, is frost-tender and so it is best to grow the plants in a position sheltered from the early morning sun. They succeed on a sunny wall at Kew, and also in a more open but sunny sheltered position there, but only really succeed outdoors in the mildest areas of Britain. If killed back to the ground by a severe winter, plants can often resprout from the base. The form ‘Rosea’ is hardier and more compact, succeeding even in the drier parts of Britain if given some protection. Plants are quite tolerant of pruning and can be fan-trained for growing on a wall. Any pruning is best done in late winter or early spring. Often grown as a summer bedding plant. Quite tolerant of being transplanted. Plants often produce suckers. Plants in this genus are notably resistant to honey fungus. 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.

Seed – pre-soak 24 hours in hot water and sow March/April in a greenhouse or sow as soon as it is ripe in a cold frame. Germinates in 2 – 3 months at 19°c. Scarification helps. There are about 11,000 seeds to a pound, about 25 – 33% of which germinate. Prick out the seedlings into individual pots of fairly rich soil when they are large enough to handle and grow them on in the greenhouse for at least their first winter. Plant out in late spring or early summer and consider giving them some protection from the cold for their first winter or two outdoors. Root cuttings, late winter in a greenhouse. Cuttings of half-ripe wood, July/August in a frame. Suckers planted out in late winter.

A hardier and more compact form of the species, it succeeds in the drier parts of the country if given some protection
