Rain tree (Albizia saman)

Trembesi or Ki Hujan or monkey pod tree or rain tree or Samanea saman (Albizia saman) are species in Fabaceae, grow as large trees, tall, umbrella canopies and are very wide, flowering and bearing fruit, roots absorb a lot of water, popular as a shade and scattered throughout the tropics.

A. saman grows 30-40 m, stem diameter is 4.5 m and tree crowns can be 40-60 m wide. Tree trunks are sometimes bent, narrowed or bulging. The bark is grayish brown and smooth when young, but tanned, very rough and peeling when old.

Dlium Rain tree or monkey pod tree (Albizia saman)

The leaves are compound, pinnate bones, flat edges, elongated round shape, 2-6 cm long, 1-4 cm wide, dark green, slippery surface, the bottom has velvety, soft and 7-15 cm long stems. Light sensitive leaves that will close when it rains and at night where the tree is also called the "Tree at 5 pm".

White flowers and pink patches on the upper hair, up to 10 cm long from the base to the ends of the hair. Crown tube measuring 3.7 cm and 20-30 stamens which have a length of 3-5 cm. Nectar to attract insects to encourage pollination. Hundreds of flowers develop simultaneously filling the canopy.

Straight pods slightly curved, hard skin, 10-20 cm long, 1.5-2 cm wide and 0.6 cm thick. The fruit is blackish brown when ripe. Seeds number 5-25 items, length 1.3 cm, ellipsoid, flat, fat embedded in a reddish brown rag, very sticky and sweet.

The striking characteristic of a monkey pod tree is that branches form an umbrella that grows wider than height. A trembesi tree absorbs 28.5 tons of CO2 per year while other tree species only 1 ton of CO2 in 20 years. This tree also decreases gas concentration without greening and absorbs strong groundwater.

Rain tree grow quickly and are spread in the tropics with an average rainfall of 600-3000 mm / year, altitude 0-500 meters, various types of soil with a pH of 4.7 to 8.5 and able to survive 4 months without rain with a temperature of 20 -38C.

Tree trunks are used for building construction materials and leaves are extracted to treat skin diseases. Litter to reduce aluminum concentration, increase pH and absorb nitrogen content for the soil. Seeds are used as a laxative and are processed into nuts.

Ki Hujan Cultivation uses seeds soaked in water at 80C for 1-2 minutes and dried. Then immersed in water at a temperature of 30-40C for 24 hours to accelerate germination up to 90-100%. Sprouts ready for planting have a length of 20-30 cm.

Source of carbohydrates in the tropics in times of famine. The initial stage forms a white fleshy rhizome, 25 mm long and in chains. Some of the rhizomes grow upright above the ground, then form a tuber-like structure from which new shoots and roots grow, new roots and new rhizomes grow. Other rhizomes grow horizontally or down...
