Geographical Distributions

M. champaca probably originated in India, where it is still planted in the grounds of Hindu and Jain temples, and is distributed from India to south-western China, Indo-China, Peninsular Malaysia, Sumatra, Java and the Lesser Sunda Islands. It is now commonly cultivated throughout the tropics.

Description

This is a huge forest tree, up to 50 m tall and 1.8 m in trunk diametre, with hairless twigs.

Leaves are spirally-arranged with stipules up to 3(-6.5) cm long, united to the hairy stalk for at least one third of their length. The stalk is 1-4 cm long, hairy, bearing a long scale-like scar. The blade is ovate-Iance-shaped to oblong-Iance-shaped size 10-30 cm x 4-10 cm. The base is rounded to triangular-at­tenuate while apex is with acumen, 1-2.5 cm long. It is hairy on its underside, especially on the midrib and veins. Brachyblast is 0.5-2.5 cm long, with 2(-3) nodes and densely hairy. The hairy stalk is 0-2 cm long. The bracts are enclosing the flower cluster, hairy, covering the spindle-like, 3-4 cm long flower buds.

Flowers are fragrant, light yellow when young, turning dark orange in maturity. The segment of floral leaves are (12-)15(-20), in several inconspicuous whorls, reverse egg-shaped size 2-4.5 cm long, thin and semi-transparent. The stamens are 6-8 mm long and its connective appendage is 1 mm long. Their fruits are about 30 in a cluster, each with a 3 mm long and densely hairy stalk.

Fruiting (follicles) is free, basally united to the axis or shortly stalked, 3-20 laxly that are arranged in a 6-9 cm long cluster. Fruit is flat­tened ovoid to slightly spherical size 1.5-3.5 cm x 1-2.5 cm, partially woody, pale brown with white warts con­taining 2-6 seeds.

Seed is ovoid and red-brown and in open fruit it is hanging on little thin cord that is attached to the placenta.

Ecology / Cultivation

M. champaca occurs in humid tropical evergreen forest or at the edge of forest on deep fertile soils at 250-1500 m altitude. Mean maximum temperature of the hottest month ranges from 35-40oC, the mean minimum temperature of the coldest month from 3-10oC.
