Dehaasia is a genus of evergreen or deciduous trees or shrubs belonging to the Laurel family, Lauraceae. It is a botanical genus to 53 species of flowering plants belonging to the family Lauraceae. Distributed from continental Asia, from India to China, and islands from Borneo, New Guinea, Java, and Indonesia. The genus was described by Carl Ludwig Blume and published in Rumphi 1: 161 in 1837. (Jun 1837).[1]
Characteristics
About 35 species in Cambodia, China, Indonesia, Laos, Malaysia, Myanmar, Philippines, Thailand, Vietnam, with the center of diversity in west Malaysia; three species in China, two endemic.[2] Alseodaphne, Dehaasia and Nothaphoebe are, morphologically, three closely related but distinct genera near to the Persea subgroup of the Lauraceae. Shrubs or small hermaphrodite trees, up to 5 m tall. They are bush or trees of medium size.[3] in montane forest, Cloud forest, Laurel forest. The leaves are alternate.[4] The bark is usually whitish to grey, soft, papery, peels easily, with the xylem yellow. Branchlets yellow-white initially but soon grayed, slender, glabrous, warty, lenticellate, with distinctive leaf scars; young ones more or less angled; innovation covered with long and finely appressed hairs. White twigs, thin and stiff, with visible signs of scarring produced by the leaves. The sheet s are grouped at the apex of the twig: The inflorescences in tassels arm, generally thin with many bracts with few flowers, usually upright and branched at right angles. The fruit is black-dark and shiny, generally scarlet but sometimes yellow or green. Usually ovoid, rarely globose with an exocarp fleshy and meaty. The dispersal of seeds is due to birds that swallow them, so the berries are shaped to attract the birds. The fruits are an important food source for some birds.
