Elaeocarpus lanceifolius is a tree species in the family Elaeocarpaceae. It is found across tropical Asia from Thailand to Yunnan to Nepal to Karnataka, India. It is used for its wood (construction, firewood, charcoal), fruit (food and medicine), and nuts (jewellery, rosaries).

Description

A tall evergreen tree up to 20m tall with gray-black bark and a dense crown.[3][4][5] Some of its distinctive features[3] are: glabrous branchlets; cuneate, more-or-less decurrent leaf bases; and leaves possessing 7 or 8 lateral veins per side with veinlets sparse. Flowers bisexual, white, with a 3-4 x 2-2.5 cm ovoid green drupe that has an inconspicuous exocarp and a bony, conspiculously verrucose endocarp, 1-loculed. The seeds are around 2 cm. It flowers from June to July and fruits from July to September in China. April to June is the flowering season in India, with fruit appearing July to September.

The plant is found in: Thailand; Cambodia; Vietnam; China (northwest Yunnan); Laos; Myanmar; East Himalaya; India (Manipur, Nagaland, Assam, Arunachal Pradesh, Meghalaya, Sikkim, West Bengal, Andhra Pradesh, Karnataka); Bangladesh; Bhutan, and eastern Nepal.[2][3][5]

Habitat

In Cambodia, Laos and Vietnam it is found in secondary or flooded forests.[6] On the Bokor Plateau of Preah Monivong Bokor National Park, Cambodia, the plant is found in sclerophyllous stunted forest on rocky sandy soil near the Bokor Hill Station at the top of the plateau, around 1055m.[7] The tree occurs in Yunnan at altitudes of 2300-2600m.[3] In the Himalayas it grows at elevations up to 2000m, while in Nepal it occurs in open areas between 1000 and 1800m.[4] Moist evergreen forests between 1000 and 2600m are the habitats in India.[5] Amonst the edible trees of the Neora Valley National Park, West Bengal, it is a frequently-found taxa.[8]

Vernacular Names

Common names of Elaeocarpus lanceifolius include: srakûm kach', rumdé:nh tük (Khmer);[6] côm bộng (côm = Elaeocarpus), côm lá thon, côm lá đào (Vietnamese);[9] 披针叶杜英, pi zhen ye du ying (Standard Chinese);[3] badrayo (West Bengal).[8]
