Castanopsis inermis
Content
Description
Tree, 10-30 m by 30-90 cm ø;
Leaves (6-) 10-15(-20) by 4-7½ cm (index 2.1-3), widest slightly below to slightly above the middle;
Stipules, if distinct, triangular, 1 mm, caducous.
Fruits 1-4, with dense reddish brown tomentum, 2-3 by 1½-2 cm, completely free from the cupule except for the convex, glabrous, rugose base;
Distribution
Asia-Tropical: Malaya (Peninsular Malaysia present, Singapore present); Sumatera (Sumatera present), Banka present, Lingga Is present, Tapanuli present
Malesia: Sumatra (mostly in the southern part; twice found in Tapanuli), also Banka and Lingga Is., and Malay Peninsula (common; also Singapore).
Notes
Branches spreading. Leaves darkish green. Flowers cream-coloured or the lobes brownish-tipped; stamens white. Fruit when unripe pale bluish green or greyish.
Materials from Burma formerly reckoned here, generally belong under C. lanceaefolia, which differs in the cupule having concentrical rings outside and a single fruit inside.
C. inermis, C. psilophylla from Borneo, and C. philipensis from the Philippines are closely related, C. lucida being more remote. They can best be distinguished by comparison and then will be found to differ in a number of correlating characters, summarized in the key.
Records of this species from Borneo relate to C. psilophylla.
