Taxonomy

1 The limits of this species in relation to L. anceps are not entirely clear because most of the available flowering material is rather poor. Further work is necessary. 2 I have placed L. subavenis in the list of insufficiently known taxa as a type cannot be found and the description given by Boerlage is not diagnostic enough to be certain of its identity. Leeuwenberg placed it in synonymy of L. anceps but from the number of secondary veins given in the description it would appear more likely to belong here.

Uses

Previously exploited for a high quality rubber before the widespread use of Hevea brasiliensis.
