In general this species resembles, and is manifesty allied to, 
Trichosporum truncatum Elm. and T. bakeri Merr. ; but the 
calyx is half as long as in the latter, while it differs from the 
former in several characters.

A small glabrous tree, about 5 m high, the branchlets about 
6 mm in diameter, marked with large petiolar scars. Leaves 
thickly coriaceous, broadly elliptic-ovate, brownish-olivaceous

Infructescences axillary, peduncled, up to 10 cm long, dichoto-

A species apparently belonging in the group with Timonius 
obovatus Elm. but with very differently shaped, much larger 
leaves.
