papyraceous wings: leaves with petioles 2.5 to 5 cm long, the lamina 
chartaceous, lanceolate or broadly lanceolate, 15 to 24 cm long, 5 to 9 
cm wide, the base most often obscurely auriculate and subpeltate, the 
apex gradually narrowed into an acumen 1 to 2 cm long, 5-plinerved, 
all other venation very obscure, upper surface olivaceous, the under

distinct from any other Philippine species, and apparently from any of other 
regions, resembling vegetatively M. dementis Merr. and M. cephalophora Merr., 
but having an entirely different inflorescence ; perhaps most closely allied to 
M. motleyi Hook. f.

The Polillo collection, 9242, somewhat closely matched by Whitford 815, from 
Tingnoan River, Tayabas, has distinctly wider leaves than the type, from Min- ' 
danao, but shows no other important difference.

The type locality is Burdeos, on the east coast of Polillo. The species is 
extremely near A. boissieri A. DC., differing only by having the sepals or some 
of them emarginate. Trivial as the character seems, it holds for 9292, collected 
on the opposite coast of the island from Burdeos, the only other provinces whence 
the form is known being Tayabas and Union.

Represented by 6834; other distribution Tayabas, a very similar species with 
broader leaves ranging from Benguet to Cagayan.
