cm wide, the base most often obscurely auriculate and subpeltate, the 
apex gradually narrowed into an acumen 1 to 2 cm long, 5-piinerved,

PoLiLLO, Bur. Sci. 10260 McGregor (type), Bur. Sci 6859 Rohinson. Very 
distinct from any other Philippine species, and apparently from any of other 
regions, resembling vegetatively M. dementis Merr. and M. cephalophora Jferr., 
but having an entirely different inflorescence; perliaps most closely allied to 
M. motleyi Hook. f.

^ The Polillo collection, 92J,2, 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.

Tlie type locality is Burdeos, on the east coast of Polillo. The species is 
extremely near A. hoissieri A. DC, differing onlv 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.
