Much like this at first sight is a curious plant, Marave 12, from Lipa, Ba- 
tangas, consisting of a woody stem with 4 attached branches : the leaves are op- 
posite, subopposite and probably also alternate, some of the leaves of a pair are 
alike in size and shape with petioles of equal length, in. other cases one leaf is 
as before, but the other is almost sessile and quite different in shape, being ovate 
and cordate instead of oval and rounded, but they are never nearly so reduced 
as in B. blumei, The plant more or less suggests B. malabarica Wedd., which 
Villar reported as common near Manila: we have no Philippine material .of the 
latter.

are only distinguished from those cited under the species by the fact that the 
under surface of mature leaves is either destitute of tomentum or has it in more 
or less isolated patches; so far as these collections go, the leaves are neither 
larger nor longer-petioled : the nature of the plant was not noted. They are 
separately recorded only because of their distinct economic importance: although 
the treatment of specific limits is here deliberately more radical than that of 
Weddell, these five collections would otherwise be placed together without the 
difference being considered even worthy of comment.

Ramos : altitudes 1,200 to 1,600 M. The later collections are excellent matches 
for the type. On an extreme view, this might 1 possibly be included in B. platy- 
phylla, as it remotely resembles B. scabrella Gaudich., there placed by Weddell, 
Hooker, and Wright, but held distinct by Clarke. It is well distinct from it by 
its longer spikes with correspondingly numerous glomerules, by the differently- 
shaped, coriaceous, much more finely and closely serrated leaves. The number of 
veins should be corrected to read from 5 to 8 beyond the nerve, the difference 
being due to the omission of those which connect the nerve with the costa.

Apart from the fact that B. weddelliana Vidal seems to be quite the same 
as B. densifiora Wight & Arn., and that the latter is B. platyphylla var. loochooen- 
sis Wedd., this polymorphic species seems not to have been previously collected 
in the Philippines, and the plants cited do not exactly agree with the descriptions 
of any of the varieties. However, they seem to come between the typical species 
and Weddell’s variety macrostachya, which Hooker 42 by synonymy includes in 
B. platyphylla proper, differing from the type mainly by the smaller glomerules,
