Pentacme paucinervis Brandis in Journ. Linn. Soc. Bot. 31 (1895) 73. 
There is no doubt as to the identity of the above two species, and accordingly 
Vidal’s name, being the earlier, is here accepted and transferred to Pentacme. 
The specimens on which Pentacme paucinervis was based (Vidal 79, 1166, 2176) 
are all in flower, no fruit being present, while of the specimens of Shorea contorta 
examined by Brandis (Vidal 987, 2159) the former is with fruit and the latter 
with immature buds, the condition of the latter no doubt accounting for the 
fact that Brandis ,was unable to distinguish in it the floral characters of 
Pentacme ; he states morover that Shorea contorta is anomalous in its floral 
structure. The species is common and widely distributed in the Philippines, 
yielding much of the timber commercially known as Lauan. In addition to the 
five specimens collected by Vidal, cited above, we have also examined the following 
extensive series: Merrill 2772, 2697; For. Bwr. 2970, 3199 Ahern’s collector; 
Bur. Sci. 3258 Ramos; For. Bur. 504, 511, 519, 538, 605 Barnes; Wliitford 293; 
For. Bur. 650, 653, 821, 171/8 Borden.

1168, 1/36 Ahern’s collector: Province of Tayabas, Merrill 2851, 2589: Province 
of Nueva Ecija, Vidal 989. 
Widely distributed in Luzon and rather variable. We are of the opinion that 
the above specimens are referable to Blanco’s species and accordingly his specific 
name is accepted, Vidal’s Shorea polita being here reduced. 
ANISOPTERA Korth. 
Anisoptera thurifera (Blanco) Blume Mus. Bot. 2 (1§52) 42; Brandis in 
Journ. Linn. Soc. Bot. 31 (1895) 44. 
After examining a large series of specimens we have come to the conclusion 
that Anisoptera Vidaliana Brandis is scarcely distinct from Blanco’s species, 
there being no constant characters by which the two can be distinguished. 
The fruit of A. Vidaliana as separated by Brandis lias broader wings than does 
that of A. thurifera, but even this character does not appear to be constant. Two 
other closely related species occur in the Philippines, which may later have to 
be reduced, these being A. tomentosa Brandis, represented also by For. Bur. 
2985 Ahern’s collector, characterized by its leaves being slightly tomentose 
beneath, and A. calophylla Perlc., which differs from typical A. thurifera by 
scarcely more valid characters.
