Leyte, Buenavista, near Jaro, Wenzel 709, 851+, April 4, 1914 (flowers), 
and June 5, 1914 (immature fruits), in forests, altitude about 500 meters. 
Trigonopleura has hitherto been a monotypic genus, represented by T. 
malayana Hook. f. from the Malay Peninsula, so that the discovery of a 
second species in the Philippines is of considerable interest. The Philippine 
specimens were first referred to Trigonopleura malayana Hook, f., but as 
they did not agree entirely with the figure and descriptions of Hooker’s 
species, specimens were sent to Kew for comparison with the type. In a 
memorandum supplied by Sir D. Prain, director of the Royal Gardens, 
Kew, September 26, 1914, it is noted that the Philippine plant differs from 
Hooker’s type in the lateral nerves of the leaves diverging from the midrib 
at an angle of 45° or less, the glands of the staminal column oblong-obovoid 
and longer than wide, and the anthers obtuse, with no indication of a 
mucro. In T. malayana Hook. f. the lateral nerves always diverge at a 
wide angle (about 70°), the glands are nearly as broad as long, and the 
anthers are clearly mucronate. The specimens collected by Ramos were 
probably distributed as Casearia sp.

SARCOSTIGMA PH I LI PPI N ENSIS sp. nov. 
Frutex alte scandens inflorescentiis parcissime pubescentibus 
exceptis glaber; foliis oblongis, subcoriaceis, usque ad 13 cm 
longis, in siccitate pallidis, nitidis, apice breviter obscure obtuse 
acuminatis apiculatisque, basi acutis, nervis utrinque circiter 5, 
subtus valde prominentibus, curvato-adscendentibus, utrinque 
subfoveolato-reticulatis ; paniculis axillaribus, laxis, usque ad 40 
cm longis, ramis paucis, inferioribus usque ad 16 cm longis; 
floribus fasciculatis, sessilibus, 2.5 ad 3 mm longis, fasciculis 
distantibus. 
A woody vine reaching a height of 30 m and a diameter of 10 
cm, entirely glabrous except the younger parts of the inflores- 
cence. Branches terete, grayish, sparingly lenticellate, slender. 
Leaves alternate, oblong, subcoriaceous, entire, 8 to 13 cm long, 
2.5 to 4.5 cm wide, pale and shining when dry, of the same color 
on both surfaces, the apex obscurely broadly acuminate and 
usually somewhat apiculate, base acute; lateral nerves about 
5 on each side of the midrib, prominent on the lower surface, 
curved-ascending, obscurely anastomosing, the reticulations 
rather dense, subfoveolate and about equally distinct on both 
surfaces; petioles 2 to 3 cm long. Panicles axillary, lax, up to 
40 cm long, the branches scattered, slender, the lower ones up to 
16 cm in length, the younger parts obscurely appressed-pubes- 
cent. Male flowers sessile, mostly in scattered fascicles, or on 
very young parts of the scattered branches, which are spicately
