SERTULUM BONTOCENSE. 
87 
sessile, distinctly but shallowly 4-lobed. Staminodes slender, 
spatulate, 1 to 1.2 mm long. Male flowers similar to the female 
ones in size. Filaments 1.5 mm long; anthers broadly ovoid or 
ellipsoid, 0.6 mm long. Disk prominent. Fruit oblong-obovoid, 
red, turning dark-purple or black, the pericarp more or less 
fleshy when fresh, apparently thin. Seeds solitary, with a 
shallow longitudinal groove along each side, obscurely sulcate, 
the albumen ruminate. 
Type specimen R. S. Williams 1025, Antamok, Benguet Subprovince, 
Luzon, October 22, 1904, -with $ flowers, altitude about 1,000 m. 
This species is common and widely distributed in the Philippines, and 
most of the material below referred to it has been determined here as 
Tetrastigma lanceolarium Planch., a few specimens as T. angustifolium 
Planch., and very recently a number have been referred to Tetrastigma 
loheri Gagnep., the latter determinations being based on a specimen of 
Whitford 19, referred by Gagnepain to his species.® However, Whitford’s 
specimen is with fruit only, and its determination as Tetrastigma loheri 
Gagnep., must have been based on strong vegetative resemblances between 
it and the type of the species, Loher 371. According to Gagnepain’s de- 
scription, and according to the characters used by him in his key to the 
Asiatic species,* all the material cited below must belong to a different 
species than T. loheri, for that species has glabrous petals, while all our 
material of T. philippinense has pubescent petals. As to Whitford 19 it 
is impossible to say whether or not the petals were glabrous or pubescent, 
but abundant material from the same locality in flower, which matches 
it in all respects, so far as the material in different stages is comparable, 
has pubescent petals. I have no hesitation in referring to Tetrastigma 
philippinense the following material :
