Whitford 16, flowering specimen, to T. harmandii Planch. He says: “Je ne 
puis separer de T. Harmandii les echantillons suivants des Philippines: 
Luzon central, Manille, Balic-balic, n° 356 [Loher] ; prov. de Bataan, monts 
Mariveles, n° 16 [Whitford].” There is absolutely no doubt but that 
Merrill 3258, October, is identical with, and is the fruiting stage of, 
Whitford 16, April, from the same locality, altitude, and habitat, and that 
Gagnepain was in error in referring the two to different species. 
The Philippine material appears to me to be referable to Tetrastigma 
harmandii Planch., rather than to T. strumarum (Planch.) Gagnep., and 
so far as the specimens are comparable, agrees with Thor el 13 U5 from 
Chochin China, in the herbarium of the Bureau of Science. 
The species is not uncommon in thickets on the low dry hills about 
Manila, and is now occasionally found in cultivation for the purpose of 
covering walls, shading porches, etc. Most of the specimens cited above 
have been determined, and the duplicates distributed, as Tetrastigma lan- 
ceolarium Planch.

This species is well characterized by its papillose branchlets, and is 
apparently closely allied to Tetrastigma ramentaceum Planch., of Cochin 
China, a cotype of which is in the herbarium of the Bureau of Science. 
Although I have seen no extra-Philippine material of Tetrastigma papillo- 
sum, I have no hesitation in reducing to it Cissus suberosa Elmer. Mr. 
Elmer’s species is in all respects a Tetrastigma, not a Cissus, and our 
material agrees perfectly with the descriptions of Blume’s species.
