246 SPECIES BLANCOANAE 
Illustrative specimen from Batangas Province, Luzon, Febru- 
ary, 1915 (Merrill: Species Blancoanae No. 804). 
Cissus simplex Blanco Fl. Filip. (1837) 72 (sp. nov.) =Cissus latifolia 
Blanco op. cit. ed. 2 (1845) 52; ed. 3, 1-(1877) 96, non Lam.=CISSUS 
PYRRHODASYS Mig. 
This species was reduced by Fernandez-Villar to Vitis adnata 
Wall., which is correct as Vitis (Cissus) adnata Wall. has been 
interpreted by many authors. However, it is apparent that 
Vitis adnata Wall., as generally interpreted, is a collective 
species. It seems probable that this rather widely distributed 
Philippine form is really Cissus aristata Blume [C. assamica 
Craib, var. pilosissima Gagnep. in Not. Syst. 1 (1911) 353], and 
Blume’s name is much the older; it is at least the form described 
by Miquel as Cissus pyrrhodasys Miq. 
Illustrative specimen from Antipolo, Rizal Province, Luzon, 
January, 1915 (Merrill: Species Blancoanae No. 797). 
Cissus vesicatoria Blanco Fl. Filip. ed. 2 (1845) 50 (vewicatorus) (sp. 
nov.) ; ed. 3, 1 (1877) 94, t. 318=CISSUS REPENS Lam. 
I have followed Fernandez-Villar in the reduction and can 
give no evidence for or against the correctness of the reference. 
Blanco gives no description whatever, so that his name is a — 
nomen nudum. His entire data consists only of the following: 
“Cissus vexicatorus. Enredadera de cuyas hojas usan los indios 
para causticos.—P. Pirapit angin.” 
Illustrative specimen from Angat, Bulacan Province, Luzon, 
September, 1913 (Merrill: Species Blancoanae No. 334).— 
COLUMELLA Loureiro 
(Cayratia Jussieu) 
Cissus rubescens Blanco Fl. Filip. (1837) 71 (sp. nov.) =Cissus alata (7) 
Blanco op. cit. ed. 2 (1845) 51; ed. 3, 1 (1877) 95, non Jacq.=COLU- 
MELLA GENICULATA (Blume) Merr. (Cissus geniculata nee 
Cayratia geniculata Gagnep.). 
Blanco’s description in general applies to Blume’s species and 
to no other known Philippine form. The illustrative specimens — 
have broad leaflets that cannot be described as “lanceolate” as 
Blanco indicates for his species, but other Philippine material | 
representing apparently the same species has leaflets that ap- | 
proach lanceolate in outline. The fruits are globose, very soft — 
and fleshy, and pale-pink in color.
