description is very short and consists only of the statement 
that the trunk is without spines, the leaves alternate, obliquely 
ovate, 7-nerved, obtusely serrate, that it was from Bonbonon, 
Negros, was there known as dalanta, and that the fruits were 
edible. Inquiries made of local officials in Bonbonon elicited 
the information that the name dalanta was unknown to them. 
My only reason for not definitely reducing the species to Zizyphus 
talanai is that Blanco describes the leaves as 7-nerved, a char- 
acter that applies to no known Philippine representative of 
the genus. 
COLUBRINA Brongniart 
Rhamnus carolinianus Blanco Fl. Filip. (1837) 169; ed. 2 (1845) 119; ed.

Rich. 
Blanco’s species was reduced by Fernandez-Villar, by error, 
to Rhamnus wightii W. & A., a species that does not occur in 
the Philippines. The description, habitat, and the Tagalog name 
cabatiti, given by Blanco, all agree with Colubrina asiatica L. C. 
Rich., which is common and widely distributed along the seashore 
throughout the Philippines.

‘ GOUANIA Linnaeus 
Gouania domingensis Blanco FI. Filip. (1837) 196; ed. 2 (1845) 138 (Go- 
vania); ed. 3, 1 (1877) 248, non Linn.=GOUANIA MICROCARPA 
DG. 
This species is common and widely distributed in the Philip- 
pines at low altitudes. Blanco’s species has been reduced to 
Gouania leptostachya DC. by Fernandez-Villar, but the common 
Luzon form appears to me to be G. microcarpa rather than 
G. leptostachya, a conclusion also reached by Vidal.

CISSUS Linnaeus 
CISSUS QUADRANGULARIS Linn.; Blanco Fl. Filip. (1837) 72; ed. 2 
(1845) 52; ed. 3, 1 (1877) 97. 
The Linnean species was correctly interpreted by Blanco. It 
is of very local occurrence in the Philippines and apparently 
thrives only in those provinces subject to a prolonged dry season. 
It occurs only in the settled areas and is manifestly a purposely 
introduced plant in the Philippines.
