316 SPECIES BLANCOANAE 
by Fernandez-Villar to Sarcolobus carinatus Wall., a species not 
known from the Philippines. Sarcolobus peregrinus Schltr. was 
not based on Blanco’s description, but on actual specimens, with 
the statement: “This plant is evidently identical with Asclepias 
peregrina Blanco, therefore I have chosen the same specific 
name.”” There is no doubt whatever that Asclepias peregrina 
Blanco is identical with Sarcolobus peregrinus Schltr. The 
fruits are hard, smooth, mottled with dark- and light-green, 
and in size and shape strongly resemble those of Heritiera 
litoralis Dry.

TYLOPHORA R. Brown 
Cynanchum tenellum Blanco Fl. Filip. (1837) 204; ed. 2 (1845) 148; ed. 
3, 1 (1877) 258, non Linn. f., nec Riedel=TYLOPHORA PERROT- 
TETIANA Dene. 
Oxystelma bifidum Llanos Frag. Pl. Filip. (1851) 64 (sp. nov); F.-Vill. 
& Naves in Blanco Fl. Filip. ed. 8, 4‘ (1880) 48=? TYLOPHORA 
PERROTTETIANA Dene. (Tylophora bifida F.-Vill.). 
Cynanchum tenellum was reduced by Fernandez-Villar to the 
Philippine Tylophora perrottetiana Dene., but whether or not 
T. perrottetiana Dene. is distinct from T. merrillii Schltr., the 
form that Blanco described is certainly the latter. The species 
is not uncommon in and about Manila, and is the only one of 
the genus to be found in the vicinity of the city. Blanco’s de- 
scription, although very short and imperfect, applies to T. mer- 
rilii Schlitr., which I consider to be the same as Tylophora 
perrottetiana Dene., better than to any other known Philippine 
species of the entire family Asclepiadaceae. Llanos’s descrip- 
tion of Oxystelma bifidum is very poor. Fernandez-Villar trans- 
ferred it to Tylophora as a valid species. If a Tylophora, it is 
probably a form of T. perrottetiana Dene. The petals of this 
species, however, are never more than very slightly retuse and 
can hardly be described as bifid as Llanos indicated for the form | a 
he described. Llanos’s species is not represented among his 
specimens in the de Candolle herbarium.
