ASCLEPIADACEAE 317 
This was described from cultivated specimens, Blanco de- 
finitely stating that its seeds were sent to him from China. 
Fernandez-Villar was wholly wrong in referring it to the en- 
demic Toxocarpus gracilis Dene., to which Blanco’s description 
does not apply. It definitely is an asclepiadaceous, not an apocy- 
naceous plant, and is undoubtedly the same as Stephanotis chi- 
nensis Champ.; Blanco’s specific name is the older. 
CENTROSTEMMA Decaisne 
Asclepias carnosa Blanco Fl. Filip. (1837) 208; ed. 2 (1845) 147; ed. 3, 
1 (1877) 263, t. 402 bis, non Linn. f.=CENTROSTEMMA MULTI- 
FLORUM (Blume) Dene. (Hoya multiflora Blume). 
This species is of wide distribution in the forests of the Phil- 
ippines, growing at low and medium altitudes. It usually occurs 
as an epiphyte on decaying parts of living trees. Centrostemma 
lindleyanum Dene., described from Philippine material, is a 
synonym,

DISCHIDIOPSIS Schlechter 
Marsdenia parasitica Blanco Fl. Filip. (1837) 120 (sp. nov.) (parasita) ; 
ed. 2 (1845) 86; ed. 3, 1 (1877) 156=DISCHIDIOPSIS PARASITICA 
(Blanco) comb. nov. [Conchophyllum merrillii Schltr. ex Merr. Fl. 
Manila (1912) 380]. 
Marsdenia parasitica Blanco was reduced by Fernandez-Villar 
to Hoya parasitica Wall., a species that does not extend to the 
Philippines, and one to which Blanco’s description does not at 
all apply. In my previous consideration of Blanco’s species 
I considered it as certainly a species of Hoya. However, a 
careful examination of Blanco’s description conclusively shows 
that he was describing no Hoya: “corola de figura de vinagera 
* * * eon la garganta cerrada con una corona membranacea 
* * * Jag flores encarnadas,” etc. Among all the Philip- 
pine Asclepiadaceae known to me, his description applies only 
to Conchophyllum merrillii Schitr., a species that occurs on 
mango trees in the vicinity of Manila, and which flowers from 
March to July. I have absolutely no hesitation in making this 
transfer of Blanco’s species to Dischidiopsis, and identifying 
with it Conchophyllum merrillii Schltr.
