There is very little doubt as to the correctness of this inter- 
pretation of Blanco’s Stapelia quadrangula. The reduction was 
originally made by Fernandez-Villar, and I consider it to be 
correct. The species is of very local occurrence in Luzon. The 
old stems are remarkable for their thick corky wings or ridges.

This species is common in thickets in the neighborhood of 
Manila and is widely distributed in the Philippines at low and 
medium altitudes. It is commonly known as mil leguas, from 
its similarity to Telosma odoratissima (Lour.) Coville, this 
Spanish name properly belonging with the latter species. There 
is absolutely no doubt as to the identity of Blanco’s Pergularia 
procumbens and no doubt as to the correctness of the reference 
here of his Cynanchum ? hirtum (non Linn.) ; of the former 
Blanco describes only flowering specimens, of the latter only 
fruiting specimens. Fernandez-Villar erroneously reduced Blan- 
co’s Cynanchum ? hirtum to Dregea viridifiora Benth. Fresh 
mature fruits of Telosma procumbens (Blanco) Merr. are green, 
lanceolate-pyramidal, about 15 cm long, 3 to 3.5 cm wide, about 
2.5 em thick, nearly square in cross section, or one side some- 
- what narrower than the other, with a thick, coarsely and irregu- 
larly toothed wing 3 to 7 mm wide running nearly the entire 
length of each angle, base rounded or obtuse, apex acuminate, 
smooth. The fruits dry very slowly, and the younger ones are 
cooked and eaten by the Filipinos. This description is quite in 
agreement with Blanco’s description of the fruits of Cynan- 
chum ? hirtum except that normally, at least, they are smooth, 
not “verrugoso,” i. e. warted. F.-Villar reduced ‘Pergularia
