192 SPECIES BLANCOANAE 
name the species that Roxburgh described as P. aureus. The spe- 
cies is commonly known as balatong and mongos and is widely 
cultivated in the Philippines; see Merrill Interpret. Herb. Amb. 
(1917) 283.

Fernandez-Villar considered that Blanco correctly interpreted 
the Linnean species, but the plant Blanco described is manifestly 
the form described by Linnaeus as Dolichos sinensis. It is uni- 
versally known in the Philippines as sitao, a name of Chinese 
origin, and is very commonly cultivated in the vicinity of Manila. 
It is always planted and is not established in the Archipelago.

This reduction follows Fernandez-Villar, although the speci- 
mens I have received under the Tagalog name quibal do not 
agree entirely with Blanco’s description. It is certain, how- 
ever, that the plant he described is a form of the cowpea. It is 
the plant that has been referred to Vigna unguiculata Walp., 
but Piper has recently shown that the Linnean Dolichos ungui- 
culatus is a Phaseolus, not a Vigna; Torreya 12 (1912) 189-190. 
Vigna catjang Walp.—V. cylindrica (Linn.) Merr. is frequently - 
considered as a synonym of V. sinensis (Linn.) Endl., but by © 
some authors is treated as a variety of that species. I do not — 
agree with Fernandez-Villar in referring Dolichos sesquipedalis — 
Blanco Fl. Filip. ed. 2 (1845) 402; ed. 3, 2 (1879) 375, to this 
form, as Blanco definitely describes the Linnean species with 
the very long pods “mas de un pie hasta pie y medio de largo,” 
the form commonly cultivated in Manila and known as sitao, 
described by Blanco under the name of Phaseolus caracalla; see 
above, Species Blancoanae No. 397. .
