Hippocrepis rhomboidea Blanco Fl. Filip. (1837) 585 (sp. nov.) =Desmo- 
dium spirale DC.; Blanco op. cit. ed. 2 (1845) 408; ed. 3, 2 (1879) 
385—DESMODIUM PROCUMBENS (Mill.) A. S. Hitche. 
This species is locally abundant, but by no means of general 
distribution in the Philippines, occurring at low altitudes and 
only in the settled areas; undoubtedly introduced from tropical 
America. 
Illustrative specimen from Manila, Luzon, December, 1913 
(Merrill: Species Blancoanae No. 360). 
Hippocrepis comosa Blanco Fl. Filip. (1837) 584, non Linn.= Desmodium 
diversifolium Blanco op. cit. ed. 2 (1845) 408; ed. 3, 2 (1879) 384, non 
DC.=DESMODIUM LAXIFLORUM DC. 
This species was reduced by Fernandez-Villar to Desmodium 
gangeticum DC., in which, in part, he was perhaps correct. 
Blanco describes his plant as having sometimes simple leaves, 
but more often 3-foliolate ones. There is nothing in the descrip- 
‘tion that definitely determines just what form he intended, but 
as D. laxiflorum DC. is common and widely distributed in the 
Philippines at low altitudes, and as there is nothing in Blanco’s 
description that does not agree with the species, except the 
statement “‘hojas unas veces simples,” the present identification 
of Blanco’s species is assumed. The form with simple leaves 
included by Blanco was probably Desmodium gangeticum DC. 
Illustrative specimen from Antipolo, Rizal Province, Luzon, 
November, 1914 (Merrill: Species Blancoanae No. 175). 
Hippocrepis humilis Blanco Fl. Filip. (1837) 585 (sp. nov.) =Desmodium 
parvifolium Blanco op. cit. ed. 2 (1845) 408; ed. 3, 2 (1879) 386, non 
DC.=DESMODIUM TRIFLORUM (Linn.) DC. 
This species is very common and widely distributed in the 
settled areas of the Philippines at low and medium altitudes, 
in and about towns, in waste places, etc.

. Keschynomene arborea Linn.; Blanco Fi. Filip. ed. 1 (1837) 581 (Aeschi- 
namene); ed. 2 (1845) 406; ed. 3, 2 (1879) 381=DESMODIUM 
UMBELLATUM DC. , 
The Linnean specific name arborea has priority over the 
specific name wmbellatum, but the former is apparently in- 
validated in Desmodium by Desmodium arboreum Sweet. The 
species is common along the seashore throughout the Philippines.
