188 SPECIES BLANCOANAE 
later, Philip. Journ. Sci. 5 (1910) Bot. 116, reduced Mucuna 
imbricata DC. to the older M. nigricans (Lour.) Steud. The 
species, whatever its correct name, extends from northern Luzon 
to southern Mindanao at low and medium altitudes.

Negretia mitis Blanco Fl. Filip. (1837) 588; ed. 2 (1845) 410; ed. 3, 2

DC. (M. lyonii Merr.). 
Blanco’s species was reduced by Fernandez-Villar to Mucuna 
nivea DC., but in 1906 I redescribed it as Mucuna lyonii, which 
Piper and Tracy have apparently correctly reduced to Mucuna 
nivea W. & A.; see U. S. Dept. Agr. Bur. Plant Industry Bull. 
179 (1910) 15, t, 4, f. A; Merr. in Philip. Journ. Sci. 5 (1910) 
Bot. 117. I prefer, however, to consider de Candolle as the 
author of the transfer to Mucuna. The species has been found 
in the Philippines only in cultivation. 
Illustrative specimen from Manila, Luzon, March, 1915, from 
cultivated plants (Merrill: Species Blancoanae No. 863). 
Negretia pruriens Blanco Fl. Filip. ed. 2 (1845) 411 (sp. vel. comb. nov.) ; 
3, 2 (1879) 389, t. 331=MUCUNA PRURIENS (Linn.) DC. 
This species was reduced by Fernandez-Villar to Mucuna 
atropurpurea DC., certainly by error, as de Candolle’s species 
does not extend to the Philippines. I interpret Blanco’s state- 
ment regarding the pods, “Legum. * * * con gsurcos trans- 
versales,” as applying to the distinct transverse depressions 
between the seeds which are evident in fully matured pods; his 
description in all other respects applies exactly, while the species 
is common in the immediate vicinity of Manila and is widely 
distributed in the Philippines at low and medium altitudes. It 
is commonly known as nipai or lipai. The flowers are very 
dark purple in color. The name Negretia pruriens Blanco does” 
not appear in Index Kewensis.

Fernandez-Villar reduced this to Vigna repens Baker, a species 
that does not extend to the Philippines, and moreover one to 
which Blanco’s description does not apply. The description con- | 
forms exactly with Galactia tenuiflora W. & A., this being now
