LEGUMINOSAE 179 
which was from near sea level at Paranaque, Rizal Province, 
Luzon. Blanco’s specific name is invalidated in Indigofera by 
I. simplictfolia Lam. 
Illustrative specimen from Pantay, Rizal Province, Luzon, 
September, 1915 (Merrill: Species Blancoanae No. 965). 
Indigofera angustifolia Blanco Fl. Filip. (1837) 596; ed. 2 (1845) 415; ed. 
8, 2 (1879) 394, non Linn.=INDIGOFERA HIRSUTA Linn. | 
Indigofera tinctoria Naves in Blanco Fl. Filip. ed. 3, (1877-838) t. 168, 
non Linn. =INDIGOFERA HIRSUTA Linn. 
This is common and widely distributed in the settled areas of 
the Philippines at low altitudes; it is certainly an introduced 
species in the Archipelago. 
Illustrative specimen from Umingan, Pangasinan Province, 
Luzon, May, 1914 (Merrill: Species Blancoanae No. 403). 
INDIGOFERA TINCTORIA Linn.; Blanco Fl. Filip. (1837) 591; ed. 2 
(1845) 413; ed. 3, 2 (1879) 393. 
Blanco’s conception of the Linnean species was reduced by 
Fernandez-Villar to Indigofera anil Linn., but the description 
is unmistakably J. tinctoria Linn., as the pods are described by 
Blanco as two inches in length: “Legum. * * * de dos pul- 
gadas de largo”, one of the essential characters by which Indigo- 
fera tinctoria L. is distinguished from J. anil Linn. The species 
was formerly extensively cultivated in Luzon, but is now found 
only as an occasional plant in waste places. It is widely distri- 
buted in the settled areas at low and medium altitudes but is 
much less common than Indigofera suffruticosa Mill. (J. andl 
Linn.). 
Illustrative specimen from Manila, Luzon, March, 1915 
(Merrill: Species Blanconaae No. 826). 
Indigofera argentea Blanco Fl. Filip. ed. 2 (1845) 415 (in nota); ed. 3, 2 
(1879) 394 (in nota), non Linn.=INDIGOFERA SUFFRUTICOSA 
Mill. (7. anil Linn.). 
This species is common and widely distributed in the Philip- 
pines, occurring throughout the Archipelago in the settled areas 
at low altitudes. It is an introduced plant in the Philippines. 
Blanco’s description of Indigofera tinctoria Linn. as having 
fruits “de dos pulgadas de largo” indicates clearly that he was 
describing the Linnean species in spite of previous reductions 
of Indigofera tinctoria Blanco to I. anil Linn. (=I. suffruticosa 
Mill.). 
Illustrative specimen from Antipolo, Rizal Province, Luzon, 
October, 1914 (Merrill: Species Blancoanae No. 124).
