pines in the settled areas at low altitudes. It is extensively 
planted in hedge rows, etc., and is also thoroughly naturalized. 
Introduced from Mexico at an early date. Millettia luzonensis 
A. Gray is a synonym. 
Illustrative specimen from Antipolo, Rizal Province, Luzon, 
January, 1914, there known as madre cacao and cacauate, the 
former of Spanish, the latter of Mexican origin (Merrill: Species 
Blancoanae No. 613). 
SESBANIA Scopoli 
Coronilla emerus Blanco FI. Filip. (1837) 582, non Linn.=Sesbania canna- 
bina (?) Blanco op. cit. ed. 2 (1845) 418; ed. 8, 2 (1879) 400, non 
Poir.—SESBANIA ROXBURGHII Merr. in Philip. Journ. Sci. 4 (1909) 
Bot. 269, 5 (1910) Bot. 74. 
This was correctly reduced by Fernandez-Villar to Sesbania 
aculeata Poir. var. paludosa (Roxb.) Baker=Sesbania paludosa 
Prain, non Jacq. (Aeschynomene paludosa Roxb.), but Rox- 
burgh’s specific name is invalid under Sesbania. The species 
is known in the Philippines only from the region of Lake Bay, 
Luzon, where it grows in shallow water. 
Illustrative specimen from Siniloan, Laguna Province, Luzon, 
January, 1915, there known as balacbac, a name in common 
use for the suffrutescent species of Sesbania (Merrill: Species 
Blancoanae No. 880). 
SESBANIA GRANDIFLORA Pers.; Blanco Fl. Filip. (1837) 599; ed. 2 
(1845) 418; ed. 8, 2 (1879) 399, ¢. 291. 
Persoon’s species was correctly interpreted by Blanco. It is 
common and widely distributed in the Philippines at low alti- 
tudes, usually planted, sometimes spontaneous. It is certainly 
of prehistoric introduction in the Philippines. 
Illustrative specimen from Manila, Luzon, January, 1914 
(Merrill: Species Blancoanae No. 599). 
AESCHYNOMENE Linnaeus 
Aeschynomene roxburghii Spreng.; Llanos Frag. Pl. Philip. (1851) 83; 
F.-Vill. & Naves in Blanco FI. Filip. ed. 3, 4* (1880) 64=AESCHY- 
NOMENE INDICA Linn. 
Sprengel’s species was correctly interpreted by Llanos, but 
the Linnean name is the proper one for it. It is widely dis- 
tributed in the settled areas of the Philippines, growing at low 
and medium altitudes in open wet places. 
Illustrative specimen from Arayat, Pampanga Province, Lu- 
zon, February, 1915 (Merrill: Species Blancoanae No. 762).
