is widely distributed in the Philippines at low and medium alti- 
tudes as a weed in open wet places, old rice paddies, etc.; it is 
undoubtedly an introduced plant in the Archipelago.

CROTALARIA LINIFOLIA Linn. f. (C. stenophylla Vog.). 
Bianco was apparently saith: in his interpretation of the 
species described by the younger Linnaeus, although the Philip- 
pine plant differs notably from the Indian form in its narrow 
leaves. Blanco erred in describing the plant as a new genus 
and species in the second edition of his Flora de Filipinas. If 
the Philippine form be distinct, the oldest valid name is Crota- 
laria stenophylla Vog. (1843), and a synonym is Crotalaria for- 
mosana Mats. (1900), figured in Journ. Coll. Sci. Univ. Tokyo 
22 (1906) 103, t. 10. It is widely distributed in Luzon at low 
and medium altitudes and occurs also in Mindanao, Formosa, 
and the Caroline Islands. Crotalaria pallida Blanco was reduced 
by Fernandez-Villar to C. sessiliflora Linn., but after a critical 
study of Blanco’s short and very imperfect description, the 
geographic distribution of the various simple-leaved species of 
Crotalaria in Luzon, and their seasons of flowering, I am con- 
vinced that the form Blanco described under this name is merely 
a dwarfed form of Crotalaria linifolia Linn. (C.  steno- 
phylla Vog.). He

This species was reduced by Fernandez-Villar to the Indian | 
Alysicarpus tetragonolobus Edgw., a species that does not occur 
in the Philippines and one to which Blanco’s description does — “a 
not at all apply. The species is unquestionably identical with 
Indigofera unifoliolata Merr., as Blanco’s description applies 
perfectly, while the distribution of the plant in Luzon is in con- 
formity with the habitat of Tetragonolobus simplicifolius Blanco,
