Following F.-Villar, the synonyms Crotalaria pallida Blanco, non Dryand., 
and C. pumila Blanco, non Schrank, are placed here. It is, however, impossible 
to determine from Blanco’s short description whether or not he had this plant, 
but from a knowledge of the region from which he secured his material 
(Mandaloyan, near Manila), and from his description, it seems more probable 
that he had a depauperate specimen of C. linifolia Linn.

The Philippine material here referred to Crotalaria linifolia is rather uniform 
in its narrow leaves, in this character matching specimens in our herbarium 
from Formosa and from the Caroline Islands (Kawakami & Kobayashi 1519; 
Volkens 824, 467); this narrow-leaved form was described by Vogel from Phil- -
