Widely distributed in the Philippines at low altitudes; India and Ceylon to 

 southern China and Formosa, the Malay Peninsula and Archipelago to Polynesia; 

 introduced in tropical America. 



This was reduced by Miquel as a variety of Alysicarpus vaginalis, in which 

 he has been followed by later authors. Prain states that the distinguishing 

 characters are the spreading habit and condensed racemes of nummularifolius, and 

 the ascending stems and lax racemes of vaginalis, and that the leaf characters 

 depended upon by many botanists are not sufficiently constant; so far as our 

 material goes, other apparently good characters are the much larger size, retuse 

 leaves, and glabrous pods of vaginalis, and the smaller size, acute, acuminate or 

 apiculate leaves, and puberulent pods of nummtilarifolius. 



Specimens identified by Perkins^* as A. vaginalis are rather A. nummularifolius, 

 as well as those so determined by myself.^" The leaves are exceedingly variable, 

 elliptic, ovate, oblong, and even lanceolate ones being sometimes found on the 

 same specimen; while on some plants, only elliptic, or ovate, or oblong leaves are 

 found. 



The original Hedysarum nummiilarifolium Linn, is a mixture, but I consider 

 that it is typified by the reference to Petiver Gaz. 41, t. 26, f. J/, "Onohrychis 



maderaspat. nummulariae folio, " from which the specific name was taken. 



Mr. Oakes Ames has kindly supplied me with a tracing of this figure, and it 

 unquestionably represents the species as here interpreted. Linnaeus' first reference 

 is to ','Fl. zeyl. 288," and the specimen in Hermann's Herliarium is Indigofera 

 echinata Willd.""
