India and Ceylon to southern China and Formosa, and northern Australia, but 

 not as yet reported from the Malay Peninsula or Archipelago. 



The earliest specific name for this species is possibly supplied by Flemingia 

 polysperma Moon Cat. (1824) 54, but the identity of Moon's species appears to 

 be doubtful, as it is questionably referred here both by Wight & Arnott, and by 

 Trimen. The original use of Crotalaria f nervosa Grab, is a nomen nudum, anil 

 has no standing, but Pycnospora nervosa was published by Wight & Arnott, and 

 it is considered that this name has precedence over the more commonly used 

 P. hedysaroides R. Br., which was mentioned by Wight & Arnott only incidentally. 



51. ALYSICARPUS Neck. 



Calyx equaling several joints of the pod; pods glabrous, not at all rugose; leaves 

 linear or lanceolate-linear; racemes slender, 8 to 15 cm long. 



1. A. bupleurifolius 

 Calyx equaling the first or second joint of the pod only; pods glabrous or 

 puberulent, distinctly rugose; leaves various, but never linear or linear- 

 lanceolate; racemes less than 8 cm long. 

 Erect or suberect, often 1 m high, the branches sometimes hirsute with long, 

 scattered, spreading hairs, never puberulent; leaves elliptic to elliptic- 

 oblong, usually retuse at both ends; racemes lax, pods entirely glabrous. 



2. A. vaginalis 



Prostrate or spreading, rarely ascending, the branches usually less than 50 cm 



long; branchlets minutely puberulent; leaves exceedingly variable, acute, 



acuminate, or at least apiculate at the apex, never retuse; racemes dense; 



pods puberulent 3. A. nummularifolius

India and Ceylon, the Mascarene Islands, to southern China, Java, Timor, and 

 Polynesia; not reported from the Malay Peninsula. 



Tetragonololus simplidfolius Blanco is referred here with doubt, as the short 

 description does not apply in all respects; it is perhaps the same as A. tetragono- 

 lobus Edgw., where it was referred by F.-Villar, but I have seen no Philippine 

 material at all approaching the latter species, which is definitely known only 

 from India.
