WESTERN PENINSULA. 



Branches obscurely grey-downy. Leaflets 3 in all our specimens, but said to be 

 sometimes 5, 2-4 in. long, rounded at both ends, slightly emarginate, clothed with ob- 

 scure adpressed grey hairs below. Racemes shorter and less copious than in P. indi- 

 cus, the pedicels shorter. Calyx |-^ in. ; teeth deltoid, minute. Limb of standard not 

 longer than the calyx. Pod silky at first, the same size as in P. indicus, but the centre 

 more turgid, wing narrower and style brought down to the basal corner.

Plains of the WESTERN PENINSULA and CEYLON. 



Leaflets thicker than in the others, green and glabrous on both surfaces, 3-5 in. long, 

 obtuse or subacute, sometimes slightly or deeply emarginate, often twice as long as 

 broad, the main veins much closer, more numerous, and more prominent than in the 

 others. Racemes ample, copious, lateral and terminal, the branches thinly clothed with 

 brown pubescence ; pedicels - 2 \-^ in. Calyx \-~ in., finely brown-downy ; teeth deltoid, 

 the two upper ones the largest. Corolla twice the length of the calyx ; sheath of 

 stamens sometimes finally split down the keel as well as the top. Pod 1-2 in. broad, 

 the same shape as in the last, but the seed smaller and wing broader.
