Though common in Tenasserim where it has been collected by Wallich (n. 5788 

 M !) and Heifer (n. 1648!) as well as in Mergui where it has been obtained by 

 Griffith (n. 568!) and Proudlock (n. 14 !), this is not present in Calcutta from any 

 locality within the Straits Settlements. It is rather more closely related to Desmo- 

 dium alatum, which has bi'oader pods, than to the preceding species, but it is equally 

 distinct from both. It appears to be an almost exclusively littoral form ; there are 

 however two inland gatherings at Calcutta, both from Silhet and both collected by 

 Mr. Clarke (n. 14352 ! and n. 42702 !). 



It should be noted that Iledysarum alatum Roxb. is not the species described by 

 De Candolle as Desmodium alatum ; Roxburgh's H. alatum is exactly equivalent to 

 Linnaeus' II. triquetrum. Roxburgh's H. triquetrum on the other hand is not 

 Linnaeus' plant but is Desmodium pseudo -triquetrum DC, a species confined to 

 Northern India, the lower Himalayan slopes, and the mountains of Assam. D. ala- 

 tum DC, the plant with broad pods described in the Prodromus, occurs in Khasia, 

 Cachar and Chittagong without appearing in India proper or in Burma and the 

 Malay Peninsula ; it recurs, however, in Java. The present species, D. auriculatwm, 

 has not been found in Java but is met with again in Timor. 



Subgen. 6. Pleurolobium DC. Erect undershrubs, with large 

 leaves. Flowers racemose ; pods indistinctly jointed, dehiscing in a con- 

 tinuous line along the ventral suture. 



16. Desmodium gyroides DC. Prodr. II, 316. A shrub about 10 

 feet high with terete sparsely pubescent branches. Leaves 2'5-3 in. long 

 3- or often only 1-foliolate, petiole '75 in, long, slender glabrescent • 

 leaflets membranous, oblong or ovate-oblong obtuse, pale-green glabrous 

 above, very thinly adpressed-pubescent beneath, J'75-2 in. long, 1-1*25 

 in. wide, lateral nerves 6-8 pairs visible beneath ; lateral leaflets if 

 present similar but much smaller, *5 in. long, *4 in. wide. Inflorescence 

 in dense axillary and terminal at first strobilate racemes, with large 

 imbricating scarious soon deciduous ovate-acute bracts, '25 in. long »2 in. 

 wide, pedicels finely-pubescent at length patent, '25 in. long. Calyx '1 

 in., wide-campanulate, teeth triangular half as long as tube. Corolla "35 

 in. long, 2 in. across, purple. Pod 1-1'5 in. long, "2 in. wide, falcate ; 

 joints 6-10, dehiscing along the lower slightly indented suture but not 

 separating from each other, copiously pubescent with a felted rusty 

 tomentum. Wall. Cat. 5728 ; W. & A. Prodr. 227 ; Miq. Flor. Ind. Bat.
