496 BURMA, ITS PEOPLE AXD PRODUCTIOXS. 



joints are glabrous and net-vtined, not hooked-pilose like those of Hasskarl's D. 

 Apiirinis, which Miijuel combines with I), stipidaceum, while Baker would make it 

 spionymous with I), spirah. 



*"* Pods and ovary rariously clothed icith glandular or glatidless, straight or hooked hairs. 

 X Pod-joints 4-5 times longer than broad, or if shorter stalk-like narrowed at the base. 

 + Tod-Joints pedicel-like narrowed or abruptly constricted at the base, securiform 

 or crescent-shaped, puberulous. 



° Fod-joints crescent-shaped, abruptly constricted at both ends. 



D. coNciNNTTM, DC. Martaban from 4000 to GOOO feet. 



B. pendulum, Wall. 



Leaves oblong, acute or blunt, strongly parallel-nerved. Pod-joints broadly 

 lunate, tumid, and only 2 lines long, coriaceous, the basal one refracted on a stalk 

 2 lines long thickened club-like at the apex. 



D. (XJeaeia) oBCOKDATUir, Jliq. Maulmain. Sumatra. 



Leaves divaricately obcordate. Pod-joints membranous, broadly lunate, acute 

 and divaricate at both ends, very flat. Spreading or trailing herb. 



° ° Pod-Joints securiform, the basal one long-stalked. 



D. scALPE, DC. Hill forests of Martaban at 4000 to 5000 feet. 



D. sfranguldtum, "\V. A. 



Calyx about a line, the corolla 5 lines long; stalk of basal pod-joint about 1-J 

 line long. 



Baker identifies the D. trichaiilon of Hasskarl's PL Jav. rar. 367 with the above, 

 but this he could only do by simply guessing, for the description does not in the least 

 agree, and the dehiscent pods at once indicate its true affinity (Kurz). 



D. PODOCAEPUM, DC. Ava Hills. 



Calyx and corolla half the size. Stalk of basal pod-joint slender, 1 inch long. 

 If D. laxum, DC, is correctly referred to the above species (as to which I 

 entertain grave doubts), this name has precedence (Kurz). 



-\--\- Pod-Joints truncate at both ends, oblong to linear-oblong and sessile. 

 ° Leaver p innately Z-foliolate. 



D. EECTEVATUM, Grab. Chittagong, Arakan, Pegu, and Kondul. 



Hcdysarum d (fusion, Koxb. non Willd. 

 D. laxiflorum, DC. 



Pod-joints only I3-2 lines long by A-f line broad, densely hooked puberulous, 

 not narrowed at the ends. 



°° Zeaies simjile, the petiole short. 



D. TEEEs, Wall. Ava. Taong-doung. 



The petiole very short. Pod-joints 10-12, about 3 lines long and hardly a line 

 broad, shortly glandular-pubescent. 



X X Pod-Joints narrow, as long or only twice as long as broad. 

 -\- Shrubs or more usually erect or spreading perennials. Pod-Joints usually as 

 long as broad, more or less rotundate with truncate ends. 



° Leaves simple. Pod-Joints indented at the lower suture, about a line long. 

 D. Gangeticum, L. From Pegu, Tenasserim, and the Nicobars. 



ILedysarum collinum, Eosb. 

 D. latifolium, Wight. 



Perennial, erect, slightly apprcssed-pubescent. Racemes elongate and very 

 slender. Pod-joints sparingly and shortly hispid. Leaves acute.
