A glabrous perennial, climbing on bushes along the coasts. Leaflets as in G. 

 ensiformis. Flowers as in C. ensiformis but fewer. Pod 5 in. long, 2-2| in. wide, very 

 turgid. 



There is no doubt that this plant is specifically distinct from G. ensiformis, with 

 which it has been placed in the F. B. I. ; the separable endocarp at once amply 

 differentiates it. This, however, is the plant to which the name G. obtusifolia pro- 

 perly belongs. For G. obtusifolia DC. is Dolichos obtusifolius Lamk. and Dolichos 

 obtusifolius Lamk. is the plant figured by Rheede (loc. cit.). It is, moreover, Dolichos 

 rotundifolius Vahl., of which indeed De Candolle had seen a specimen, thus confirm- 

 ing the conclusion that Roxburgh had already formed. This, from his drawing, is 

 without any possibility of doubt Roxburgh's Dolichos rotundifolius. 



The plant named G. obtusifolius in the F. B. I. is certainly the plant figured by 

 Dr. Cleghorn (Madr. Journ. n. s. i. t. 4) and is in all probability the Chinese plant 

 that Roxburgh named D. obcordatus. The pods of the two are quite alike and differ 

 totally from those of G. turgida. The writer cannot, however, separate this Madras 

 and Chinese species from Dolichos lineatus Thunbg. (Canavalia lineata DC), either 

 by Thunberg's or De Candolle's descriptions, by the specimens in Herb. Calcutta 

 received from Japan, or by the figure published in the Somoko Dusets, ed. ii. xiii. t. 20. 

 In this indeed he only agrees with Mr. Baker. The true name of the 0. obtusifolia of 

 the F. B. I. is therefore C. lineata DC. In any case the species now being discussed 

 should be put in some particular place ; as arranged in the F. B. I. it is given, if it 

 comes from India, under G. obtusifolia and, if it comes from Malaya, is made a 

 variety of G. ensiformis ; it cannot well be both. 



71. DIOCLEA PL. B. K. 



1. Dioclea replexa Hook. fil. Leaves beneath sparsely hairy or 

 glabrescent. 



Add to synonyms of F. B. I.: — Dolichos hexandra Roxb. Hort. 

 Beng. 55; and delete the synonyms D. javanica and B. Fergusonii. 

 Add to localities : — Andamans ; very common. 



Roxburgh's Dolichos hexandra came from Silhet where Hooker and Thomson 

 also afterwards found the species ; in Herb. Calcutta Roxburgh has left a 

 beautiful coloured figure of the plant. It is particularly plentiful in the Anda- 

 mans. The vexillary stamen in both the Indian Diocleas is free at the base though 

 not above ; is rather shorter than the others and has a perfect anther ; the anthers 

 of the 9 stamens united in the keel-sheath are alternately perfect and abortive ; 

 there are thus 5 perfect anthers in the sheath and a sixth perfect on the vexillary 

 stamen ; hence Roxburgh's very excellent specific name.
