SuBGEN. 1. ZooPHTHALMUM. Perennial climbers ; seeds large more 

 or less flattened, witli a long Lilum extending round the greater part of 

 the periphery. 



§ CiTTA. Pods plaited, across their faces. 



1. MucUNA iMBRiCATA UC. Prodx. II, 406. A large woody climber 

 with slender glal)resceDt branches. Leaves 9-15 in. long ; leaflets 8, 

 membranous, green, glabrous above, glabrous or with a few adpressed 

 hairs beneath, ovate-oblong cuspidate, base rounded — of lateral leaflets 

 obliquely, 5-7 in. long, 3-3'5 in. across, petiole glabrous 4-8 in. long, 

 petiolules "2 in., stipels subulate '15 in, ; stipules linear "25 in. long. 

 Inflorescence of lax 8-10-fld. axillary racemes, pedicels "35 in. long 1-3 

 together from swollen nodes towards upper third to fourth of peduncle 

 5-15 in. long, and in the axils of large boat-shaped deciduous bracts 

 1'25 in. long 1 in. wide glabrous on both surfaces rounded at apex 

 except the acute or subacute lowest, forming at first a strobilate head. 

 Calyx "75 in. long sparsely covered externally with brown deciduous 

 irritating bristles, tube wide-campanulate hardly longer than the wide 

 trianofular teeth ; flower-buds with a bracteole similar to bracts but 

 much smaller and more early deciduous, at base of calyx. Corolla 

 2-2*25 in. long dull purple or white with purple spots ; keel abruptly 

 inflexed at tip standard 1 in. across 1-25 in. long ; wings '5 in. wide. 

 Fod oblong 4"5-6 in. long 2*25 in. acro&s, wings along the sutures '5 in. 

 wide, plaits '35 in. deep hardly crossing the wings ; clothed in all parts 

 with brown deciduous bristles; seeds 2-3. Bak. in Flor. Brit. Ind.

Most nearly related, amongst Malayan species, to Stizolohium Junghuhnianum 

 Kuntze {Rev. Gen. Plant. I, 208) from Java^, which has very similar bracts. The pods, 

 however, are in that species slightly narrower with rather narrower wings across 

 which the plaits extend more completely. The branches, petioles, leaves and bracts 

 of M. Junghuhniana are moreover strigosely hispid and the calyx and pods are 

 more densely bristly. Nearly related also is 3f. cyanosperma K. Schum., from the 

 Moluccas.
