LouKEA Vespertilionis Desv. Journ. Bot. I. 122, t. 5 f. 18. An 

 erect slender herb, sparingly subfastigiately branched ; branches to- 

 wards their tips finely downy with hooked hairs. Leuf-rachis "5-1 in., 

 leaflets usually 1 terminal, rarely 3 ; rigidly subcoriaceous, green usually 

 clouded with white, the terminal one 2-3 in. broad, 'S-'S in. long with 

 two linear or lanceolate spreading or slightly ascending 2-3-nerved 

 halves, apex of each lobe broadly emarginate bristle- tipped ; lateral 

 leaflets, when present, much smaller, obliquely obversely deltoid. 

 Racemes simple or slightly panicled ; 3-6 in. long; pedicels pubescent? 

 shorter than calyx, the lower geminate. Calyx inembranous campanu- 

 late ; in fruit •25-*35 in. long, sparsely pubescent with spreading hairs ; 

 teeth as long as tube, wide-triangular with a strong central nerve and 

 widely reticulate-veined, as is the tube, with slightly weaker secondary 

 nerves. Corolla not longer than calyx. Fod included, 4-5-jointed.

Malayan Peninsula; exact locality not given. Sir W. Norris ! 

 DiSTRiB. Now cosmopolitan in the tropics, but often only planted.

Di:ffuse annuals or biennials. Leaves simple, rarely 3-foliolate, 

 stipellate, subcoriaceous. Flowers in copious axillary racemes. Calyx 

 glumaceous ; teeth deep, often imbricated, the two upper often connate. 

 Corolla not exserted ; standard broad ; keel obtuse, adhering to the 

 wings. Stamens diadelphous ; anthers uniform. Ovary nearly or quite 

 sessile, many-ovuled ; style incurved, stigma capitate. Pod terete or 

 turgid, composed of several indehiscent 1-seeded joints. Species about 

 15 ; weeds, everywhere in the tropics of the old world. 



Alysicarpus vaginalis DC. ; Miq. Flor. Ind. Bat. I, 231. A robust 

 ascending herb, stems 1-3 feet long (var. typica) ; or a dwarf diffuse 

 herb with very slendei' stems and branches spreading 8-12 in. (var. 

 nummularifolia) ; the branchlets slightly downy. Leaves always 1- 

 foliolate, petioles '3 in. long, slender, glabrous, stipules subscarious paral- 

 lel-veined ovate-acute half as long as petioles; leaflets glabrous cordate 

 at base, lowest lanceolate 1*5-2 in. long, '5 in. broad acute, with upper 

 oblong obtuse 1-1-5 in. long and 1 in. wide (in one series of forms) ; or 

 lowest oblong '75 in. long subacute, the upper "5 in. long ovate-obtuse 

 all "3 in. wide (in a second series of forms). Racemes 8-12-fld. lax-fld. 

 1-3 in. long (var. typica) or congested under 1 in. long (var. nummu- 

 larifolia) ; pedicels shorter than calyx. Calyx "12 in. glabrescent, 

 teeth linear-setaceous longer than tube. Corolla pale-yellow tinged with
