338 ENUMERATION OF LEGUMINOSA., 
Enumeration of LEgGuMINOSE, indigenous to SOUTHERN 
Asia, and CENTRAL and SOUTHERN ÀFRICA, by GEORGE

XVIII. Lista. E. Mey. 
The habit and most of the characters of the single species 
known of this genus are so exactly those of the section Poly- 
olbium of Lotononis, thatit ought probably to be added to 
the latter genus as a mere section, yet the singular manner 
in which the pod is folded is considered among Hedysareæ, 
for instance, as affording a sufficient character, and I have 
not observed any approach to it in any Lotononis I am ac- 
quainted with. 
1. L. heterophylla (E. Mey.! Comm. p. 81.)— Habitus Lo- 
tononidis trichopode. Flores subcapitato-racemosi, pedunculo 
communi foliis longiore. Calyx et corolla sectionis Poly- 
lobii. 
South Africa, to the north-east of the Cape Colony, on dry 
stony hills near Gaatje, and in the plain near Wildshuts- 
hoek, Drège! In the Stormbergspruit and on the Mooze 
River, Burke! also n. 2297 of Burchell’s Catalogue.

This genus is again composed of a single species, the cha- 
racters and synonyms of which are fully enumerated by 
Wight and Arnott (Prodr. 1, p. 195), to which may be added 
that the pod usually opens out on the carinal suture only, as- 
suming much the appearance of the fruit of a Cleome. The 
habit of the plant is that of the more slender Argyrolobia, OF — 3 
of some Lotononides of the section Leptis. It is readily dis- 
tinguished from both genera by the keel petals scarcely CO" 
hering to each other, or often entirely free. The flowers are- 
very small. a
