314 NATURAL HISTORY OF PLANTS. 
162° Hallia Tavuns.'—Calyx subcampanulate ; lobes 5, long acute, 
nearly equal. Petals shortly unguiculate; standard orbicular or 
obovate; wings obliquely oblong; keel equal to or shorter than 
wings, curved obtuse. Stamens 10, l-adelphous or 2-adelphous 
(9-1); anthers uniform. Germen sessile; ovule 1, descending; 
style slender inflexed, often dilated at point of inflexion, subulate at 
apex; summit capitate stigmatiferous. Legume small ovoid, 
included in persistent slightly accrescent calyx, membranous thin 
reticulated. Seed filling pericarp ; hilum lateral exarillate-—Under- 
shrubs or low herbs, usually slender, diffuse or prostrate, leaves 1- 
foliolate; stipules 2, adnate to petiole, striated; flowers axillary, 
solitary or more rarely in twos or threes; pedicels slender, articu- 
lated above middle, and bearing at articulation 1-3 more or less 
connate involucriform bracts (Southern Africa’). 
163. Eleiotis DC.’—Calyx gamosepalous membranous ; teeth 5, 
very short unequal. Petals shortly unguiculate; standard sub- 
orbicular emarginate ; wings oblong, adhering to keel; keel obtuse, 
shorter than wings. Stamens 10, 2-adelphous (9-1); anthers 
uniform. Germen sessile ; ovule 1, descending ; style inflexed above 
middle and slightly thickened at point of inflexion ; summit capitate 
stigmatiferous. Legume compressed, unevenly ovate, acute mem- 
branous reticulated indehiscent. Seed reniform exarillate-—A tender 
diffuse herb ; leaves 1- or more rarely 3-foliolate; stipules small 
striated; flowers very small in slender terminal and axillary racemes; 
pedicels usually 2 in axil of each of rather large striated caducous 
bracts* (ast Indies’). 
164, Leptodesmia Brnru.'—“ Calyx deeply cleft ; lobes narrow, 
nearly equal. Standard suborbicular unguiculate; wings obliquely 
oblong, free; keel narrower obtuse. Vexillary stamen free or 
scarcely cohering with remainder close to base; remainder connate ;
