]62? Hallia Thunb. 1 — 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, 1-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 2 ). 



163. Eleiotis DC. 3 — 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 4 {East Indies"). 



164. Leptodesmia Benth.* — " Calyx deeply cleft ; lobes narrow, 

 nearly equal. Standard suborbicular unguiculate ; wings obliquely 

 oblong, free ; keel narrower obtuse. Yexillary stamen free or 

 scarcely cohering with remainder close to base ; remainder connate ;
