slightly prominent. Calyx deeply 5-lobed; lobes subequal rather 
thick valvate persistent. Petals very unequal; standard broadly 
orbicular or reniform, apex often emarginate; wings oblong, often 
falcate ; keel oblong, broader than wings. Stamens 10, free perigy- 
nous; anthers uniform. Germen inserted by short slender stalk in 
bottom of receptacle closely surrounded by a disk at base; style 
incurved ; apex truncate or capitate, stigmatiferous ; ovules 4— 2, 2- 
seriate, long-funiculate campylotropous. Legume inflated sub-gibbous, 
ovoid or shortly cylindrical, obtuse often oblique inflated. Seeds 
few or o, small exarillate long-funiculate.—Shrubs or undershrubs ; 
leaves alternate simple, or more rarely pinnate or digitate; terminal 
leaflet sessile; stipules minute or 0; flowers’ axillary or terminal, 
solitary or in small racemes; bracts and bractlets minute or 0 
(Australia’). 
248. Mirbelia Su.i—Calyx gamosepalous imbricated ; 2 superior 
lobes broader, higher connate. Petals unguiculate; standard reni- 
form or broadly orbicular; wings obliquely oblong; keel equal to 
wings or shorter. Stamens 10, free. Germen sessile or stipitate ; 
ovules 2-0; style usually short incurved; apex capitate stigmati- 
ferous. Legume oblong or ovoid, turgid, within longitudinally 
2-locellate by 2 longitudinal false-septa, springing one from 
pushed-in placenta, one from anterior suture (as in Astragalus) ; 
endocarp often separating from exocarp at maturity ; seeds 1, 2, or 
oo, exarillate.—Shrubs; leaves simple, alternate and opposite or 
verticillate, more rarely 0; stipules small setaceous or 0; flowers‘ 
axillary or terminal, solitary fascicled or racemose; bracts and
