 form, hilum oblong. — Twining herbs ; leaves pinnate, 3 or rarely 

 1-5-foliolate, stipellate ; stipules minute or striated ; flowers 5 in a 

 short raceme or solitary or fascicled at axils ; bracts and bractlets 

 usually linear or setaceous persistent {Tropical and Andine America,

35. Periandra Mart/ — Flowers of Kennedya or Clitoria ; recep- 

 tacle and calyx subcampanulate shorter than in these ; lobes of calyx 

 unequal ; lowest usually longer ; 2 highest more or less connate. 

 Petals dissimilar ; standard broadly obovate or suborbicular, with 

 short curved plaited claw ; wings oblique ; keel broad, slightly 

 shorter than wings. Stamens 10 (of Clitoria); vexillary stamen 

 sometimes more or less connate with the others. Germen subsessile 

 a>-ovulate ; style subclavate at apex, beardless. Legume linear 

 piano-compressed, with both sutures thickened, 2-valved. Seeds 

 exarillate compressed. — Herbs or shrubs, erect or twining ; leaves 

 3-foholate (lower leaves more rarely 1-foliolate), stipellate; stipules 

 striated; peduncles axillary i-3-flowered or at extremities of branches

4 Flowers apetalous in Martia mexicana 

 Ztrcc. fin Abh. Munch. Altai., i. 339, t. 14, 15), 

 which, according to Bemtham (loc. cif.), is a 

 species of Cologania. This genus is scarcely to 

 be distinguished from Amphicarpa by its exauri- 

 culate standard. The calyx is identical in some 

 spt cies.
