2-4-foliolate ; leaflets exstipellate, usually sprinkled with pellucid 

 dots ; stipules subfoliaceous ; flowers solitary or ofteuer in interrupted 

 spikes ; peduncles terminal and axillary ; bracts minute or incon- 

 spicuous ; stipules 2, lateral large foliaceous striated, including sub- 

 sessile flower ; bractlets {Northern and tropical America, southern 

 Africa 1 ). 



152. Chapmannia Torr. & Gr. 2 — Calyx membranous, broadly 

 tubular ; tube tapering at base ; apex shortly 5-lobed ; lobes unequal 

 imbricated ; lowest narrower ; superior more or less connate. Petals 

 thin ; standard suborbicular ; wings obliquely obovate ; keel 

 nearly equal to standard, curved obtuse. Stamens 10, 1-adelphous ; 

 filaments connate into a closed tube ; anthers nearly uniform ; 5 

 inserted higher, versatile ; 5 alternate subbasifixed suberect. Grermen 

 sessile ; ovules oo ; style slender elongated ; apex minute stigmati- 

 ferous. Legume subterete rigid ; superior suture nearly straight ; 

 inferior sinuate ; segments long ovoid, longitudinally striated, 

 glandular- muricated, truncate at both ends, 1 -seeded. Seeds oblong 

 exarillate; embryo subovoid; radicle superior conical straight. — 

 An erect herb, branched at base ; leaves impari pinnate ; leaflets few 

 entire exstipellate ; stipules subulate ; flowers 3 in short, simple or 

 somewhat branched, long-pedunculate racemes ; bracts and bractlets 

 (stipules?) small {Florida). 



153. Arachis L. 4 — Receptacle more or less concave, lined by a 

 disk. Calyx gamosepalous ; either tubular or sacciform at base ; or 

 else 2-partite, anterior sepal free to base, 4 superior connate to a 

 considerable height and membranous ; teeth imbricated. Petals 

 very unequal; standard suborbicular, scarcely tapering at base,
