308 NATURAL HISTORY OF PLANTS. 
2-4-foliolate ; leaflets exstipellate, usually sprinkled with pellucid 
dots ; stipules subfoliaceous ; flowers solitary or oftener in interrupted 
spikes ; peduncles terminal and axillary; bracts minute or incon- 
spicuous; stipules 2, lateral large foliaceous striated, including sub- 
sessile flower; bractlets 0 (Northern and tropical America, southern 
Africa’). 
152. Chapmannia Torr. & Gr.’—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. Germen 
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, l-seeded. Seeds oblong 
exarillate; embryo subovoid; radicle superior conical straight.— 
An erect herb, branched at base; leaves imparipinnate ; leaflets few 
‘entire exstipellate ; stipules subulate; flowers’ in short, simple or 
somewhat branched, long-pedunculate racemes ; bracts and bractlets 
Stipules?) small (Florida). 
153. Arachis L.\—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,
