158 XLVII. § PAPILIONACEE (BAKER). [ Arachis. 
indehiscent, subtorulose, but not articulated, continuous within. Seeds 
1-8, irregularly ovoid.—Low, often prostrate herbs. 
A small genus, the other species confined to Brazil. 
1. A. hypogzea, Linn.; DC. Prod. ii. 474. Stems 1-2 ft. long, 
herbaceous, diffuse, the branches clothed especially above with spreading 
hairs. Stipules an inch deep, the lower half adnate, the points lanceo- 
late. Petioles 1-1} in. long, silky. Leaflets in two pairs without a 
terminal one, obovate, 1-14in. long by more than half as_ broad. 
Flowers axillary, solitary, on long slender pedicels, only the lower ones 
fertile. Pod an inch long by half as thick. 
Cultivated throughout our bounds as an article of food, as it is everywhere in the 
Tropics. It is probably a native of Brazil, to which the six other species of the genus 
belong exclusively. (See De Candolle’s “Geographie Botanique,” Vol. ii. 964). It is 
eaten roasted, boiled or converted into an oil. 
42. ZORNIA, Gmel.; Benth. et Hook. f. Gen. Plant. i. 518. 
Calyx membranous, the two upper teeth subconnate, the lowest lan- 
ceolate oblong, the two lateral ones much shorter. Standard sub- 
orbicular, unguiculate; wings obliquely obovate or oblong ; keel 
incurved, subrostrate. Stamens all connate in a closed tube; anthers 
alternately longer and shorter, attached near the base and versatile. 
Ovary sessile, multiovulate; style filiform; stigma small, terminal. 
Pod compressed, the upper suture nearly straight, the lower deeply 
sinuated, the articulations indehiscent, smooth or echinate.—Herbs, 
with equally pinnate, often punctate leaves. 
A small genus, one polymorphous species everywhere in the Tropics, the rest mainly 
American, one also Cape and Angolan.

1. Z. diphylla, Pers. Syn. ii. 8318. Stems a foot or more long; 
slender, herbaceous, glabrous, diffusely branched from the base. St- 
pules lanceolate. Petioles }—$ in. long, the leaflets in a single pair at 
the apex, lanceolate, 1-1} in. long, 1—$ in. broad, the edge lightly 
ciliated, the surface glabrous. Flowers in lax axillary stalked racemes 
2-3 in. long, 6-8 hidden each by a pair of persistent bracts, which 
are ovate, rigid, }-Zin. long, slightly bristle-ciliated. Calyx 
1}—2 lines long, scarious. Corolla {-8 in. long, purplish. Pod some-
