racemose, 7-10 mm. long. Calyx tube about 2 mm. long, 
obliquely attached (sometimes but obscurely so, with teeth 
subulate and about as long as the tube (short in A. Meta- 
nus). Peduncles about as iong as leaves, the floral rachis 
twice as long. Leaflets about 2-3 cm. long, elliptical or 
narrower, mostly obtuse. Stipules adnate, reflexed. Stems 
striate, 1-2 ft, long, rather flexuous. Internodes 3-0 cm. long. 
Plants very pubescent except in A. metanus. Tropical life 
zone. 
AB3CDE. Pubescence spreading. Leaflets moderately petio- 
lulate. 
Pods racemose. Flowers nearly white. Plants shaggy 
with partly spreading silky hairs. 39 Julianus. 
Pods spicate. Flowers dark-purple. Plants hoary 
above with densely woolly. hairs. 40 proriferus. 
AB3CD2E. Pods nearly glabrous, ventral suture humped in 
the middle and about one-half as convex there as the 
dorsal. Upper leaves sessile or nearly so. Leaflets about 
9 pairs, 2-3 cm. long, distant, acutish, long-petiolulate, nar- 
rowly to ıinear-elliptic, flat. Pubescence ‘closely ap- 
pressed. Tall plants and probably shrubby. 
Pods much flattened except at very base, ro mm. long. 41 metanus. 
Pods not flattened except at very tip. 2 cm. long. 42 Vaseyi. 
AB3C2D. Pods 410 mm. Jona, reflexed in short and close ra- 
cemes, very greatly inflated, globose-ovate, not at all oblique 
not compressed, not sulcate noticeably, not at all narrowed 
at base, the minute and flat tip scarcely visible. Stems as- 
cending, annuals or winter annuals. 
Pods jointed to a minute stipe, 6-8 mm. long. 43 Thurberi 
AB3C3D. Pods about 5 mm. high and 12 mm. long, half-oval, 
inflated very little and only in the middle, much laterally 
flattened till nearly flat, erect and appressed. Apparently 
perennials of the Lower Temperate life zone. 
Pods nearly flat. ; 44 Palmeri. 
AB4C. Slender or tall plants with minutely woolly pubescence, 
stubby cream-colored flowers in dense spikes which do not 
elongate with age and on conspicuous peduncles which elon- 
gate with age. Leaves sessile, with many pairs of nearly 
contiguous leaflets, which are cuneate below. Pods taper 
pointed. Tropical plants. = 
Pods rigid, small, little inflated, nearly smooth. Tall perennials. 
i 45 Ae rta 
Pods papery, rather large, much inflated, hairy. Annu 46 Hornii. 
A2B. Pods small, rarely 2 cm. long sometimes 3 cm. long in pictus 
and subcinereus very much inflated (somewhat so in scalaris), 
with cross section about round (deltoid-ovate in scalaris), tip 
but little flattened (decidedly so in insularis), reflexed, almost 
trasiucent and very thin, firm in subcinereus and scalaris, on 
a minute stipe shorter than calyx and mostly jointed to it. 
Mostly annuals, weak or low plants, erect. 
A2BC. Annuals or winter annuals with very thin small racemose 
flowers, and low and spreading habit. Pods seemingly sessile
