144 roao-scıerocarpi. 
A2B. Pods conspicuously stipitate, with stipe longer than calyx and 
recurved, and the body very falcate upwards, acuminate at both 
ends but most at base, opening first at base and through the 
stipe, much laterally flatened at tip and base, conspicuously ob- 
compressed in the middle when mature and corrugated finely, 
not hairy, rounded on the sides but appearing almost as if 
winged at the thick and raised sutures when dry, and cartila- 
ginous, elongated-lunate, 2-5 cm. long including the stipe. Leaf- 
lets several pairs, narrow, all jointed to rachis by slender petio- 
lules, obtuse. Flowers 1-1.5 cm. long, the petals not elongated 
nor stubby, ascending. Calyx campanulate to short-cylindric, 
about 5 mm. long, hyaline and black-hairy, the teeth shorter 
than the tube.  Pedicels short and stout, recurved in fruit. 
Bracts ovate to triangular, 1-2 mm. long, about as long as pedi- 
cels. Banner arched 45 to 80 degrees remote from calyx tip, 
the blade 9 mm. long and with sides reflexed. Wings nar- 
rowly oblong, arched 15 to 20 degrees, 2 mm. shorter than ban- 
ner. Keel wide, the tip rounded and very obtuse, straight, in- 
curved at tip to 80 to 100 degrees. Stipules small, green, 
Stems tufted from a woody root, about 2 ft. high, rather flexuous, 
with internodes less than half as long as the leaves, somewhat 
ashy throughout. Plants of the upper edge of the Lower Tem- 
perate life zone, in dry places, blooming in early summer. 
Sclerocarpí. 
Pods narrow, acuminate at both ends. 104 sclerocarpus. 
2A. Pods either wholly or partly 2-celled by the íntrusion of the 
dorsal and ventral sutures but partition never complete by the 
union of the sutures, with the tip 1-celled, mostly slightly in- 
flated, 1.54 cm. long, 5-7 mm, high, 7-10 mm. wide, inclined to 
be a little obcompressed except in A. pachypus, smooth, very 
fleshy and nearly round when fresh, with. firmer inner wall, 
the pulp about 1 mm, thick, the cavity filled with pulpy fluid when 
green, coarsely wrinkled or cross-ringed and woody when dry, 
never reflexed, oblique, oblong, a little arched ‘by the ventral 
suture being concave and raised, abruptly contracted into a stout 
conical-subulate beak 2-5 mm. long, with sutures prominent ex- 
ternally, opening along the ventral suture and first at tip. 
Flowers and pods ascending, the former rather narrow, loosely 
racemose, widely spreading, rather few on the upper third of 
peduncle, about 2 cm. long. Banner oblong-ovate, gently arched 
to 60 to 80 degrees at calyx tips, with sides reflexed to midrib 
most below, with tip notched. Wings oblong, oblique, 1 cm, long, 
obtuse, concave to keel, with tips touching beyond it, longer than 
keel and much shorter than banner. Keel blade about 3 mm. 
Petals thin and with exserted claws. Calyx tube narrowed be- 
low to the lower corner where it is attached by a slight angle 
.to the pedicel, somewhat fleshy below, cleft deeper above, later- 
ally flattened; teeth triangular-subulate. Bracts about 2-3 mm. 
‚long, triangular-subulate to ovate. Pedicels in fruit stout and 
woody, about 3 mm. long. Peduncles stout and strict, 1.5-3 dm. 
long including the floral rachis; twice as long as the leaves. Mid- 
die leaves the longest. Leaflets all jointed to petiole, thick and 
leathery and fleshy, at least some of them linear. Proper peti- 
oles short but rachis of leaf and tapering and 1-1.5 dm. long. 
Stems straggling upward, not very stout, sulcate, branched below. 
1-2 feet high, flexuous. Internodes much shorter than the leaves. 
Stipules rigid, green, reflexed, small. Pubescence minute, ashy. 
Alkali-loving plants of the Lower Temperate life zone. Pachypodes. 
2AB. Pods splitting to the middle from the tip along both sutures, 
sessile when fresh (the drying of the flesh makes it seem a 
little stipitate.) Flowers purple-tipped, in rather long and very
