PODO-SCLEROCARPI. 8. 
Pods fleshy when fresh, cartilagious or with thick woody 
walls when dry (coriaceous in some forms of Toanus), not 
jointed to calyx or stipe, neither suture evident when 
fresh but both conspicuous, thick and raised when dry, little 
if at all inflated, 1-4 em. long, strongly cross nerved, never 
linear, rarely less than 1 em. wide, never more than puberulent, 
not explanate, very strongly beaked, racemose. Flowers 1-2 
em. long, large, mostly white, with elongated banner and 
wings. Bracts short and triangular, inconspicuous, shorter 
than the mostly short and the stout fruiting pedicels. Pods 
and flowers mostly reflexed. Stems green and rush-like, and 
with the leaves, and petioles much alike. Stipules rigid and 
small, deltoid at base, reflexed above and green, hyaline be- 
low. Leaflets distant, fleshy, mostly almost filiform and thick, 
never more than linear, often obscurely if at all jointed 
to the rachis. Plants of the valleys and alkaline springs or in 
alkaline soil, perennials 
KEY 
A. Pods wholly 1-celled, the dorsal suture a trifle intruded in A. pter:car- 
pus. 
AB. Pods sessile at least when fresh, stipe if any when dry very 
short and thick. 
ABC. Pods opening nearly equally at both sutures from the tip 
to the middle, rarely sulcate, about 1.5 cm. long, laterally if at 
all compressed, about straight. Stipules hyaline and connate 
toward the base of the stems, green and free above. Pectinati. 
ABCD. Pods oblong to lanceolate, smooth, distant, full of pulp, 
not inflated, racemose on long and terminal peduncles, with 
beak flat, elongated and prow-like., Flowers purple, large 
and elongated, about 2 cm. long, with long wings and ban- 
ner and purple-tipped keel. leaflets none to 5 pairs, fili- 
form except some of the lowest, jointed to the rachis and 
like it. Upper leaflets simple and rarely at all enlarged at - 
tip.. Tall and slender and densely tufted plants. 
Pads erect. 97 Toanus. 
Pods reflexed. 98 Rafelensis. 
ABC2D. Fods not decidedly laterally compressed, oval to oblong 
straight, scarcely at all oblique, cross section nearly round, 
abruptly contracted into a stout conical beak, both sutures 
arched, the ventral a trifle the more, sometimes a little dor- 
sally, both sutures very thick, about 1.5 cm. long.. Flowers 
manv in short and dense spikes, horizontal to a little re- 
flexed, mostly white, 1-1.5 cm. long, straight, with exserted 
claws, blades very long. Banner elliptical-oblanceolate, 
sides much reflexed, ascending in a gentle curve to nearly
