PODO-SCLEROCARPI. 8. 



Pods fleshy when fresh, cartilagious or with thick woody 

 Avails ■when dry (coriaceous in some forms of Toaniis), 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 cm. long, strongly cross nerved, never 

 linear, rarely less than 1 cm. wide, never more than puberulent, 

 not explanate, very strongly beaked, racemose. Flovv-ers 1-2 

 cm. long, large, mostly white, with elongated banner and 

 wings. Bracts short and triangular, inconsj^icuous, 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, hyaliue 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-ce!led, 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 b.-5se 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 winqs 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. 

 Pofls erect. 07 Toaniis. 



Pods reflexed. 9S Kafviensis. 



ABC2D. Pods not r'ecidedly laterally compresred, cv^l 'o oblong 

 straight, scarcely at all oblique, cross section nearly round, 

 abruptly contracted into a stout conical beak, both statures 

 arched, the ventral a trifle the more, sometimes a little dor- 

 sally, both sutures very thick, about 1.5 cm. long.. Flowers 

 many 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
