A2B. Calyx short-cylindrical to almost campanuiate, teeth shorter 

 than the tube and mostly very short. Pods inclined to be larger 

 above and tapering into a long and filiform stipe at base, acute 

 at tip, very flat, about straight, 2-4 cm. long exclusive of th« 

 stipe, smooth. Flowers fully 1 cm. long. Leaflets distant, 

 1-2 cm. long, mostly acute and mostly linear. Peduncles elon- 

 gated a-nd subterminal 



A2BC. Flowers bright pink-purple, few. Stipules connate below. 

 Calyx teeth rather narrow. Pods opening first at tip. 

 3 CoKonl. 



A2B2C. Flowers ochroleucous or white, rather many. Calyx teeth 

 broad and mostly deltoid. Lower rib of the pod a mere linij 

 and inconspicuous. Stipes capillary. Pecl»jncles slender. 

 Pedicels slender, 2-4 times as long as bracts. Stems erect and 

 branching above, 2-3 ft, high. Leaflets 7-15 pairs, long-petiolu- 

 late. Upper leaves about sessile, the lower short-petioled, 

 spreading. Leaf rachis conspicuously tapering. 

 4 stenophyllus. 



5 Antiselli. 



2A. Pods not papery, rather rigid and almost leathery, rarely nar- 

 rower below than at tip, with sutures not conspicuously thicken- 

 ed, though evident and acuminate at tip. 

 2AB. Pods conspicuously stipitate. This group seems to connect 

 with the Podo-sclerocarpi, but is equally as near as the Homalobi 

 2ABC. Pods erect, conspicuously laterally flattened. Leaflets 

 nearly round, leathery, broadly cuneate below. Whole plant 

 smooth except for a few hairs on the calyx. 



6 porrectus. 



2AB2C. Pods long-stipitste, acuminate at both ends, linear, re- 

 flexed or widely spreading, mottled, the body 3-4 cm. long, 

 3-5 mm. wide, much laterally flattened, the ventral suture 

 the more arched and ood inclined to be recurved. Rather 

 straggling, slender plants 2-3 ft. long. Pedicels not twisted 

 though pods appear upside down. Inversi. 



7 Californicus. 



8 inversus. 



2A2B. Pods narrow, mostly sessile or with a minute stipe, mostly 

 linear or oblanceolate, sharply acute, ending in a filiform tip, 

 when young flat and knife-like and inclined to be larger above 

 (not so in Episcopus and normally in most forms of junceus), 

 when mature flat at tio and also flat at base (except in forms 

 of Junceus), the middle section being obovate elliptical (flat 

 in Episcopus) or rarelv cordate when sulcate in one form of 

 of campestris, mostly narrowed into the calyx, tip nearly always 

 declined, the ventral suture normally more arched (convex) than 

 dorsal at least toward the tip cf pod but seeming less so because 

 of the twisted pedicel which brings the pod wrong side up, rare- 

 ly in forms of junceus the pods are falcate upwards and with 

 ventral suture concave. Pods rgco-iose, widely spreading or 

 reflexed smooth when mature. Flowers capitate rarely, mostly 

 racemose, widely spreading or reflexed, rather greenish white 

 with the keel purple-tipped and sometimes the banner, short 

 and stubby, rarely 1 cm. long, Bracts short and sharp, rarely 

 as long as pedicels in fruit. Keel greatly incurved. Slender 

 plants growing in tufts from slender crown-branchpes.„„^<»om 

 tap root, mostly low and weak. Leaves narrow with rather 

 distant leaflets and with t^"? slender petiole mostly as long as 

 the rachis, or the leaflets rudimentnr/ or absent f.'-om the rjsh- 

 like rachis. Campestres.
