A2B. Calyx short-cylindrical to almost campanulate, 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 the 
stipe, smooth. Flowers fully 1 cm. long. Leaflets distant, 
1-2 cm. long, mostly acute and mostly linear. Peduncles elon- 
gated and subterminal, 
A2BC. Flowers bright pifik-purple, few. Stipules connate below. 
Calyx teeth rather narrow. Pods opening first at tip. 
3 Coltoni, 
A2B2C. Flowers ochroleucous or white, rather many. Calyx teeth 
broad and mostly deltoid. Lower rib of the pod a mere line 
and inconspicuaus. Stipes capillary. Peduncles 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 excent for a few hairs on the calyx. 
6 porrectus. 
2AB2C. Pods long-stipitate, 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 ‘tod 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 tin and also flat at base (except in forms 
of junceus), the middle section being obovate elliptical (flat 
in Episcopus) or rarely 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 
ventra| suture concave. Pods racemose, 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-branches from 
tap root, mostly low and weak. Leaves narrow with rather 
distant leaflets and with the slender petiole mostly as long as 
the rachis, or the leaflets rudimentary or absent from the rush- 
like rachis. Campestres. EN ein
