HOMALOBI. 
Pods. wholly 1-celled, with rib-like sutures which are 
neither conspicuously raised as sharp edges nor intruded 
as partitions, splitting along both sutures from the tip, (from 
the base in A. stenophyllus), rarely suleate dorsally, not at 
all ventrally, with walls papery to thin-coriaceous, rarely a 
little inflated, with body linear to oblanceolate or rarely nar- 
rowly oblong to half-oval. Flowers racemose, rarely capi- 
tate. Perennials (A. quinqueflorus is annual.) 
BES” The synonymy in the text is much abbreviated to avoid packing the de- 
scriptions with useless matter. Complete synonymy is given in the Index 
where all names are found under the recognized species to which they belong. 
Abbreviated cross references are given under generic synonyms simply to aid 
in finding the correct name. 
Key 
A. Pods papery, reflexed, with sutures thicker than the walls (not 
evidently so in the stenophyllus group), not sulcate, normally 
completely laterally flattened when immature and mostly so when 
ripe, abruptly apiculate, with suture the more arched except rarely 
in A. stenophyllus, narrowed below. Pedicels not twisted. 
AB. Calyx almost turbinate, 1-2 mm. long, the slender teeth at 
least half as long as but little longer than tube. Sitipules con- 
spicuousiy connate. Foliage inclined to blacken on drying. 
Weak, much branched, and very slender plants with small and 
purplish (rarely whitish) flowers, Leaflets long-petiolulate acute 
at base and. narrowed. Pods almost sessile or on a stipe not 
much longer than calyx, narrowly oblong to half-oval, with the 
sutures prominent. : 
ABC. Calyx teeth decidedly shorter than the tube. Ribs of pods 
conspicuous. Peduncles elongated and subterminal and with .- 
the rachis often a foot long. Leaflets distant, mostly folded 
and rather thick, but really oblong, seemingly linear. Leaves 
never sessile, Perennials of dry and open mountain slopes in:

2 tenellus. : 
AB2C. Calyx teeth longer than the tube and unequal, tube about. 
2 mm. long. Pods short-oblong to half-oval, ashy, inflated and . 
cross-section deltcid-ovate, not 1 cm. long (about 8 mm.) 3-5 
mm. hiah, about sessile. Ventral suture nearly straight, the 
dorsal much arched. Flowers purplish, ascending, 5-7 mm. 
long, in short racemes on short and filiform peduncles which 
are much shorter than the leaves and solitary and axillary 
nearly throughout. Leaves all petioled, rarely 6 cm. long. 
Leaflets nearly linear and acutish at both ends to narrowly 
elliptical and obtuse, thin, nearly 2 cm. long. Pubescence 
ashy throughout. A. pauciflorus and miser might be sought. 
here as they are near relatives but because of much inflated 
pods and ventral suture being less arched they are placed in —
