Alpinı, 131 
ALPINI 6. 
Pods papery, variously inflated, rarely large, on slender 
pedicels stipitate and pendent (erect in the first group), rather 
few-seeded in the middle, opening throughout the ventral sut- 
ure; with ventral suture the more arched in young pods or 
when rarely coneave in A: andinus in mature pods the tip 
is declined; with dorsal suture a mere thickened edge within 
or a little produced as a papery partial partition, the body 
rather oblique but nearly straight. Flowers small (about 1.5 
em. long in A, Gormani and the alpinus group). Stipules 
green and conspicuous (hyaline in A. Gormani), veiny, large 
or foliose, not connate (rarely so in A. andinus, free in A. Gor- 
mani), longer above on the stems, very broad near the root. 
Stem leaves fully or almost sessile (short-petioled in the A. al- 
pinus group), with several pairs of thin, flat, rather narrow, 
green, and mostly obtuse leaflets. Plants blooming in sum- 
mer and growing in high and cold mountains and mountain 
valleys. Phaca. ; 
KEY 
^. Pods apparently sessile. Flowers in long racemes. Bracts tri- 
angular-subulate with thread-like tips, 3-7 mm. long. Leaves about 
sessile, about 1 dm. long, with 6.8 pairs of nearly linear leaflets 
cuneate at base and about 2 cm. lona and rarely 5 mm. wide, 
and long-petiolulate. Peduncles elongated and strict, much longer 
than the leaves, and with rachis about half the peduncle, 
Pods erect and appressed. Arctic. | 84 Gormani. 
Pods pendent. Sabulis ' 85 elegans. 
2A. Pods conspicuously stipitate and pendent, appearing almost sessile 
in some cases in A. Labradoricus var. occidentalis. 
2AB. Stipules not very large nor leaf-like, acuminate above, Bracts 
' small, and acuminate. Peduncles longer than the leaves. Flow- 
ers with purple-tipped keel, and mostly purple tinged above, not 
over 1 cm. long. Young pods inclined to be nigrescent. Calyx 
teeth triangular to subulate often as long as tube. Pods dis- 
tinctly laterally flattened when mature, not sulcate or only 
slightly so, the dorsal suture intruded as a partial partition, but 
rarely 1 mm. high. The ventral suture greatly arched and the 
dorsal about straight. Flowers in long racemes (except in A. 
Cottoni). A. arcticus and oroboides are near this group. 
Pods narrow, 1-2 cm. long. Flowers stubby. Leaflets broad and not 
congested. Leaves 4-7 cm. long. Pubescence almost none,
