keel, 1 mm. shorter than banner. Keel claw enlarged just above 
the calyx so as to make a hollow in the banner, with decided hump 
at base, purple-tipped, the base a little arched, then sharply rounded 
to erect, the blade forming about a half circle, acutish to very obtuse, 
4 mm. long, 3 mm. high. Calyx tube campanulate, 3-4 mm. long, cleft 
deeper above, with rounded sinuses, oblique at base and inserted on 
the lower corner, silvery to nigrescent and densely pubescent, teeth tri- 
angular, rather lax, about half as long as tube. Bracts ovate, about 1 
mm. long. Pedicels 1-3 mm. long in fruit. Peduncles filiform, erect 
in flower, mostiy flat on the ground in fruit, from 1-15 em. long, 
in the diminutive forms concealed in the leaves, in more robust 
- ones 4 times as long as leaves, 2-6 flowered, scapose. Leaves 2-10 
em. long, with filiform petiole twice as long as rachis, fascicled on 
the very short crowns. Leaflets 1-3 pairs, oblong to obovate, 2-10 
mm. long, silvery on both sides, usually acute, thick, flat, on the 
lowest leaves often there is but one obovate leaflet. Stipules large, 
deltoid, imbricated mostly, 5-5 mm. long. Stems reduced to many 
short crowns in dense but small mats crowning a long, slender, 
‘erect root. Growing on gravelly mesas but well drained and on 
rocky ridges from the foothills to 10,500 ft. alt. on Mt. Ibapah, 
Utah. Common from the bad lands of western Wyoming to Poca- 
tello, Idaho, and Glenwood Springs, Colorado, to the Mogollons and 
the Sierras. Lower and Middle Temperate life zones. Blooming in 
spring. A very variable plant. ‘ihe starved plants are as dense 
and short as a czspitose phlox. Those growing in the shade are 
long-petioled and long peduncled. The pods vary from about as 
long as calyx and teeth to an inch long.
