does it seem to vary much. It was found on April 27, 1900, near 
' Weiser, Idaho, considerably out of its usual range. Specimens 
gathered there show flowers 34 inch long, pink-purple; wings 
‘and keel same color; wings nearly straight, broadly linear, a lit- 
tle narrower toward the tip, a line wide, narrower than the keel 
and a line longer; banner ovate, sides reflexed to the sulcus 
throughout, the reflexed part fully 114 lines wide at base of ban- 
ner; sulcus V-shaped below and more shallow above; keel rounded 
in an are of a circle and very obtuse, blade 7 lines long and claw 
not exserted; white spot on banner large and purple-veined, ob- 
long; calyx thin, much compressed, lower side straight, upper 
side arched, inserted in line with the base; teeth linear-subulate, 
calyx 5-nerved, pink; young pods white-hairy. 
ASTRAGALUS PuRSHII Douglas var. TINCTUS Jones has the flow- 
ers almost exactly those of A. Ufahensis in color (a brilliant pink- 
purple); banner broadly elliptical; gently arched to 45° from the 
end of calyx tube; sulcus narrowly U-shaped for 4 lines in length, 
then widens to about ™% a line near the tip, and at the tip it van- 
ishes, it is very narrow at the base of blade; white spot spatu- 
late, a line wide at tip, comes within a line of the end of the 
blade; sides of banner reflexed for 2 lines in width in the middle 
on each side, all but the sulcus being reflexed; banner barely 
notched; wings broadly linear, concave to keel, narrowed at tip, 
almost straight, 1% lines wide at base, rounded at tip and obtuse, 
narrower than keel and exposing both its upper and lower sides; 
keel gently arched to go° from the base, dark-purple-tipped, very 
obtuse, straight, blade barely 3 lines long; calyx inflated (as is 
the case with the type and with 4. Utahensis also), much com- 
pressed laterally, red-lined, constricted at tip, 6 lines long, subu- 
late teeth 2 lines more, both upper and lower sides of calyx a lit- 
tle arched, a little fleshy and narrowed at the base; pods abruptly 
incurved at tip in the Idaho forms. 
ASTRAGALUS ARTEMISIARUM Jones. It seems like a very slim 
foundation to build a species on the color of the flowers and the 
presence or absence of pulp in the pod, which are the characters 
which separate this from 4. Beckwithii, but diligent search this
