to a right angle, erect part 1% lines long; keel surpassing calyx 
teeth 1% lines, incurved with the end straight, blunt, purple tipped; 
wings barely equaling the keel; pod oblong-linear, very shortly 
stipitate, 6 lines long, 1% lines wide, abruptly acute, both sutures 
prominent, flattened, apparently 1 celled, ventral suture arched, 
dorsal straight. 
June 23, 1891, Deep Creek Mountains, Western Utah, at 5,500 
feet altitude, among brush. The arching of the ventral suture of 
the above two species would suggest A. Rodédinsii, as that feature is 
very rare in Western plants, but the racemosely arranged esi 
peduncles and upper simple leaves are quite peculiar. 
ASTRAGALUS BiIGELoviI Gray. This in its flower is allied to 
the A. eriocarpus group along with A. amphioxys, and apparently 
should include the 4. AfZathewsiz Watson if there are no other good 
characters than those given by Watson. Banner arched 80° in a 
gentle curve, sides reflexed from calyx to tip 100°, the folded part 
being 1% lines wide at base and gradually reduced upwards so that 
the outline of the banner as one looks at it is oblong with straight 
sides and an enlargement at the base; sulcus a line deep and %4 
wide, broadly V shaped and continuous to the apex of banner, 
white spot occupying the whole of the sulcus and to within a line 
of the top of banner, narrowly oblong, emarginate, purple tinged 
below; base of banner, sides and tip rose purple, darker at the 
base; wings linear, 34 line wide, with a little lobelet on upper side 
near the base, obtuse, %4 line longer than keel, ascending 30°, dark 
rose purple at base and the upper two lines white, nearly flat with . 
the tips slightly incurved and so not quite vertical; keel dark purple- 
tipped, blunt and moderately incurved; banner rising 4 lines beyond 
the}tip of keel, in all 5 lines longer than tip of calyx lobes; calyx 
- pink, a little inflated, narrower with age and white, somewhat flat- 
tened, gibbous, ascending 45°; bracts 3 lines long and green. 
Taken from specimens gathered at Rincon, New Mexico, April 
15, 1892. It is also abundant in Eastern Utah. 
ASTRAGALUS GLAREOSUS Douglas. The plants which I have 
hitherto distributed as 4. glireosus are A. Chameleuce Gray, while 
this plant occurs sparingly throughout the Great Basin region of 
Utah, and is credited to Southern Idaho, and by Coulter to Wyo- 
ming also. I have hitherto considered it as 4. Chameleuce but it
