pods without mucilaginous matter. This is quite common from the 
Wasatch Mountains’ to the western side of the Fish Spring Moun- 
tains, in Western Utah. West of there it is replaced by the next. 
It grows on gravelly hillsides. Pods purple spotted, thin and acute 
at each end. 
ASTRAGALUS BECKWITHII Torrey var. PURPUREUS. This plant, 
though it has all the marks of a good species, I do not feel like de- 
scribing as such till one or two things can be settled about it. Ban- 
ner purple, fiddle shaped, notched at top and broad at base, arched 
to nearly 90° and abruptly, white spot fan shaped and streaked 
deeply (to the base on the sides) with purple; sulcus ¥{ circle, ex- 
cept at the base, where it is semicircular, fusiform longitudinally; 
the purple streaks on the white spot are united at the base of the 
sulcus into a purple ring; the banner is bent at a point 2 lines be- 
yond the calyx teeth; wings obliquely ovate, rounded and obtuse at 
the apex, white from the tip to the keel and purplish beyond, up- 
wardly curved, 2 lines wide, 2 lines longer than keel; keel purple 
and very dark at tip, incurved 100° to base, blunt. Whole flower 
curved upwards, purple and never yellowish except when old. The 
other characters are leaflets 6 to 12 pairs, inclined to be diamond 
shaped, 6 lines or less long and over % as wide, rounded, truncate 
or retuse; stems ascending, angled as well as petioles and pe- 
duncles; flowers 6 to 10, at first in a head but lengthening to 1 to 2 
inches; penduncles shorter than the leaves; calyx as in the type, 
yellowish but with nigrescent hairs, tube 2 lines by 1%; teeth 1 
line more, subulate from a broad base, almost black; calyx spread- 
ing in flower and reflexed in fruit, but the stipe (equaling the teeth) 
bent upwards so that the pod is nearly vertical; pod acuminate at 
each end, inwardly curved ventrally, so as to make % to % the arc 
of a circle, 144 to 1 inch long, dorsal sulcus intruded % line, sulcate 
dorsally always at base, but not in the upper half when pod is much 
curved; when nearly straight and only acute at base and apex 
(which occasionally occurs) the pod is deeply sulcate, finely cor- 
rugated, cartilaginous, filled with a mucilaginous pulp when imma- 
ture; seeds flattish, nearly round, with a prominent hilum, 1 line 
wide. Fully mature pods are usually obcompressed so as to be 
flat, while at the ventral suture they are compressed, making the 
cross section T shaped, usually purple spotted. This differs from
