somewhat flattened or sulcate ventrally, 1 celled; seeds not round; 
calyx erect in fruit; pods erect or spreading. It is 1 to 2 feet high, 
slender. It was collected in gravelly soil at about 5,000 feet altitude 
in Utah Valley, May 16, 1891. The leaflets are broadly lanceolate 
to oval, obtuse to emarginate, 3 to 6 lines long, 10 to 14 pairs. Hith- 
erto this has been supposed to bea southern species, but it has doubt- 
less been overlooked. 
ASTRAGALUS CALYcosus Torrey. This most interesting and 
badly named little species proves to be very common in all the ranges 
and hills west of the Wasatch Mountains, Utah. I have gathered it 
as far west as Humboldt, Nevada. Watson’s description in King’s 
Rep. is faulty also. Outline of banner oval, cleft a line deep, sides 
reflexed 100°, generally cream white but often purple; white spot 
broad, with cuneate sides to the middle where it widens again, broadly 
emarginate at apex; sulcus rectangular and broader than deep; wings 
very closely appressed to keel its full length, red purple to tip of 
keel, white beyond, deeply cleft, lower lobe 1 to 2 lines long and 
like a normal wing, the upper lobe is 4 wider, bent upward and in- 
ward till it touches the banner, both lobes narrowed and rounded at 
tip, usually from the cleft in the wings a long thread-like lobe arises 
and is nearly as long as the lobes; keel enlarged just above the calyx 
so as to make a hollow in the banner, with a decided hump near the 
base of keel; calyx notched deeper on the upper side; pod always 
arched when well developed, acute, 4 to 12 lines long, 2 celled, cross 
section ovate with a cordate base. Flowers erect or prostrate, pods 
narrowly oblong to linear, usually prostrate. It is not subalpine, 
as given by Watson; it is rare above 7,000 feet altitude and abounds 
in the valleys in gravelly soil, 5,000 to 7,000 feet altitude. © Torrey’s 
and Watson’s specimens seem to have been starved and with a 
poorly developed pod. 
ASTRAGALUS ATRATUS Watson var. STENOPHYLLUS n. var. 
Flowers smaller, leaves narrowly linear, short, minute, or wanting, 
and only the rachis present, always so in the upper leaves. 
This is No. 3840 of my sets of 1882. Collected PSE 14, 1882, at 
Palisade, Nevada, distributed as ‘‘Astragalus n. sp.’ 
ASTRAGALUS FILIPES Torrey. I believe there is an earlier name for 
this, but the old name will be the more familiar, and equally,as good 
for my purpose. Banner light cream colored, arched at right angle,
