somewhat flattened or sulcate ventrally, i celled; seeds not round; 

 calvx erect in fruit; pods erect or spreading. It is i 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 be a 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 oi 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 i to 2 lines long and 

 like a normal wing, the upper lobe is yz 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 June 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,
