toothed. Var. Ochotensis, with Unear aiitheriferoiis petals. — A trailing 
woody-stemmed plant, 6' high, glabrous but for a few scattered silky hairs. 
C. alpina and Siblrica, Mill., and Ochotensis, Poir., differ only in the degree of 
development of the petals. Rocky Mountains of Colorado and New Mexico. 
In Utah it was seen only in the Wahsatch Mountains, (Cottonwood Canon,) 
at an altitude of 8-9,000 feet ; July, in flower and fruit. (3.) 
Clematis verticillaris, DC. On wooded mountain sides; a low 
climber. From North Carolina to Maine, along the great lakes, northward 
to latitude 54°, and west to the Rocky Mountains and Washington Territory ; 
also found in Nortliern California. Not rare in the Wahsatch and Uinta 
Mountains, Utah, at an altitude of 7-9,000 feet ; in flower and fruit, July to 
August. The specimens accord with the description of C. Columbiana, T. & 
G., having rather small, more narrowly sepaled flowers, but it scarcely de- 
serves to rank as a distinct variety. (4.) 
Thalictrum alpinum, L. Stem simple, nearly naked ; leaves 2-3-ternate; 
hndlets roundish, somewhat lobed, crenately toothed ; flowers perfect, in a 
simple raceme, nodding; filaments filiform ; anthers oblong-linear; carpels 
few, ovate, sessile ; stigmas thick and pubescent. — Low, stems 2-8' high, 
much exceeding tlic mostly radical leaves ; slightly pubescent. Islands of the 
Gulf of St. Lawrence ; Greenland ; Behring Strait ; and Rocky Mountains 
of Colorado. Found in the Clover Mountains, Nevada, on a damp grassy 
bank, at an altitude of 10,000 feet, with Vaccinium ccespitosu?n, and Salix 
reticulata; in fruit, Sej)tember. (5.) 
Thalictrum sparsiflorum, Turcz. ( T. clavatum, Hook., not of D C.) 
1-2^ high; panicle loosely fcw-Howered, long pedicelled; flowers perfect; 
filauKnits clavate; anthers elliptical, pointless ; ovaries 8-10; carpels com-

styk'; ui>j)or leaves s(\^sile, 2-3-ternate; leaflets often small. — Collected by 
Dr. Richardson in the Saskatchewan region, latitude 57°, and by Dr. Parry 
and others in Colorado. Found in the Uinta Mountains, only in Provo 
River Canon, at an aUitude of 7,000 feet ; July. Identical with Siberian

leaves petiok^d or the uppermost sessile; filaments capillary; anthers linear,
