4 BOTANY. 



toothed. Var. Ochotensis, with linear antheriferous petals. — A trailing 

 woody-stemmed plant, 6' high, glabrous but for a few scattered silky hairs, 

 C. alpina and Sibirica, Mill., and Ochotensis, Poir., differ only in the degree of 

 development of the petals. Eocky 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 veeticillaeis, DC. On wooded mountain sides; a low 

 climber. From North Carohna to Maine, along the great lakes, northward 

 to latitude 54°, and west to the Eocky Mountains and "Washington Territory ; 

 also found in Northern 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. & 

 Gr., having rather small, more narrowly sepaled flowers, but it scarcely de- 

 serves to rank as a distinct variety. (4.) 



Thalicteum alpinum, L. Stem simple, nearly naked ; leaves 2-3-ternate ; 

 leaflets 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 the mostly radical leaves ; slightly pubescent. Islands of the 

 Grulf of St. Lawrence ; Grreenland ; Behring Strait ; and Eocky Mountains 

 of Colorado. Found in the Clover Mountains, Nevada, on a damp grassy 

 bank, at an altitude of 10,000 feet, with Vaccinium ccespitosum, and Salix 

 reticulata ; in fruit, September. (5.) 



Thalicteum spaesifloeum, Turcz. {T. clavatum, Hook., not of DC.) 

 1-2° high; panicle loosely few-flowered, long pedicelled; flowers perfect; 

 filaments clavate ; anthers elUptical, pointless ; ovaries 8-10 ; carpels com- 

 pressed, dimidiate, not striate, short-stipitate, thrice longer than the persistent 

 style; upper leaves sessile, 2-3-ternate; leaflets often small. — Collected by 

 Dr. Eichardson in the Saskatchewan region, latitude 57°, and by Dr. Parry 

 and others, in Colorado. Found in the Uinta Mountains, only in Provo 

 Eiver Canon, at an altitude of 7,000 feet ; July. Identical with Siberian 

 specimens. (6.) 



Thalicteum Fendleei, Eng. PI. Fendl, p. 5. Dioecious, glabrous ; 

 leaves petioled or the uppermost sessile ; filaments capillary ; anthers linear, 

 mucronate ; carpels ovate, compressed, oblique, sharp-edged, with 4-6 strong 

 lateral ribs, tapering into the long persistent style; sessile or shortly stipitate.—
