RANUNCULACE^. 



Clematis Douglasii, Hook.^ Stem herbaceous, erect, 1-2° high, 

 simple, 1-flowered; leaves 2-3-pinnatifid, (or the lower ones more simple,) 

 the segments linear or linear-lanceolate, both stem and leaves more or 

 less hairy ; flower nodding, the naked peduncle erect and elongated in fruit ; 

 sepals thick, woolly at the apex, more or less spreading, deep brownish- 

 purple, paler externally. — The specimens resemble those from Oregon de- 

 scribed by Nuttall under the name of C. Wyethii, differing from the form 

 figured by Hooker and of the eastern Rocky Mountain collections only in the 

 broader divisions of the leaves. In the mountains from Washington 

 Territory to Colorado. Found in the Wahsatch and Uintas, Utah, at an 

 altitude of 6-7,000 feet ; July, in flower and fruit. (1.)^ 



Clematis ligusticifolia, Nutt. Climbing, somewhat pubescent; flowers 

 white, dioecious, in paniculate corymbs ; leaves pinnate and ternate, (mostly 

 5-foliolate,) the coriaceous leaflets usually oblong, lanceolate, more or less 

 laciniately toothed and trifid ; petals and stamens equal. Var. brevifolia, 

 T. & Gr. With nearly smooth broadly ovate subcordate 3-lobed leaflets. — On 

 the banks of mountain streams from Washington Territory to the Saskatche- 

 wan, and southward to Lower California and New Mexico. Frequent in tbe 

 lower cartons of the West Humboldt Mountains and found in a single locality 

 in the East Humboldt range, Nevada — the broad-leaved variety only; altitude, 

 6-6,000 feet; August^October. An approach to the typical form was also 

 found at City of Rocks, in Southeastern Idaho. (2.) 



Clematis alpina, Mill. DC. Prodr. 1. 10. Leaves bi-ternately divided ;

' A large portion of the described species up to the end of the Compositce are to be found in Torrey 

 and Gray's Flora of North America, and a general reference to that work for the synonymy, &o., is to be 

 understood. In case of other species not occurring in the Flora, express reference is usually made simply 

 to De Candolle's Prodromua ; or to still later revisions, or for more recent species, to the publications in 

 which they are described.
