 middle elevations. Hall & Harbour, 2; Dr. Smith; Meehan; Porter;

CLEMATIS SCOTTIT, Porter (n. sp.) More or less villous, with soft, 

 spreading hairs; bushy, branching from a suffrutescent base, branches 

 erect, 9'-18', not climbing; leaves opposite on rather long petioles, pin- 

 nate; leaflets five pairs, ovate or lanceolate, acute or acuminate, petiolu- 

 late, strongly veined beneath, lower ones often 2-3 cleft; flowers axillary 

 and terminal, nodding, peduncles 3'-6'; sepals 4, ovate, with reflexed 

 summits nearly 1' long, dark or brownish purple, thickish but not 

 leathery as in C. Viorna, more or less tomentose on the outside; carpels 

 silky pubescent, with densely plumose tails I'-IJ' in length. Named for 

 Hon. John Scott, who collected it in 1872, at Soda Springs, 35 miles 

 w^est of Canon City. Brandegee, Fremont County, in fruit. Redfield. 



CLEMATIS LIGKJSTICIFOLIA, Nutt. Climbing, somewhat pubescent, 

 flowers white, in paniculate corymbs, direcious ; leaves pinnate and ter-

 somewhat lanceolate-cuiieate, incisely toothed and tritid; petals and 

 stamens equal in length ; carpels with long plumose tails. Common along 

 water-courses, at the base of the foot-hills, and ascending the ravines, 

 climbing over bushes.and producing a great abundance of white flowers.
