scarcely enlarged below; akenes usually obtuse at apex, 

 never acuminate ; sparsely pubescent below, much pubes- 

 cent above; tail 2 long; mature peduncles about 5' long; 

 leaflets thin, shortly acuminate. 



Clematis verticillaris DC. has coarsely and sparsely 

 dentate, ovate, shortly acuminate leaflets, which are often 

 trifid ; fruiting peduncles 2-3' long, reflexed; akenes 

 I— 1}4" long, obovate, with a broad and flat border, which 

 tapers abruptly into a flat wide tail, which gradually nar- 

 rows upward; akenes nearly equally hairy throughout, 

 and sparsely so, nearly twice the size of those of thevar. 

 Columbiana. 



Clematis Douglasii var. Bigelovii (Torrey, Pac. R. R. 

 Rep., 4, 61). 



Clematis Bigelovii Torrey 1. c. 



I can find no characters which separate this from C. 

 Douglasii. Palmer's specimen from New Mexico has 

 the long peduncle and flower of C. Douglasii, has three 

 distinct pairs of leaflets besides the terminal one; the 

 lower pairs are again j-parted, and the divisions stalked 

 (lateral stalks 2" and terminal one 6" long), making the 

 leaf 2-ternate, the leaflets are again cut-toothed or parted 

 into acute segments, whose general outline is ovate to lan- 

 ceolate, 6-12" long; petioles of the main pairs of leaflets 

 1' long; leaflets nearly glabrous ; petioles, etc., decidedly 

 pubescent; inner sepals woolly. 



Newberry's specimen from McComb's Expedition has 

 leaflets of Douglasii, but broader, the fruit is that of 

 Douglasii. 



Lemmon's specimen from Arizona has filiform seg- 

 ments, but in other respects is C. Douglasii. 



Shufeldt's specimen from Fort Wingate, New Mexico, 

 has oblong-ovate leaflets, 6" or less long, mostly entire, 

 shortly acute, and giving a wholly different appearance,
