Clematis. RANUNCULACEiE. 9 



Carolina, Walter ex Pursh. Flowers small, white. Sepals linear, lonn;er 

 than the stamens. Tails of the caqiels very Ions:, feathered. Pursh. — De- 

 scribed by Pursh from specimens in Walter's herbarium. It seems to be 

 ti mere variety of C. Virginiana. 



8. C. li^usticifolia (Nutt. ! rass.) : " plant somewhat pubescent ; flowers 

 in paniculate corymbs, dicccious ; leaves pinnate and ternate ; leaflets ol)- 

 iong, acute, mostly somewhat lanceolate-cuneate, incisely toothed and tri- 

 fid ; petals and stamens equal in length ; carpels with long plumose tails. 

 — C. Virginiana, Hook. Ji. Bo7\-Ain. 1. p. 1. (in part). 



"/?. hrevifolia: leaves smoother, shorter and broader. 



"Plains of the Rocky Mountains, in open and in bushy places, near 

 streams, ft. in the Blue Mountains and on the borders of the ()regon. — 

 Very similar to C. Virginiana, but the leaves are mostly 6-foliolate, and al- 

 most lucidly coriaceous ; they are also much smaller, and in the var. a. 

 much narrower and longer. The tails of the carpels are also longer, and 

 more densely plumose in C. Virginiana. Flowers white and fragrant." 

 Nutt. 



9. C. Drummondii : flowers in paniculate corymbs, dioecious ; leaves 

 pinnate, silky-villous beneath, sparingly hirsute on the upper surface; leaf- 

 lets rhombic-ovate, incisely 3-lobed, the lobes acute ; sepals 4, oblong ; car- 

 pels villous, with very long capillary plumose tails. 



Texas, JJrummond ! — Stem slender, angular, somewhat hairy. Leaflets 

 mostly 5, about an inch long; the lateral lobes sometimes a little toothed. 

 Panicles about as long as the leaves, trichotomously divided. Sei)als wliite, 

 villous externally. Tails of the carpels very slender, nrore than two inches 

 in length, densely plumose. — Seems to be nearly allied to C. sericea of Central 

 America. It is also closely related to C. Virginiana. 



10. C. pjxii0ora (Nutt. \mss.): "smooth; leaves pinnate and ternate ; 

 leaflets obovate, obtuse, mostly 3-lobed, the lobes short ; flowers axillary, ap- 

 proximated, on short peduncles ; carpels smooth, with slender plumose tails. 



'^'ear the sea-coast of St. Diego, Upper California. — Climbing, but in- 

 clined to grow erect and bushy. Leaflets about an inch long and nearly as 

 broad, commonly dilated and 3-lobed ; petioles slightly pubescent. Pedun- 

 cles slender, and so near together as to appear aggregated. Flower not 

 seen. Carpels compressed ; the tail rather sparingly pQose-plumose." Nutt. 



11. C. lasiantha (Nutt.! mss.) : "pubescent; leaves ternate, broadly 

 ovate, obtusely cuneiform at the base ; leaflets incisely toothed, the terminal 

 one 3-lobed or trifid; flowers dioecious, solitary, on 2-leaved aggregated 

 branchlets ; sepals cuneate-oblong, spreading, villous on both surfaces ; car- 

 pels 



" With the preceding. — Leaflets an inch and a half long and about an 

 inch broad, almost villous beneath. Peduncles about three inches long, with 

 a pair of entire or toothed leaflets near the base. Flowers more than an inch 

 in diameter. Allied to C. orientale, but very distinct." Nutt. 



12. C. Viorna (Linn.): peduncles l-(rarely 2-3-) flowered ; sepals con- 

 nivent, thick, acuminate, reflexed at the apex ; leaves glabrous, membrana- 

 ceous, pinnate ; leaflets entire or 3-parted, ovate or oblong ; floral leaves en- 

 tire; carpels with long plumose tails.— W7//d sp. 2. p. 1288; Michx.\ ft. 1. 

 p. 318 ; Pursh! ft. 2. p. 385; Ell. sk. 2. p. 46; DC. prodr. 1. p. 7. C. 

 cordata, Bot. mag. t. 1816. 



Pennsylvania ! to Georgia ! and west to Kentucky ! May-Aug.— Leaves 

 pinnate: the two lowest segments often ternate ; "leaflets variable, mostly 

 acute, but sometimes obtuse. Peduncles axillary or terminal. Flower nod- 

 ding. Sepals coria»ebus, about an inch long, purple. Tails of the carpels 

 an inch and a half loi^, very plumose.
