8 RANUNCULACE.E. Clemalis. 



C. Douglasii, Hook. A foot or two high, villous-pubesceut when young, glabrate, leafy : 

 stem and jietioles angled and striate : divisions and lobes of the leaves linear or lanceolate 

 (from half line to 3 or 4 lines broad) : peduncles sometimes slightly sometimes very much 

 surpassing the uppermost leaves : calyx an inch to inch and a half long, villous outside, 

 more or less glabrate in age, purple within : akenes pubescent : persistent styles slender, inch 

 long, very plumose. — Fl. Bor.-Am. i. 1, t. 1 ; Torr. & Gray, 1. c. 8. C. W_i/ethii, Nutt. 

 Journ. Acad. Pliilad. vii. 6 ; Torr. & Gray, 1. c. — Rocky Mountains from Montana, Idaho, 

 aud north of tlie Britisii boundary to Colorado and New Mexico, and west to Oregon and 

 Washington ; first coll. by iJuiu/las. Varies greatly in foliftge, in the degree and coarse- 

 ness or fineness of the dissection ; a southern form (S. Colorado aud N. New Mexico) with 

 very narrow leaflets most distinctly showing tortuous petioles, as if disposed to climb. The 

 broad-leaved extreme is 



Var. Scottii, Coulter. Leaves large, pinnate with some or all the divisions 3-5- 

 parted or 3-5-foliolate ; lobes or leaflets oblong- or ovate-lanceolate (4 or 5 lines wide by an 

 inch in length) ; some upper leaves with distinctly tortuous partial petioles. — Man. Rocky

 Colorado ;i first coll. by John Scott, and by Porter. Also Beaver Canon, Idaho, Watson. 



§ 3. AxKiGENE, DC. Flowers large, hermaphrodite, solitary on naked 

 peduncles : sepals much exceeding the stamens and pistils, spreading from the 

 base, thin, petaloid, margiuless : anthers short on long pubescent filaments : outer- 

 most stamens with more or less dilated filaments bearing inane anthers or none, 

 or some converted into " petals," rather petaloid staminodes : styles wholly per- 

 sistent, becoming long plumose carpel-tails: hali'-woody climbers (but ours low), 

 the shoots of the season from scaly buds, early flowering : leaves ternately com- 

 pound. — Atragene, L. (The verticillate appearance of the foliage on the flow- 

 ering shoots, which gives an inappropriate name to one of the sjiecies, comes 

 from the pair of leaves from the opjwsite axils arising close to the main axis.) 



C. verticillaris, DC. Leaves simply 3-foliolate, slender-petioled ; leaflets sleuder-petiolulate, 

 ovate, mostly acuminate, entire or sparingly dentate : sepals violet, inch or two long, oblong, 

 more or less acute : staminodes little longer than the fertile stamens, sometimes all linear 

 and more or less antheriferous, often outermost petaloid and spatulate. — Syst. i. 166; Hook.

 Minnesota, &c., aud south to Pennsylvania ; - fl. early spring. 



Var. Columbiana, Gray, n. var. Sepals " blue," ovate-lanceolate or narrow, soon 

 attenuate-acute or acuminate. — C. Columbiana, Torr. & Gray, 1. c. 11. C. alpina, var. occi- 

 dentalis, forma verticillaris, Kuntze, 1. c. 161. Atrayene Columbiana, Nutt. Journ. Acad. 

 Philad. vii. 7. — Rocky Mountains, N. Utah and north to lat. 58°, and west to Brit. 

 Columbia. (Cape Mendocino, lat. 40°, Douglas, ace. to Hook., probably a mistake.) 



C. alpina, Mill. Leaves twice ternate with ovate or ovate-lanceolate leaflets short-petiolu- 

 late and irregularly serrate or incised, or simply 3-foliolate with some or all the leaflets 2-3- 

 parted: staminodes in the Old World plant numerous and conspicuous, spatulate, and most 

 of them not at all antheriferous. — Diet. ed. 8, no. 9 ; Lam. Diet. ii. 44 ; DC. S}'st. i. 165.

Var. OCcidentalis, Gray. Spatulate and petaloid staminodes few and usually with 

 rudiment of anthers, or none, most or all of the dilated filaments linear and more or less 

 antheriferous. —Gray in Powell, Geol. Surv. Rep. Dakota (1880), 531. C. alpina, yav.
