CANADIAN EANUNCUL ACE, E. 33 



4. — Anemone occidentalis, Waison. 



"More or less silky-villous ; stems stout, -| to 1|- feet high, 1-flowered ; radical leaves 

 large, loug-petioled, biteriiate and pinnate, the lateral primary divisions nearly sessile, the 

 segments piunatifid with narrow laciuiateiy-toothed lobes ; involucral leaves similar, 

 nearly sessile, abont the middle of the stem ; sepals 6 or Y, six to nine lines long, white or 

 purplish at base ; receptaele conical, becoming mnch elongated, sometimes IJ in. long ; 

 acheues linear-oblong, the tails at length IJ in. long, reflexed." Watson. 



Mr. Watson points out (Proc. Am. Acad., 18*76, Vol. XL, p. 121) that this species dif- 

 fers from A. alpina of Europe and the Caucasus (with which it had been long conjoined) 

 in its more finely and narrowly dissected leaves, which have also the primary divisions 

 much more shortly petiolulate, and in the lengthened receptacle (sonaetimes an inch and 

 a half long) which in the other is small and hemispherical (even in fruit). Sir "William 

 Hooker describes Druiumond's specimens as from 6 in. to li ft. high, flowers white, with 

 a purplish tinge at the base, heads of pericarps very large, awns long, very silky.

Eastern declivity of the Rocky Mountains, lat. 52'' to 55°. — Dmmmond. Hitherto 

 unnoticed as a native of America. — Hooker, Fl. Bor.-Am. (1833). Top of Rocky Mountains 

 and W. Summit, near Kootanie Pass, 26th July, 1883. — Macoun. Mountains of Southern 

 British Columbia and Rocky Mountains, near the 49th parallel, at 6000 ft. altitude. — Dr. 

 G. M. Dawson. Kotzebue Sound.— Cfl/><. Beeclwj, (Torr. & Qr.) Rothrock. Mount Shasta 

 and Lassen's Peak, California. — Breirer ^- Watson. The indication in "Botany of Cali- 

 fornia " of the G-ulf of St. Lawrence (if our Atlantic St. Lawrence be meant) is no doubt 

 an error. Mr. Watson suggests (Bot. Calif) that the A. alpina of Arctic American collectors 

 is referable to this species, and I have therefore assumed that the Kotzebue Sound plant 

 belongs here. A. occidentalis had not been separated as a species in 1860, when Sir 

 Joseph Hooker (Distr. Arc. PL, p. 311) observed that he had seen but one Arctic American 

 specimen of A. alpina, which was much stunted, and that it had not been foiind east of 

 the Caucasus in the Old World, though it is not uncommon in North America on both 

 sides of the Rocky Mountains. 



5. — Anemone Baldensis, Linnams. 



Leaves nearly glabrous and somewhat fleshy, ternately divided into laciniate tripar- 

 tite segments, lobes linear obtuse; the involucral leaves like the others, and shortly 

 petiolate, multifid. Scape villous, 1-flowered. Sepals 8—10 (DC), 6—8 (Hook.), oblong- 

 suboval, obtuse, spreading, somewhat villous externally, tinged with blue. The Mount 

 Balda Anemone.
