NEW OR NOTEWORTHY SPECIES. 147 
second species of the genus. But this, as I learned by fur- 
ther study, was the real C. ranunculina; and during the 
succeeding years of residence in the region I did not again 
see the Colorado plant. Last spring I requested Mr. E. 
Bethel of Denver to go in search of it, giving him general 
directions as to its habitat, and with the result that I soon 
had fine flowering specimens of my long neglected plant, 
and later, some thoroughly mature achenes. "The species 
is very well characterized, by its few-flowered inflorescence, 
apetalous flowers, few stamens, and its short gibbous 
achenes in a hemispherical head. 
CLEMATIS BAKERI. Stems simple, erect, rather slender, 2 
feet high, leafy up to the short-peduncled nodding terminal 
solitary flower; herbage canescently short-villous or villous- 
lanate; leaves of lower and upper parts of the stem very 
diverse, the lowest pair oblanceolate, acute, entire, erect and 
either appressed to the stem or spreading, the next pair 
commonly pinnately divided in 5 or 7 remote lanceolate en- 
tire segments, the others successively much larger and parted 
into as many long-petiolulate and ternately compound, or 
finally decompound leaflets, their ultimate segments small 
and linear-lanceolate: peduncle seldom surpassing and 
often not even equalling the uppermost pair of decompound 
leaves: flower about ł to 1 inch long, dark-purple; sepals 
almost glabrous below the middle, white, tomentose toward 
the reflexed apex. ` 
On hillsides among scrub-oaks, at Los Pinos, southern 
Colorado, 19 May, 1899, the specimens in flower only. Re- 
lated to the well-known C. hírsutissima, Pursh, of far north- 
ern latitudes (commonly known as C. Douglasii) but a 
much taller plant, with smaller flowers, and very different 
foliage, this in C. Bakeri exhibiting extremes of diversity, 
as I have indieated. The perfectly distinct C. Scoitii of other 
sections of southern Colorado is in some sort intermediate, 
yet of different habit from either of these, and often several- 
flowered.
