1906] ' NELSON—ROCKY MOUNTAIN PLANTS 51 
Delphinium Cockerelli, n. sp.—Tawny-pubescent on stems and 
in the inflorescence, densely and viscidly so above; the leaves obscurely 
pubescent: stems nearly simple or bushy-branched, 6-12 high: 
leaves large, often 12-18°™ in diameter, the veins strikingly super- 
ficial, about 5-cleft or parted into broadly oblong or oblong-cuneate 
divisions, these merely coarsely toothed or incised above the middle: 
racemes often several, open, with rather long peduncles and pedicels 
and few flowers (5-10) : flowers bright-purple, large (3-4°™ long) : sepals 
oblong-lanceolate, acute, about as long as the thick curved spur: 
petals small; the upper yellowish-white, concealed within the upper 
sepal; the lower purple, with suborbicular blade, cleft and sparsely 
hirsute ciliate. 
An unusually handsome species, with somewhat the aspect of A. subalpinum 
(Gray) A. Nels. Bull. Torr. Bot. Club 27:263. The type was collected by 
Mrs. O. St. John, no. go, Baldy Mts., Elizabethtown, N. M., Oct., 1898. It 
was communicated to me by Professor Cockerell, who called my attention to 
some of its distinguishing characters. C.F. Baker’s no. 325, near Pagosa Peak, 
Colo., is also quite typical. 
Aconitum lutescens, n. sp.—Root’ small, fusiform-tuberous: 
stems slender, simple, erect, only 3-6 high, glabrous nearly to the 
inflorescence: leaves 3-5°™ broad; the 5 broadly cuneate divisions 
deeply and incisely toothed above the middle: raceme narrow, long 
for the plant, rather open; the flowers a pure cream-color, becoming 
nearly white or pinkish in drying; rachis and pedicels softly 
hirsute-ciliate with straight viscid hairs standing out at right angles. 
This Aconitum with its fine cream-colored flowers may best stand as a species. 
Collections of it are as follows: Aven N elson, no. 1521 (type), Cummins, Wyo., 
July 1895; T. D. A. Cockerell, no. 87, Beulah, N. M., 1898; W. S. Cooper, no. 
274, Estes Park, Colo., July 1904. 
Anemone zephyra, n. sp.—Green but sparsely long-pilose: stems 
one or more from the thick erect caudex, 7-15°™ high, rather stout: 
basal leaves petioled, ternate, the broad petiolulate segments in 
turn deeply incised into linear-oblong lobes; involucral leaves sessile, 
with linear-oblong lobes: flowers large, 2-3°™ broad, lemon-yellow 
or ochroleucous, usually solitary and rather long-pedunculate, some- 
times umbellately 2-4-flowered: achenes large, glabrous, obovate, 
tapering to a stipe-like base, tipped with the short hooked style.
