KEY TO SPECIES. 
Flowers usually 10 to 20; leaves rather few; puberulence, at 
least of the inflorescence, villous in character and 
somewhat viscid _-.-_-_..--_------eee 1. D. eyanoreios, 
Flowers more numerous; leaves rather many ; puberulence not ‘ 
villous, more or less appressed. 
Leaves puberulent, usually densely so, all with narrow 
divisions; puberulence of inflorescence usually viscid___ 2. D. simples. 
Leaves glabrous or mostly so, the lower with broad divi- 
sions; puberulence of inflorescence usually not viscid__ 3. D. distichum. 
1. Delphinium cyanoreios sp. nov. 
Stems strict, erect, usually simple, 40 to 99 em. high from a thick tuberiform 
root, at least the inflorescence densely velutinous and somewhat viscid, the 
jower portion of the plant puberulent or glabrate; leaves few, the basal usually 
glabrous, parted into 3 cuneate divisions, these again cleft into linear, obtuse 
lobes; upper leaves reduced and more deeply cleft into narrower segments; 
raceme 10 to 30-flowered, 10 to 30 em. long, the pedicels decidedly shorter than 
the spurs; bracts linear-lanceolate: calyx dark blue, sparsely villous without. 
the straight spur 12 to 14 mm. long, much longer than the sepals; upper petals 
whitish, veined, tinged with blue at the tips; carpels 8, 12 to 20 mm. long with- 
out the beak, villous, straight or slightly spreading at maturity; seeds dark, 
smooth, the angles produced into narrow white margins. 
This is the plant Dr. Gray described as D. simplex Dougl.,’ but it is not 
the plant of Douglas. It oceurs mainly in the Blue Mountains of Oregon. 
Type in the U. 8. National Herbarium, no. 529341, collected near Sled Creek 
Ranger Station, Wallowa County, Oregon, June 25, 1907, by Frederick V. Coville 
(no. 2444). 
Among the specimens in the U, S. National Herbarium are, in addition, the 
following: 
OREGON: Blue Mountains, Sheldon 8399: Billy Meadows, Blue Mountains, 
1,500 meters alt., J. T. Jardine 812: head of Anthony Creek, Blue Moun- 
tains, 2,100 meters alt., Cusick 2389; Silver Creek, Harney County, 
Cusick 2609; eastern Oregon, Cusick 2181. 2204; Steens Mountain, 
Cusick 1982; Two Color Creek, Blue Mountains, Cusick 3305a; Cliff 
Creek, Blue Mountains, Cusick 33825; source of Rock Creek, Blue 
Mountains, Cusick 3175. 
IDAHO: Craig Mountains, June 23, 1894, Henderson ; South Clearwater, June 
26, 1894, Henderson; near Sawtooth, Everman 603; Long Valley, Hen- 
derson 3140. 
Delphinium depauperatum Nutt. is distinguished from the present species 
almost wholly by the more elongated lower pedicels, but some specimens like 
Cusick’s nos. 3325 and 3175 are ambiguous in this respect. The pubescence of 
the two species is identical. 
2. Delphinium simplex Dougl.; Hook. Fl. Bor. Amer. 1: 25. 1829. 
In its original locality this species grows in stream bottoms and moist 
meadows and has uniformly pale, dull blue flowers. Douglas’s types represent 
this form. Elsewhere in eastern Washington the flowers are a deeper, brighter 
blue, but the other characters remain the same. This brighter flowered plant 
matches the type of Delphinium strictum A. Nels., but it is scarcely worthy of 
nomenclatorial recognition.
