Delphinium. KANUNCULACE^E. \\ 



In the Coast Ranges from Santa Barbara (Brewer) to Punta de los Reyes, Biydow. A frequent 

 and showy species, varying in its colors. Distinguished from D. decorum, to which it has usually 

 been referred, by its hairy ovaries, leaves all dissected, and greater pubescence. 



D. MENZIESII, DC., is a similar species, glabrous below, at least at the very base, pubescent 

 above with spreading hairs, especially the inflorescence : flowers large, deep blue ; the upper 

 petals veined with purple ; the spur long and slender. From Puget Sound to Montana and the 

 Blue Mountains of Oregon, apparently not entering California. Reported also from Kotzebue 

 Sound. The D. Mciizicsii of the Colorado Flora is D. BICOLOR, Nutt. (D. Menziesii, var. Utah- 

 ense, Watson, Bot. King Exp. 12), very similar and perhaps only a variety, but it has uniformly 

 smaller flowers and is glabrous throughout (including the ovaries), or occasionally somewhat 

 tomentose-pubescent. 



3. D. decorum, Fisch. & Mey. More or less pubescent with spreading hairs, 

 but usually nearly glabrous : stem 6 to 15 inches high : lower leaves 5-lobed, spar- 

 ingly toothed, the upper with narrow linear divisions : flowers large, deep blue, 

 long-pedicelled in an open raceme ; sepals broad, 6 to 9 lines long, spreading ; spur 

 usually long and narrow : ovary and capsule glabrous. Torr. & Gray, Fl. i. 661. 

 J). patens, Eenth. PL Hartw. 296. 



Var. Nevadense, Watson. Scarcely differing but in the smaller flowers and 

 leaves often all linear-lobed. D. Menziesii, Watson, 1. c., excl. var. 



In the Coast Ranges from Santa Barbara (Brewer, and perhaps from San Diego, Parry) to Men- 

 docino Co. The variety is found in the central Sierra N evada, and is frequent on the mountains 

 and foot-hills of W. Nevada. Often glabrous excepting the ciliate bracts and somewhat villous 

 flowers. 



4. D. depauperatum, Nutt. Perhaps only a form of the last variety, with 

 the ovaries pubescent. Most of the specimens, however, are very slender and few- 

 flowered, the lower leaves reniform in outline, 3 5-parted, the rather broad lobes 

 entire or few-cleft. The pubescence of the inflorescence is usually straight and 

 spreading. Torr. & Gray, Fl. i. 33. Watson, Bot. King Exp. 12. 



In the Sierra Nevada from the head of the Kern (Rothrock) to the Blue Mountains, Oregon, and 

 eastward in the mountains of Nevada ( Watson). 



-t- + Stout and tall : root perennial but not tuberous. 



5. D. Californicum, Torr. & Gray. Stems nearly or quite smooth below : 

 leaves large, 3 to 5 cleft, the divisions variously lobed : raceme strict, close-flowered 

 above : pedicels and flowers densely velvety pubescent. Torr. & Gray, Fl. i. 31. 

 D. exaltatum, Hook. & Arn. Bot. Beechey, 317. 



Dry soils near the coast. Stems stout, 2 or more feet high. Lower leaves 3 to 5 inches in 

 diameter, usually deeply 5-cleft, the divisions cuneate at base and laciniately toothed or lobed. 

 Flowers commonly a light but dull blue, often more or less tinged with violet. 



6. D. SCOpulorum, Gray. Stems tall, smooth or puberulent : lower leaves on 

 long petioles which are dilated at the base, 3 - 5-parted, the divisions laciniately 

 lobed, the lobes sharp-pointed : raceme rather strict : flowers sparingly pilose with- 

 out. PL Wright, ii. 9. 



Big Tree Road (Brewer) ; Sierra Valley (Lemmon) ; a stout form, 5 to 6 feet high, differing 

 from that prevalent in the mountains of Colorado in the less narrowly divided leaves and nearly 

 glabrous inflorescence. It is still less like D. elatum, var. (?) occidentale, of the mountains east- 

 ward, which with very similar habit and foliage has the raceme densely pubescent with straight 

 spreading subviscid hairs, stout pedicels, and usually larger flowers with longer curved spurs. 

 The pubescence in D. scopulorum is shorter, more woolly and appressed, and the pedicels are 

 slender. 



7. D. trolliifolium, Gray. Glabrous throughout or slightly villous : leaves 

 large, long-petioled, 5 - 7-lobed, the lobes laciniately cleft and toothed with acumi- 

 nate segments : raceme loosely few-flowered, with long pedicels : flowers bright 

 blue, 1 1 inches broad, the spur as long as the sepals : capsules glabrous. Proc. 

 Am. Acad. viii. 275. 



Oregon, Hall. Specimens collected by Kellogg in Mendocino Co. seem referable to this
