48 RANUNCULACE^. Delphinium. 



++ ++ Stems lax (either low or tall), beariug a loosely flowered raceme of comparatively 

 large and not very numerous bright violet blue (rarely purple) flowers : pedicels spreading 

 or ascending, mostly decidedly longer than the fruit : follicles when well formed elon- 

 gated-cyliudraceous and two thirds to nearly a full inch long, often partly divergent at 

 maturity : herbage glabrous or nearly so. 



D. troUiifoliuna, Gray. Stems often reclining, 2 to 6 feet high, rather leafy : leaves 

 thiunish, orbicular or reniform in outline (larger ones 4 to 6 inches wide), 5-7-parted or 

 deeply cleft into cuueate divisions ; these 3-cleft and laciniate-lobed ; lobes acute, lanceolate 

 to almost linear : raceme iu larger plants a foot or two long and very loose : diverging 

 pedicels commonlv 2 inches long : sepals and spur usually three fourths inch long, upper 

 ones much surpassing the white upper petals: follicles (even ovaries) glabrous, mostly 

 recurving in age. — Proc. Am. Acad. viii. 375; Brew. & Wats. Bot. Calif, i. 11 ; Wats. Bibl. 

 Index, 14, excl. syn., & Bot. Calif, ii. 428.^ — Low or moist and partly wooded grounds, 

 Columbia River below the Dalles, first coll. by E. Hall, then Howell, &c. ; Humboldt Co., 

 California, Rattan ; there called Cow Poison. 



D. bicolor, Nutt. A span (when alpine) to a foot high, from fascicled and mostly deep- 

 descending roots, erect, rather stout : leaves thickish, seldom over an inch or two in diameter, 

 radical orbicular in outline, all deeply parted and divisions cleft or upper simply parted ; the 

 segments mostly linear and obtuse : raceme few-several-flowered : lower pedicels inch or two 

 long, ascending : sepals and spur half to three fourths inch long : upper petals pale yellow 

 or white and copiously blue-veined : follicles glabrous or when young puberulent, sometimes 

 quite erect, commonly recurving above. — Jour. Acad. Fhilad. vii. 10; Torr. & Gray, Fl. 

 i. 33 ; Gray, Bot. Gaz. xii. 52. D. Menziesii, Gray, Troc. Acad. Philad. 1863, 57, not DC.

 and E. Utah, north to Brit. America, west to E. Oregou and Washington; perhaps to 

 arctic Alaska. 



++++++ Stem strictly erect, a foot or two high, and bearing a virgate or narrow raceme : 

 pedicels ascending, even the lowest rarely over an inch long (except when converted into 

 leaf -bearing branch), and upper ones not longer than the spur : follicles oblong or oval, 

 not over about half inch long, not recurving in age : Californian species or nearly so. 

 = Fascicled roots elongated and not at all tuberiform. 



D. Andersonii, Gray. Robust, very glabrous, a foot or two high: leaves thickish, of 

 rounded outline (only an inch or two in diameter) and cuneate divisions ; the lobes short, 

 oblong or narrower, mainly obtuse : raceme commonly dense, a span or two long : sepals 

 oblong, deep blue, half inch long, a little surpassing the petals and shorter than the spur. —

 var. Nevadense, Brew. & Wats. Bot. Calif, i. 11, mainly. — Mountains of W. Nevada and 

 adjacent portion of the Sierra Nevada in California, Anderson, Watson, Stretch, Lemmon, &c. 

 Most resembles the last preceding species. 



D. Parryi, Gray, 1. c. Minutely puberulent or glabrous : stem 1 to 3 feet high from a rather 

 slender simple or very few-fascicled root, sparsely leaved : leaves thiunish, 3-5-parted ; the 

 divisions and few lobes linear or hardly Ijroader, mostly obtuse : raceme virgate, a span to a 

 foot long, at length rather loose : sepals oval or broadly oblong, deep blue, over half inch 

 long, much surpassing the petals, fully the length of the spur. — S. California, in San Ber- 

 nardino Co., Parrij (1850), Parry & Lemmon (1876), Parish. Apparently same near Santa 

 Barbara, Brewer, and San Clemente Island, Nevin & Lyon.^ 



D. Parishii, Gray, 1. c. Minutely puberulent, several-.stemmed from a simple or fasciculate 

 deep root, a foot or two high, rather rigid, sparingly leaved : leaves all with rather few 

 linear divisions and lobes, mostly small : sepals oblong, blue, only 3 or 4 lines long, hardly 

 surpassing the petals, shorter than the spur. — S. E. California, at Agua Caliente in the 

 Colorado Desert, Parish. (Adj Lower Calif, to All Saints Bay, Orcutt.)

 of them commonly fusiform-tliickened but not really tuberiform nor grumous : herbage
