190 RANUNCULACEAE 



narrow, deeply cleft and recleft into narrowly linear lobes, puberulent ; raceme densely flowered 

 and 6-15 cm. long, or often more elongated and the flowers more distant; pedicels ascending, 

 3 cm. long or less, or in the elongated open racemes often longer; sepals deep violet-purple, 

 elliptic, 10-15 mm. long, rather thinly puberulent on the back, the spur straight, a little exceeding 

 the sepals ; upper petals white, tinged with purple, notched or entire, lower petals violet, often 

 crenate; follicles straight to the divergent tips, 1CM2 mm. long, puberulent; seeds with a loose 

 cellular coat forming wings on the angles. 



Dry hillsides and mesas, Upper Sonoran Zone; Monterey County, California, to Lower California. Type 

 locality: San Bernardino County, California. April-June. 



25. Delphinium variegatum Torr. & Gray. Royal Larkspur. Fig. 1802. 



Delphinium variegatum Torr. & Gray, Fl. N. Amer. 1 : 32. 1838. 



Stems from short fascicled often fusiform roots, erect, simple or branched, 2-5 dm. high, 

 usually hirsute-pubescent below, short-pubescent above. Leaves 2.5-4 cm. broad, 5-lobed, the 

 divisions cleft and lobed into oblong-obtuse to linear-acute lobes ; raceme simple or with one or 

 two branches, usually less than 10 cm. long, pedicels ascending or somewhat spreading, short 

 hirsute-pubescent; sepals broadly oval, 15-20 mm. long, deep violet-purple, rarely varying to 

 pink, sparsely short-pubescent, the spur stout, scarcely equaling the sepals; upper petals white 

 or yellowish, often tipped with purple, lower petals violet or rarely white; follicles erect, 12 mm. 

 long ; seeds very narrowly winged. 



Grassy hillsides, usually in rocky soil, Upper Sonoran Zone, upper Sacramento Valley and Lake County, 

 south to San Luis Obispo County, California. April-June. 



Delphinium variegatum var. apiculatum Greene, Fl. Fran. 304. 1892. (D. apiculatum Greene, Pittonia 

 1: 285. 1889.) Flowers smaller, the sepals 10-15 mm. long, more numerous in a more elongated narrower 

 raceme. This replaces the typical species throughout most of the foothill region surrounding the San Joaquin 

 and the lower Sacramento Valleys, California. 



10. ACONITUM [Tourn.] L. Sp. PL 532. 1753. 



Erect, ascending or sometimes trailing herbs, with usually elongated stems, palmately 

 lobed leaves, and large irregular flowers in racemes or panicles. Sepals 5, petaloid, the 

 upper one hooded or helmet-shaped. Petals 2-5, the two upper hooded, long-clawed, con- 

 cealed in the hooded sepal, the three lower, when present, minute. Stamens numerous. 

 Pistils 3-5, sessile, many-ovuled, forming follicles in fruit. [The ancient Greek name.] 



A genus of about 60 species, inhabiting the subarctic and cool temperate regions of North America and 

 Eurasia. Type species, Aconitum lycoctonum L. The roots, and in some species the flowers also, poisonous. 



1. Aconitum columbianum Nutt. Columbia Monkshood. Fig. 1803. 



Aconitum columbianum Nutt. in Torr. & Gray, Fl. N. Amer. 1: 34. 1838. 



Plants usually tall and rather stout, 5-20 dm. high, glabrous below, pubescent_ or tomentose 

 above and often a little viscid. Leaves 5-15 cm. broad, deeply 3-5-cleft, the divisions cuneate 

 below, laciniately toothed and cleft; flowers in rather loosely flowered simple or few-branched 

 racemes; hood 10-15 mm. long, the helmet portion higher than broad and in age much shorter 

 than the narrowed lower portion, strongly beaked; follicles 10-15 mm. long. 



Moist soil, Canadian Zone; British Columbia to the southern Sierra Nevada, California, east to Montana 

 and New Mexico. In Washington and Oregon it is chiefly east of the Cascade Mountains. Type locality: 

 "Springy places on the Oregon below Walla Walla." July-Aug. A variable species and a number of segregates 

 have been proposed. (Greene in Rep. Nov. Spec. 7: 1-6. 1909.) 



Aconitum bulbiferum Howell, Fl. N.W. Amer. 25. 1897. This species is based upon slender weak- 

 stemmed plants with smaller leaves, and with most or in some cases all the flowers reduced to stalked or 

 axillary bulblets. Plants of this type are not infrequent in the Cascade Mountains and in the Sierra Nevada, 

 but according to the author's field observations they seem to be a mere state or form of cohnnbianum, as all 

 gradations can be found between them and the ordinary flowering form in the same communities. 



Aconitum columbianum subsp. pallidum Piper in Piper and Beattie, Fl. S.E. Wash. 110. 1914. {Aconi- 

 tum gracilentum Greene, Rep. Nov. Spec. 7: 1. 1909.) Flowers white or cream-colored with the edges sometimes 

 tinged with purple. The common form in the higher altitudes of the Blue Mountains of Washington and Oregon. 



11. ANEMONE L. Sp. PI. 538. 1753. 



Erect perennial herbs. Leaves compound or divided, all basal, except 2 or 3 forming 

 an involucre subtending or remote from the flower. Peduncles 1-flowered, solitary or 

 umbellate. Sepals 4-20, petaloid, and usually showy. Petals none. Stamens and pistils 

 numerous. Fruit a head of numerous flattened ribless achenes, their styles short, glabrous 

 or pubescent. [Name from the Greek, meaning a flower shaken by the wind.] 



A genus of about 85 species widely distributed in the subarctic and temperate regions of both hemispheres. 

 Type species, Anemone coronaria L. 



Achenes densely woolly. 



Stems from the simple or branching crown or a woody taproot. 



Leaves simply ternate, the segments broadly cuneate or flabelliform. 1. A. parvi flora. 

 Leaves 2-4-ternate, the segments linear to narrowly oblanceolate. 



Styles rather stout, 1-3 mm. long. 2. A. globosa. 



Styles very slender, 4-6 mm. long. 3. A. Drummondii. 



Stems from a fusiform tuber. 4. A. tuberosa. 

 Achenes not woolly; stems from horizontal rootstocks. 



Involucral leaves simple. 5. A. dcltoidea. 



Involucral leaves 3-5-foliolate. 6. A. quinquej 'olia Grayi.
