 the shape of the Ho war.) — Aii'iual or pereiiuial herbs (of northern temperate 

 regions) ; with palmately cleft oi divided leaves, and racemose or pauiculatr- 

 liowers, commonly showy. — Inst. 42G, t. 241 ; L, Gen. no. 44'J ; Gray, Gen. 111.

§ 1. CoNSOLiDA, DC. Carpel and foUicle only one : petals (in ours only 2) 

 united into one body : Old World annuals, or rarely more enduring, low ; with 

 leaves dissected into narrow linear or filiform divisions : flowers blue or violet, 

 varying to purple and white. — Syst. i. 341. 



D. Coss6lii)A, L. Loosely paniculate in inflorescence : slender spur horizontal : follicle gla- 

 brous : seeds with interrupted transverse ridges. — Spec. i. 530; Reicheub. Ic. V\. Germ. iv. 

 t. 66. —Old grain-fields, &c.,rare, Virginia, &c. (Nat. from Eu.) 

 D. A.jAcis, L. Flowers more numerous and si)icatcly racemose: follicle jjubo.sceut; seeds 

 with rugosely broken ridges. — Spec. i. 531 ; Keichcub. 1. c. t. 67. — Escaped from gardens 

 in Canada and Atlantic and i\Iiddle States, in certain places. D. on'entali-, Gay, a common 

 garden Larkspur with more shovy (violet-colored) flowers in a denser raceme, is thought to 

 be the original D. Ajacis, L. ; according to Lawsou, Rev. Canad. Rauunc. 80, it has been 

 collected in the far interior of Canada, probably from a cultivated plant (Nat. from Kii.) 



§ 2. Dkhmiinastkum, DC. 1. c. 351. Carpels 3 to 5 : flowers never scarlet or 

 orange : petals 4, distinct ; upper pair usually glabrous, extending backward into 

 spurs ; lateral ones unguiculate, more or less hairy on the face, in ours emarginate 

 or 2-lobed at apex: follicles in ours almost always 3: perennials. In several 

 species, such as D.tricorne, the caulicle does not lengthen in germination, but the 

 connate petioles of the cotyledons do so, and the plumule comes out from the 

 base of the false stemlet which is thus formed. 



* Seeds with a clo-^e smooth coat, dark-colored : stoni few-leaved, from a fascicu'i.ite-tubcr- 

 ous root : Atlantic species. 



D.tricorne, Micux. Low, succulent : leaves deeply .and somewhat pedately ."vpartcd and 

 divisions cleft and laciuiate into a few narrow hjbes . raceme loose, few-many -flowered : 

 flowers bright blue, or variegated with white (not rarely white) : spur .isceuding, half or 

 three fourths inch long : follicles 3, half inch to inch long, strongly diverging at maturitv. —
