Larkspur. Knight’s-spur. 
Lark-heel. (Fig. 1562.) 
Delphinium Consolida \,. Sp. Pl. 530. 1753. 
Erect, glabrous, or somewhat pubescent, 1-214° 
high, divaricately branched. Leaves short-peti- 
oled or sessile, all divided into narrowly linear cleft 
or toothed segments; racemes terminal, rather 
loose, 6’—10’ long; flowers on short pedicels, blue 
or white, 1/-114’ long; spur slender, bent near the 
middle; petals 2, united; carpel 1, forming an 
erect glabrous follicle in fruit, tipped with a short 
slender beak. 
In waste places, naturalized from Europe in south- 
ern New Jersey, Pennsylvania and southward, locally 
adventive or fugitive northward. Summer. Delphin- 
tum Ajsacis of the gardens, which is commonly culti- 
vated and occasionally seen outside of fences, may be 
distinguished from this species by its pubescent fol- 
licles, shorter spurs, longer and denser racemes.
