de Candolle

Syst. Nat. 1: 355. 1817.

Common names: Menzies' larkspur
IllustratedEndemic
Treatment appears in FNA Volume 3.

Stems (10-) 35-70 (-85) cm; base often reddish, puberulent. Leaves basal and cauline; basal leaves 0-4 at anthesis; cauline leaves 3-7 (-10) at anthesis; petiole 0.5-11 cm. Leaf-blade round, 1.5-5 × 3-9 cm, puberulent; ultimate lobes 5-18, width 2-15 mm (basal), 1-10 mm (cauline), widest at middle or in proximal 1/2. Inflorescences 3-15 (-43) -flowered; pedicel 1.5-4 (-7) cm, (glandular) puberulent; bracteoles 8-10 (-24) mm from flowers, green to blue, linear, 4-6 (-9) mm, puberulent. Flowers: sepals bluish purple or yellowish, often partly fading upon drying, puberulent, lateral sepals spreading, (11-) 13-20 × 5-11 mm, spurs straight, ascending less than 30° above horizontal, 11-17 mm; lower petal blades ± covering stamens, 8-12 mm, clefts 0.2-2.5 mm; hairs sparse, centered, mostly near junction of blade and claw above base of cleft, white or blue. Fruits 11-17 mm, 3.5-4 times longer than wide, puberulent. Seeds wing-margined; seed-coat cell surfaces smooth, without swollen blunt hair.

Discussion

Subspecies 2 (2 in the flora).

Although Delphinium menziesii has often been confused with D. nuttallii, it may be distinguished by its consistently larger flowers and usually fewer flowers per plant. Interestingly, each species produces both blue-purple and yellowish flower colors in separate populations.

The Chehalis consider Delphinium menziesii poisonous, but they also apply it to sores. The women of the Thompson Indians use it as a love charm (D. E. Moerman 1986, subspecies not indicated).
