 Racemes few-flowered, loose, the pedicels longer. D. menziesii. 



D. simplex Dougl. Roots short, thick: stems strict, erect, puberulent, 

 30-80 cm. tall, usually simple, rarely with a few erect branches: leaves 

 parted into many lobes, these linear in the upper leaves, broader in the 

 lower ones; only the lower petioles exceeding the blades: raceme spike-like, 

 the pedicels shorter than the pale-blue flowers: calyx pubescent outside, the 

 short sepals exceeded by the stout spur. Very variable: our form, common 

 in low meadows, is not typical. 



D. menziesii DC. Root consisting of fasciculate tubers, which are usu- 

 allv short and thick: stem erect, simple or branched above, 30-70 cm. tall, 

 glabrous or puberulent: leaves 3-7-parted, the divisions entire or deeply cleft 

 into 2-4, usually 3, lobes, the ultimate segments linear or lanceolate; petioles 

 mostlv exceeding the blades: racemes loose, 5-25-flowered; pedicels spread- 

 ing, mostlv as longas or longer than the dark blue flowers: sepals pubescent 

 on the outside, 2-2.5 cm - l° n g : spur as long, mostly acute and slender: 

 follicles 3, strongly diverging, pubescent or glabrous, 1.4-3 cm - l°ng- Com- 

 mon on rocky hillsides. 



116. ACONITUM. 



Tall erect ascending or long-trailing perennial herbs: leaves 

 palmately-lobed or divided: flowers large, showy, in terminal 

 racemes or panicles: sepals 5, petal-like, very irregular, the upper 

 one hooded or helmet-shaped: petals 2-5, the upper two hooded, 

 on long claws, concealed in the helmet: stamens numerous, pistils 

 3-5, many-ovuled, forming follicles at maturity. 



A. COlumbianum Nutt. Stems erect, .5-1 m. tall, somewhat pubescent 

 or viscid above: leaves glabrous or the tipper puberulent, palmately 5-lobed; 

 lobes cuneate-obovate, incisely serrate or cleft; petioles mostly shorter than 

 the blades: flowers blue, rarely white, in loose racemes or panicles: hood 2-3 

 cm. long, the helmet-shaped upper part higher than broad, strongly beaked: 

 follicles oblong-linear, 1-1. 5 cm. long, the slender beak usually recurved. 

 Along the North Fork of the Palouse and in the Thatuna Hills. 



117. ANEMONE. 



Erect perennial herbs: leaves compound or divided, all radical, 

 except 2 or 3cauline which form an involucre usually remote from 

 the flower: peduncles 1 -flowered, solitary or in umbels: sepals 

 4-20, petal-like: petals none: stamens numerous: pistils numerous; 

 akenes pointed or tailed, flattened not ribbed. 



A. quinquefolia L. Stems erect, i-flowered, 10-20 cm. tall, smooth or 

 pubescent: radical leaf and the three of the involucre similar, ternate or often 

 5-foliolate, petiolate, the leaflets or divisions oblong-cuneate or ovate, acute 

 or acuminate, incisely toothed or lobed, 3-5 cm. long: sepals 4-7, oval, white: 

 akenes puberulent, the style short. Moist woods, Thatuna Hills.
