Filaments slender, long-exserted, bearded at the middle ; anthers 

 linear or oblong, inflexed in the bud. Style slender, long-ex- 

 serted. Seeds 1-4, ovules only four. 



H. capitatum Dougl. Benth in Linn. Trans, xvii, 273. Retrorsely his- 

 pid with minute white hairs : stems often tufted, 4-12 inches high from 

 a small fascicle of thickened perennial perpendicular roots : one-several- 

 leaved, erect in flower, recurving and often prostrate in fruit: leaves long- 

 petioled, exceeding the stems, pinnately 5-7-parted or at base divided ; 

 ihe lanceolate divisions entire or often 2-3-lobed or 2-3 cleft, all mucron- 

 ate-tipped : flowers in a dense capitate cluster : calyx very hispid, parted 

 nearly to the base, with linear-oblong, obtuse divisions : corolla blue, but 

 little longer than the calyx : filaments twice as long as the corolla ; anthers 

 oblong, attached near the middle ; style equalling the stamens, 2-lobed : 

 seed a line in diameter. Under shrubs &c. Brit. Columbia to California 

 east of the Cascade Mountains. 



H. occidentale Gray Proc. Am. Acad, x, 314. Pubescent, hirsute, 

 or sparingly hispid : stems erect, usually numerous from a fascicle of 

 fleshy-fibrous roots, 12-18 inches high : leaves elongated-oblong in general 

 outline, pinnately parted or divided into 7-15 oblong, mostly incised or 

 cleft obtuse divisions 1-2 inches long: peduncles rather slender, elongated, 

 often surpassing the subtending leaf : cymes mostly dense or capitate : 

 calyx deeply parted, its divisions lanceolate and rather obtuse : corolla 

 white to violet-purple, 4-5 lines long: anthers oblong-linear. In moist 

 shady places, Washington to California. 



Var. Fendleri Gray I. c. Pubescence mainly hirsute or hispid, not 

 at all canescent or cinereous : divisions of the leaves broader, acute or acu- 

 minate, incisely serrate : peduncles shorter : cyme rather open : corolla 

 white or nearly so. In shaded ravines. Mount Adams, Washington, to 

 Colorado and New Mexico. 



H. Virginicum L. Sp. 146. Pubescent with short scattered hairs: 

 stems few or solitary from a short scaly rootstock, 1-2 feet high : leaves 

 very long-petioled, ovate or cordate in outline, 3-5-parted or divided, the 

 lobes or divisions 2-4 inches long, ovate-lanceolate to rhombic-ovate, acute 

 or acuminate, coarsely incised-toothed, the lowest commonly 2-cleft, and 

 the terminal one often 3-lobed : peduncle elongated, at length surpassing 

 the leaves, usually once or twice forked ; cymes at length open : calyx part- 

 ed to the very base into linear and spreading hispid-ciliate acute divisions : 

 corolla nearly white, or sometimes deep violet. 3-4 lines long: filaments 

 more than twice as long as the corolla ; anthers oblong, attached below the 

 middle. In rich damp woods, Oregon to Alaska and across the Continent. 



2 NEMOPHILA Nutt. Journ. Acad. Philad. ii, 179. 



Annuals with mostly opposite and usually pinnatifid leaves, 

 and usually large flowers on rather long axillary peduncles. 

 Calyx deeply 5-cleft or 5-parted, with a reflexed or spreading ap- 

 pendage in each sinus, enlarged in fruit. Corolla rotate or nearly 

 campanulate, usually longer than the calyx: the base within 

 mostly with 10 appendages. Stamens shorter than the corolla: 

 anthers usually sagittate-oblong. Ovules 4-20. Seeds commonly 

 with a deciduous or more persistent caruncle. 



N. Menziesii H. & A. Bot. Beech. 125. Sparingly strigose-pubescent : 

 diffusely branched from the base, the branches mostly prostrate, 2-10 

 inches long: leaves oblong in outline on rather short winged petioles, 3-9 

 parted into rounded obovate lobes 1-3 lines long: peduncles 2-3 inches
