 lanceolate, rounded at base, serrulate : bud ovoid : top of the ovary much contracted 

 at the insertion of the calyx : sepals slightly hoary : petals purple, eniarginate : 

 stamens shorter than the style : stigma cylindrical : capsule hoary : seeds with 

 striate testa and broad sides to the furrows. — Mon. Epil. ined. 



Near San Francisco (Bigelow, Torrey) ; Lobos Creek (Kellogg) ; also at the Shumagin Islands, 

 Alaska, Harrington.

 inches high, slightly branched at top, marked with 2 or 4 decurrent glabrous lines, 

 tinted with purple : leaves mostly opposite, sessile, broadly lanceolate, slightly den- 

 ticulate with rigid teeth : flowers small : calyx cleft nearly to the middle, almost 

 glabrous: petals slightly cleft, obcordate, pinkish : inner row of stamens short; the 

 outer ones longer than the style: capsule nearly sessde: seeds acuminate at the top, 

 tufted with sdvery hairs. — Mon. Epilob. ined. 



Sierra County, Zemmon. Corresponding somewhat to the European E. roscum, Schreber. 



9. E. glaberrimum, Barbey. Whole plant glaucous and perfectly glabrous, 

 stoloniferous : stem terete, straight, simple or somewhat curved and branching, 

 6 to 15 inches high: leaves mostly opposite and connected at the base, broadest 

 below, bluntly lanceolate, slightly serrulate : sepals somewhat shorter than the 

 petals, which are deeply notched : filaments rather short and thick : stigma club- 

 shaped, with a slight depression at top : capsule very slightly hoary : seeds with 

 furrows terminating below the apex, tufted with very fine hairs. — Mon. Epilob. 

 ined. t. 5. 



Var. latifolium, Barbey, 1. c. Leaves broader : stem more branching, curved. 



In the Sierra Nevada : Yosemite Valley (Bolander) ; Sierra Valley (Lem.rn.on) ■ and collected 

 also by Bridges. The variety in Sierra Co. (Lcmmon), and above Carson City, Anderson. Rather 

 variable and perhaps embracing several species. 



+- +- Annuals. 



10. E. paniculatum, Nutt. Glabrous or pubescent above (rarely throughout): 

 roots spreading : stem erect, slender, 10 inches to 10 feet high, terete, dichotomous 

 above : leaves narrowly linear, obscurely serrulate, acute, attenuate at the base, 

 mostly alternate and fascicled ; the uppermost subulate : flowers few, terminating 

 the spreading filiform and almost leafless branches : pedicels pubescent : calyx-tube 

 funnelform : petals obcordate, nearly twice the length of the calyx-lobes : capsule 

 short, acute at each end, straight or a little curved, erect or speading. — Torr. & 

 Gray, El. i. 490 ; Barbey, Mon. EpU. ined. t. 8. 



From the Cuiamaca Mountains and the Southern Sierra Nevada to Washington Territory, and 

 eastward to the Eocky Mountains ; frequent. 



11. E. minutum, Lindl. Roots bright and shining: stem terete, erect, puber- 

 ulent, occasionally branching, 3 to 10 inches high : leaves mostly alternate, elliptic- 

 lanceolate, rather obtuse, nearly entire, slightly pubescent : flowers minute, con- 

 tracted at the base of the calyx : petals pale rose-color, obcordate : the four longer 

 stamens equalling the style : stigma clavate, the lobes at length expanded and fim- 

 briate : capsule short, somewhat pedicelled, slightly arcuate, at length erect : seeds 

 large and not very numerous. — Hook. El. i. 207 ; Barbey, Mon. Epil. ined. t. 7.
