220 ONAGRACE.E. Epilobium. 



In the Sierra Nevada, from the head of Kern River (Rothrock) northward ; at Ebbett's Pass 

 and Mt. Shasta (Brewer) ; at Crater Pass in the Cascade Mountains (Newberry) ; through all the 

 colder portion of North America, and also in the European Alps and the Himalayas. 



++ -n- Leaves strictly sessile : not alpine. 



7. E. Franciscanum, Barbey. Somewhat hoary, roots spreading in the mud : 

 stem straight, branching above, with 2 to 4 elevated longitudinal lines, 12 to 20 

 inches high : leaves mostly opposite, connected at base, nearly glabrous, oblong- 

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

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

 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 (Bigcloui, Torrey) ; Lobos Creek (Kellogg) ; also at the Shumagin Islands, 

 Alaska, Harrington. 



8. E. brevistylum, Barbey. Somewhat hoary : stem terete, erect, 10 to 18 

 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 sessile : seeds acuminate at the top, 

 tufted with silvery hairs. Mon. Epilob. ined. 



Sierra County, Lemmon. Corresponding somewhat to the European E. roseum, 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. 

 iued. t. 5. 



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



In the Sierra Nevada : Yosemite Valley (Bolander) ; Sierra Valley (Lemmon) ; and collected 

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

 variable and perhaps embracing several species. 



+- -f- Annuals. 



10. E. paniculatum, Xutt. 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, FL i. 490 ; Barbey, Mon. Epil. ined. t. 8. 



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

 eastward to the Rocky 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. Fl. i. 207 ; Barbey, Mon. Epil. ined. t. 7. 

 Crossostiama Lindleyi, Spach, Mon. Onag. 84.
