 nate above, mostly about equally spaced, ovate to linear, mostly 1-5 cm. long, 

 entire to serrulate; flowers few, nodding to erect; pedicels 5-50 mm. long; hypan- 

 thium 1-2 mm. long; sepals 1.5-6 mm. long; petals white to deep-pink or lilac-rose, 

 notched. 3-13 mm. long; stigma entire; capsule 2-7 cm. long, linear to subclavate; 

 seeds about 1 mm. long, smooth to obscurely papillate, the coma dingy or some- 

 times white. E. oregonense Hausskn., E. Hornemannii Reichenb. 



Wet meadows, bogs, seepage slopes and wettish open woods, in N. M. (Grant. 

 San Miguel and Socorro cos.) and Ariz. (Apache and Coconino cos.), June-Sept.; 

 throughout mts. of w. N.A., s. to Calif., Ariz, and N.M., e. to Atl. coast; Euras. 



4. Epilobium coloratuni Biehler. 



Perennial herb with sessile basal rosettes, 5-10 dm. tall, usually well-branched 

 above, minutely strigulose above (especially along elevated lines decurrent from 

 the margins of the petioles); hypanthium about 0.5 mm. long; sepals 1.5-3 mm. 

 long; petals pink, 3-5 mm. long; capsule 3-4.5 cm. long; seeds about 1.5 mm. 

 long, the coma cinnamon-colored. 



Rare in wet places, in Okla. (Waterfall) and Tex. High Plains (Hemphill and 

 Wheeler cos.). July-Oct.; Que. to S.D., s. to Ga., Okla. and Tex.; Hisp. 



5. Epilobium Watsonii Barbey. Fig. 564. 



Perennial but often blooming the first season, eventually spreading by short root- 

 stocks that produce rosettes of leaves but no turions; stems 3-10 dm. tall, usually 

 simple below but branched above, often glandular above (especially in the inflor- 

 escence), weakly to densely pubescent with the hairs either in decurrent lines or 

 more general; leaves opposite, short-petiolate to subsessile. narrowly lanceolate to 

 ovate-lanceolate, 3-7 cm. long, more or less serrulate; inflorescence mostly com- 

 pound; sepals 2-5 mm. long, often purplish; petals 3-10 mm. long, notched, white 

 or cream-color to deep purplish-red; stigma entire or if lobed the lobes mostly 

 coalescent; capsule linear, 4-8 cm. long, strigillose to glandular-puberulent; seeds 

 0.5-1.2 mm. long, distinctly crested-papillate in numerous parallel longitudinal 

 lines; coma white. £. adenocaulon Hausskn. and its var. perplexans Trel., E. cali- 

 fornicnm Hausskn., (?) E. ciliatiim Raf. 



In wet meadows, marshes, seepage areas, in water of springs, ditches and ponds 

 and on edge of streams in mud or boggy areas, in N.M. (widespread) and Ariz. 

 (Navajo and Coconino cos.), July-Oct.; rather generally spread over much of the 

 U.S., Can. and Alas.
