 (Rhodora 20: 34. 1918.) (Epilobium adenocaulon Haussk.) Map 1483. 

 This variety was reported from Kosciusko County by Chipman (Proc. In- 

 diana Acad. Sci. 1896: 155. 1897) . He says that he found two specimens and 

 that these were sent to William Trelease, who had recently monographed 

 the genus, and that Trelease reported that they were this species. It was 

 also reported from Kosciusko County by Clark, and from Lake County by 

 Pepoon and by Peattie. I found this variety to be abundant in a springy 

 place at the base of the south bank of the southeast side of Lake Pleasant 

 about 4 miles northeast of Orland, Steuben County. Some of the mature 

 plants were up to 3 feet high.

Plants with stems. 



Flowers yellow; flower buds erect. 



Stamens of equal length ; seeds in two rows in each cell ; capsules subquadrangular, 

 the angles broadly rounded. 

 Capsules, when mature, 4-6 mm in diameter, tapering upward from a thickish 

 base; seeds with sharp angles and not strongly pitted. 

 Sepal-tips" terminal, hence connivent in the bud; seeds mostly 1.2-1.6 mm 

 long. 

 Stems not conspicuously angled, mostly reddish, somewhat strigulose and also 

 hirsute, or almost glabrous; leaves green; hypanthium, sepals, capsules, 

 and branches of inflorescence more or less hirsute and strigulose to 

 glabrous, but with quite evident gland-tipped hairs among the others.

 naming my specimens.
