2. Epilobium alpinum, Linn. Alpine Willow-lierb. 

 Stem creeping at the base, usually marked witli 2 pubescent lines ; leaves opposite, ovate 



or ovate-oblong, slightly petioled, denticulate, smooth ; stigma entire ; capsules mostly pe-

Perennial. Stem 1-3 feet high, late in the season very much branched, a little pubescent 

 or nearly smooth, mostly of a purj^iish color ; the branches marked by four narrow lines, two 

 of them slightly elevated and decurrent from the midrib of the leaves ; the others intermfediate, 

 pubescent. Leaves 3-6 inches long, acute, smooihtsh, marked with, very minute roundish 

 and narrow dots. Flowers numerous, terminating the branchlels, 2-3 lines in diameter. 

 Sepals lanceolate, ratlier shorter than the corolla. Petals pale purple, or sometimes nearly 

 white. Stamens unequal. Slyle scarcely included. Capsule about % inches long when mature.

 larger flowers, and more deeply cleft petals.
