Fr. June.—The stems, in all the states of this plant, (and they are very
numerous, though I have considered only two worthy of particular
notice), are simple or only branched very low down, and among the
roots. Far. a. is found from a span to a foot in height, with the
leaves very patent, often recurved, long and narrow, their margins
scarcely diaphanous. In /3. the stems do not often exceed 3-4 inches;
the /eaves are rather less patent than in a., and of a shorter and broader
figure, with their margins whitish and diaphanous. In both the leaves
are equally decidedly serrated.
7. P. alpinum, Linn, {alpine Hair- Moss); stems elongated
branched in a fasciculated manner, leaves patent subulato-lanceolate

glaucous (reddish only through age.)

usually short, leaves linear-lanceolate obtuse their margins plane
