F r e q u e n t on shady sanby banks under hedges, and in
groves, ripening its capsules in February and March.
Root perennial, branched, densely woolly. Stems scattered,
simple, erect, leafy, an inch or two high. Leaves
bright-green, lanceolate, acute, serrated, waved, thin and
pellucid, with a central rib : soon after gathering they
wither and curl up, losing their original beauty. Stalk
terminal, solitary, red, straight, about as long as the stem.
Capsule curved and drooping, cylindrical, brown, with a thick
red edge. Outer fringe of 32 narrow teeth; inner as in the
foregoing. Lid hemisphaerical, with a long taper beak.
Veil cylindrical, brown, single, its point rough as if with the
rudiments of bristles, evincing its generical affinity to the preceding.
Indeed we consider the beauty of the Hedwigian
principles no where more conspicuous than in affording certain
characters by which this moss and the last are ranged under
Polytrichum, though destitute of a really double veil. How
wise is the Linnean axiom, a Genus dabit characterem, non
character genus !”
