H ab. Ba rren spongy f s n e a r th e summits o f th e Scotch and Irish mounta ins, abundant.
P la n t grow in g always in very th ickly-m a tted tu fts , often core rin g a surface of ground o f some
fe e t in d iam e te r; conspicuous a t a considerable distance from its silvery hue.
Stems nearly e rect, occasionally procumbent a t th e base, va rying from th e ir most common
he ig h t of scarcely h a lf a n in ch to a n inch o r more , simple, o r b e a rin g he re and the re
a few, sc a tte red, p a te n t o r suberect bi-anches, which, as well as th e stems themselves,
are cylindrical and filiform in th e ir lower pa rts, b u t towards th e apices visibly incras-
sated an d compressed: tlie color o f bo th stems and branches is a d irty brow n ; when
dry they a re brittle .
Leaves (f. f. 4 . 5) e rect, bifarious, closely imbric a ted in two rows, so as entirely to conceal
th e stem , resembling (as I Jg h tfo o t well rem a rk s), un d e r a highly-magnifying power,
th e te x tu re o f a braided lock o f h a ir, or th a t o f a pla ited-thonged w h ip : they are
concave, ovate, acutely emai'ginate a t th e extrem ity, with obtuse and en tire segments.
T h e cellules a re m in u te , th e intei-stices wide, forming a pellucid reticulation. T h e color
is a yellowish gre en, move or less inc lining to brown, having a silvery and glossy
appearance like th a t o f S r y um argenteum, which cannot well be represented m th e
drawing, and is particulai-Iy conspicuous in th e dry specimens. Some p lants, indeed,
which g i w on much exposed rocks, w an t th is appearance a ltogether, and a re o f a
deep purplish brown almost inc lining to black ; in eveiy s ta te much o f th e m a rg in of
th e leaf, and sometimes th e extrem ity, for on e -th ird o f th e way down, is diaphanous,
whitish, and, as i t were, scariosc.
