DIDYMODON SQUARROSUM.
Didymodon caule elongato flexuoso, ramoso, foliis undique
patentibus squarrosis longe lanceolatis flexuosis
carinatis serratis, seta elongata, capsula cylindracea,
operculo longe subulato. ( I ab. CL.)
Hab. In Nepal. Hon. D. Gardner,
Caules digitales et ultra, cæspites magnos densos efformantes,
erecti, fiexuosi, dichotome ramosi. Folia undique inserta, patentia
vel etiam recurva, et ita squarrosa, fiavo-vindia, longe
lanceolata, carinata, flexuosa, submarginata, inferne præcipue,
superne serrata, nervo ad apicem attingente percorsa; sub-
stantìa tenera, compacta tamen, areolis minutissimis. Ferì-
chcetialia reliquis similia sed magis elongata et setæ basin am-
plexantia, erecta. Seta terminalis, uncialis et ultra, flava.
cylindracea flavo-fusca. CaZyp/ra dimidiata. Oper-
culum longe rostratnm flavum, basi rufum. Peristomium e
dentibus 32, setaceis, per paria a rd e approximatis pallide
rufis. ^
This fine moss has the greatest resemblance in its leaves and
fructification to a very rare and minute one of our own country,
Didymodon flexifolium. It has a similar perichætium, and the
leaves are in like manner flexuose ; but then these latter are in
our present plant of a long lanceolate figure, gradually tapenng
to a point, whilst those of D . flexifolium are ovate and obtuse.
D squarrosum has certainly more the character ot a Triclio-
stomum than of a Didymodon; but to this last genus it .assuredly
belongs, having a truly dimidiate calyptra.
