HYPNUM NECKEROIDES.
Hypnum caule erecto inferne denudato, sursum pinnato,
foliis undique imbricatis laxis ovatis obtnsis apice
serrulatis, nervo ante apicem evanescente, capsula ob-
longo-ovaía inclinata, ( T a b . LVIII.)
H a b . In sinu Dusky Bay dicto, apud Novam Zeelandiam.
D . Menzies, 1791.
Caulis digitalis vel palmaris, inferne repens, ferruginco-tomen-
tosus, demum erectus, basi apiceque indivisus, medium versus
pinnatim ramosus, ramis simpiicibus, attenuatis. Folia laxe
imbricata, patentia, molüa, ovata, obtusa, concava, apice minute
serrulata, nervo satis valido, dorso denticulato, ante apicem
evanescente instructa. Perichcetialia acuminata, enervia.
Setoe subaggregatæ, vix unciam longæ, crassiusculæ, fuscæ.
Capsula ovato-oblonga, intense fusca, inclinata. Ñeque operculum
ñeque calyptram vidi. Perislomii dentes flavi ; int,
perforati, processubus filiformibus duobus bis interjectis.
According to the fructification, this plant must be considered
as a Hypnum, although in general habit it accords best with the
genus Neckera, and particularly with that species which I have
denominated N . planifolia (T a b . XXIII.). Here however the
stems are not at all compressed, the leaves are decidedly nerved,
and the capsules of the two plants are widely different.
