NECKERA LONGISETA.
Neckera caule subpinnatim ramoso, foliis undique imbricatis
late ovatis acuminatis enervibus subintegerrimis,
seta longa, capsula oblongo-cylindracea, operculo
subulato. ( T a b . XLIII.)
H a b . Locis umbrosis, alsis montis Quindiu (Cordillera de los
Andes de Cuiidinainara). Humholdt et Bonpland.
Caules 3-4-unciales, decumbentes, ramosi, ramis subpinnatis,
sæpe erectis. Folia undique imbricata, erecta, flavo-viridia,
nitida, late ovata, apice acuminulata, sub summo lente minutissime
serrulata, omnino enervia. Perichcetialia longiora,
angustiora, magis acuminata, int. convoluta. Selce sæpe duæ
vel tres ex eodern ramo, biunciales, flexuosæ. Capsula oblongo
cylindracea. Calyptra dimidiata. Operculum subulatum,
capsula multo brevius. Peristomii ext. dentes 16,
pallide fusco-rufescentes, linea media longitudinali notati ; ini,
e ciliis perangustis, pallide flavis, bis alternantibus.
It must be confessed that this species comes Very near to
N . seductrix ; but its much larger size, longer fruitstalk and
operculum, together with the broader, more evidently acuminated
and entirely nerveless leaves, have induced me to keep it distinct.
With N. cladorrhizans in point of size it has a greater resemblance
: but that plant has its leaves, though likewise destitute
of nerve, of a different shape, not very correctly represented in
Hedw. Sp. Muse., and the “ rami apice radicantes” are never
found on the present species.
