H a b . In alto de Aranda, locis frigidis, prope Pasto, (regnum
Novum Granatense) altit. 1360 hexapod. Humloldt et Bonpland.
Caules bi- triunciales, erec ti, flexuosi, hic illic dichotome divisi.
Folia undique vergentia, planiuscula, siccitate etiam e basi anguste
lanceolata, longissime subulato-setacea, flexuosa, pallide
viridia, apicem versus subserrulata, nervo latissimo paginæ fere
totam partem occupante. Perichcetialia reliquis similia, sed
lateribus involutis. S etoe aggregatæ, flexuosæ vel curvatæ.
Capsula flavo-fusca, inclinata, oblongo-ovata, sulcata, basi
strumosa. Operculum conico-subulatum rufo-fuscum. Calyptra
dimidiata, basi elegantissime ciliata, Peristomium dentibus
16, incurvis, rufis, fissis.
The specieshere described belongs to a curious family of Dicra-
7ZBJW,along with D.flexuosum, D. cygneum,and D. introflexum,
all agreeing in general habit, in the broad nerve of the leaf, and
in the ciliated border of the calyptra. From the former of these
it differs in the much longer and twisted nature of the leaves ;
from the two latter, in the striated and strumose calyptra ; and
still further from the last-mentioned species, in having the tips
of the leaves of one uniform colour with the leaves themselves, and
not at all diaphanous.
