H.4B. Hermite Island, Cape H o rn ; var. ft. on moist rocks and at tlie roots of tre es; scarce.
Caules a-3-unciales, rami ascendentes. Folia falcato-seonndn, plicato-striata, serrulata, nervo ultra medium

This moss resembles B . admicum in everything but the scabrous seta, and the sernilate leaves ; the vai-, ft arain
approaches very nearly to some varieties of H. velutinum. “

In the Hookerian Herbarium we find a Brazilian specimen, apparently authentic, of B . lithophilum labeUed
“ supra lapides rivulorum in novo Fnbui-go ” , but consisting of two dilferent species mixed together; and as the
description m Fl. Bras, appears to have been draivn up from both, we append a diagnosis of the other s

Our specimens agree with B . lithophilum, except that tlicii- branches are more elongated and the leaves
faintly two-nerved at the base. A Brazilian specimen from Eaddi corresponds with the B . succedaneum, which is
allied to H. molle.

This variety is alhed to H. gracile, nobis, but differs in the reticulation of the leaves, and in thefr margins being
recurved at the base.

H a b . Hermite Is lan d ; on wet rocks by streams of water, generally in woods, grmving in patches, rare
in fruit.
AlUed on tlie one hand to E . tenuirostre, Hook. (Muse. Brit.), and on the other to B . leptorhynchum, Schwaegr.
From the first of these it differs in the longer more attenuated circinate leaves ; from the latter in its larger size and
in the elliptical shape of the lower part of the leaf, which is not reflexed at the mai-gin. The operculum, as in those
species, has a long slender beak and is somewhat longer than the capsule.
