This moss has considerable resemblance to Hypnum stramineum, but differs in having the leaves almost
piliferous, in the rostrate operculum and in the structure - of the peristome. It is also aUied to Hypnum cinitum,

The many points of correspondence between this moss and Bryum. vagans, nobis, have not escaped our notice.
The specimens being few and barren, we are unable to pronounce with confidence on the vahdity of the species.
I t differs from H. subbasilare in the acuminated distichous leaves and almost excurrent nerve. In habit it much
resembles H. denticulatum.

H a b . Hermite Island ; in moist woods, a t the roots of trees, very common, growing in tufts.
This species so much resembles H. mnioides, as to be scarcely distinguishable from it until gathered.
Ill our spechnens the leaves are by no means bifarious, as stated in the Musci Exotici, and are compressed only
when dry. The perichætial leaves are erect, almost piliferous, and nerved to the apex ; young calyptra coriaceous,
slightly ventricose, not subulate, at length dimidiate. The operculum is absent from all our specimens.
