Henmte Island, in rocky places near the tops of th e hills, scarce, abundant in frnit near the spray

In some respects cm- moss resembles B. tonwntosa. Hook. (Muse. Exot. 1 .19), which we scarcely consider to
be a distinct species, but the capsule is oblong and pendulous. '
The var. 3 may he distinct. I t resembles Hypnum elongatum, nobis. We have seen only the male inflorescence,
which is truly that of Bartramia.

Caules cæspitosi, 2-3 lia. longi, ramis brevibus apice coma incrassatis. Folia densa, e basi lineari longissime
attenuata, subflexuosa, carinata, integerrima, viiidia, nervo conspicuo sub apicem evanido, cellulis elongatis : perichætialia

This differs from Orthodontium lineare, Schwaegr. (Suppl. 1 .188), in the oblong suberect capsule, and in the
absence of teminal male flowers, thus deviating from the generic character proposed by Schwaegiichen. In the
inflorescence it agi*ees with the British Orthodontium gracile, Bruch and Schimper, but differs in the form of the
capsule and the stronger nerve of the leaf.

This \'ariety is connected with the ordinary states of the species by intermediate forms which JIathews gathered
at Casapi (Peru). The Hookerian Herbarium contains a Bryum, collected by Humboldt in South America, with
muticous convolute leaves, allied to this, but probably a distmct species.
