420 Var. /3. foliis laxe imbricatis substriatis, theca ovata, operculo conico.

Hab. Herrnite Island, Cape Horn ; var. /3. on moist rocks and at the roots of trees ; scarce.

Caules 2-3-unciales, rami ascendentes. Folia falcato-secunda, plicato-striata, serrulata, nervo ultra medium producto, luteo-fusca, subspadicea, in var. (3. laete viridia. Seta semiuncialis, brunnea. Theca horizontalis, turgida, sub ore contracta, nifa. Perislomium externum ferrugineum, internum flavum.

This moss resembles H. aduncum in everything but the scabrous seta, and the serrulate leaves ; the var. /3 again approaches very nearly to some varieties of H. velutinum.

Hab. Hermite Island, Cape Horn, in bogs, very common by the margins of mountain lakes. In fruit amongst wet stones.

Also found, but barren, in Campbell's Island.

Hab. Falkland Islands, common in watery places, rare in fruit.

Apparently the moss mentioned by Gaudichaud under the name of H. aduncum, to which indeed it is nearly allied. It differs from H.fiuitans, in its very strong, often percurrent nerve. The leaves vary in length.

Hab. Kerguelen's Land, in bogs, not uncommon (barren). Hermite Island, Cape Horn, also in wet places.

22. Hypnum lithophilum, Hornschuch; ramis elongatis, foliis erecto-patentibus secundis siccitate erectis ellipticis acutiusculis (rameis elliptico-oblongis obtusiusculis) concavis margine reflexis tenuissime lineari-areolatis, pericheetialibus erectis. H. lithophilum, Hornschuch, in Endlich. et Mart. Flora Brasil. p. 84, in part.

Hab. Hermite Island, Cape Horn; with H.amosnum (barren).

In the Hookerinn Herbarium we find a Brazilian specimen, apparently authentic, of H. lithophilum, labelled "supra lapides rivulorum in novo Friburgo ", but consisting of two different species mixed together; and as the description in Fl. Bras, appears to have been drawn up from both, we append a diagnosis of the other species.
