Apparently a distinct species, somewhat allied to G. apocarpa, as to the fruit; but in the foliage, more nearly 
to G. trichophylla.

2. GRIMMIA falcata, Hook. fil. et Wils.; caulibus laxe cespitosis pendulis, foliis falcato-secundis 
lanceolato-subulatis crassinerviis canaliculatis integerrimis, theca immersa subsessili turbinata, operculo 
rostellato. (Tas. CLI. fig. VIIL.) 
Has. Kerguelen’s Land; on rocks and stones near a small waterfall. 
Caules laxe ceespitosi, 1-3-unciales, penduli, flexuosi, ramosi, rami subincurvi. Folia imbricata, falcato-secunda, 
lanceolato-subulata, carnosa, integerrima, canaliculata, lateribus inflexis, nervo lato crasso excurrente, lurido-viridia, 
inferiora seepe aqua destructa, nervo solo residuo, areolis minutis subquadratis. Perichetialia ovato-lanceolata, 
acuminata, thecam superantia. Vaginula conica. Theca subsessilis, subrotunda, ore patulo, brunnea. ۵ 
nullus? Peristomii dentes magni, apice subperforati, incurvi, dorso trabeculati, rubri, siccitate recurvi. Operculum 
hemispheericum, rostellatum, capsula brevius. Calyptra fusca, mitreformis, brevis. Flos masculus in axillis ramu- 
lorum ad basin ramuli fructiferi. Antheridia plurima, eparaphysata. 
Allied to Grimmia apocarpa, var. rivularis, but very distinct in its falcate leaves, and broad thick nerve. As in 
that species, the columella generally falls away with the operculum. The short fertile branches are often clustered 
two or three together. ;

Ab exemplis Britannicis his notis differt: caulibus longioribus pluries ramosis; foliis magis patulis, subre- 
eurvis, perichzetialibus apice diaphanis, nervo angustiore; capsula majore. 
This moss affects the same localities in the Antarctic regions that it does in England.

Var. 1, foliis subpiliferis suberectis.

Var. 3, foliis caulinis angustioribus, perichetialibus preegrandis obtusis.

Has. Falkland Islands; var. 1, slate rocks near the sea. Var. 2 and 3, Kerguelen’s Land, on rocks, 
alt. 500 feet. Hermite Island, Cape Horn; on trap rocks near the sea. 
The most striking feature of the three last named varieties is the large obtuse pericheetial leaves. The habit 
and place of growth are similar to what this moss inhabits in Britain. à
