POLYTRICHUM TENUIROSTRE.
Polytrichum caule brevi simplici, foliis patentibus lanceolatis
obtusis subflexuosis canaliculatis integerrimis,
nervo subangusto lamellato, capsula ovata, operculo
longe-subulato. ( T a b . LXXV.)
Hab. In sinu Dusky Bay dicto, apud Novam Zeelandiam.
U. Menzies, 1791.
Caules cæspitosi, semipollicares, simplices, erecti, rigidi. Folia
sublaxe imbricata, patentia, nigro-fusca, carnoso-membranacea,
subflexnosa, lanceolata, obtusa, canaliculata, omnino integerrima,
nervo satis angusto, e lamellis longitudinalibus
4 v. S. Seta pro ratione plantæ longa, bipollicaris et ultra,
rubra, superne flavescens. Capsula exacte ovata. Operculum
longe-subulatum, capsula paulo brevius, subobliquum. Peristomium
dentibus triginta duo, ad apicem membrana horizontali
pallide flavescente conuexis. Calyptram non vidi.
I regret much the not possessing the calyptra of this species,
which iu its leaves comes nearest perhaps to Polytrichum hercy-
nicim, but in other particulars is very different. Indeedits quite
entire leaves, (of which the texture is like that of the last-mentioned
species and P . undulaturn and angustatum,) together with
the narrow nerve, exactly ovate capsule and subulate lid, will
keep it distinct from any other with which I am acquainted.
