MwscL] FLORA OF NEW ZEALAND. 95 



tough, but slender, red below, yellowish above, glossy. Leaves from ovate-lanceolate in the lower part of the stem, 

 to oblong-lanceolate above, tapering in the upper part, subacute, their margins entire, concave ; nerve narrow, con- 

 tinued to the apex ; lamella? very narrow and indistinct, unless in a section ; when dry the leaves are incurved, rounded 

 at the back, and folded together at the edges. Capsule inclined or horizontal, elliptical when fully ripe, at first 

 nearly erect. Operculum in Lyall's specimens longer than the capsule. Calyptra absent. Teeth of peristome thirty- 

 two, white, very small and short as in P. Molina, Mont., which has narrower, more subulate leaves, more copiously 

 lamellate and a wider nerve. It is equally distinct from P. canaliculatum, Hook, et Arn. The male plant is very 

 short ; perigonial leaves spreading, widely ovate.

Hab. Northern Island : shaded woods ; Huiarau, Colenso. 



Stems 1 inch long. Seta 1| inch long, rather thick. Leaves crisped and tortuous when dry. Calyptra large, as 

 long as the capsule. Operculum half as long, reddish-brown, pubescent at the apex only. — A taller species than P. 

 compressum, Hook. fil. et Wils. (Hermite Island), with shorter, not subulate leaves, distinctly lamellate, and more 

 straggling when dry.— Plate LXXXVII. Pig. 3 :— 1, plants, natural size; 2, capsule; 3, portion of peristome; 

 4, calyptra; 5, leaf; 6, transverse section, and 7, apex of leaf : — all but Jig. 1 magnified. 



4. Polytrichum (Psilopilum) australe, Hook. fil. et Wils.; dioicum, caule brevi, foliis confertis erecto- 

 patentibus ovato-subulatis rigidulis canaliculatis integerrimis dense lamellatis siccitate erectis incurvis seta 

 breviuscula, capsula inclinata ovata ventricosa microstoma, operculo rostellato, calyptra brevi apice scabra 

 peristomii dentibus 16 exiguis albidis. (Tab. LXXXVII. Pig. 6.) 



Hab. Northern Island : Buahine mountains, Colenso. 



Discovered in Hermite Island, Cape Horn, whence the specimens, from having been mixed with those of P. com- 

 pressum in the collection, were overlooked ; they agree with those from New Zealand in the peristome, but have less 

 rigid and longer leaves.— Scarcely one inch high. Seta f inch long, stout, reddish. Operculum one-fourth of the 

 length of the capsule, which has a very small mouth. Calyptra small, half as long as the capsule.— Differs in 

 many respects from the preceding, and is more nearly allied to P. trichoion, Hook, et Wils, which has larger, 

 softer, cuspidate leaves, lamellated only in the upper part.— Plate LXXXVII. Fig. 6 :— 1, plants, natural size)

Subgenus 4. Ctphoma, Hook. fil. et Wils.— Capsula superne plana, inferne gibba. Peristomii dentes 32-64. 

 Calyptra subnuda. Polia argute serrata, basi vaginantia, rigida. 



5. Polytrichum (Cyphoma) Magellanicum, Hedw. ; caule ramoso, foliis patentibus recurvis rigidis e 

 basi ovata vaginante subulatis serratis, capsula inclinata vel horizontali oblonga semitereti, operculo conico- 

 rostrato, calyptra pilosiusoula.— Hedw. Sp. Muse. i. 20. M. Antarcl. pp. 132, 411. t. 59./ 3. 



Var. /3 ; caule gracili, foliis brevioribus erecto-patentibus siccitate erectis.

 Milford Sound, Lyall. Var. /3. Clay banks, Manga-Powhatu, Colenso. Stewart's Island, Lyall. 



Like P. alpinum in general aspect.— Height 2-4 inches or more. Calyptra reddish, naked, except a few scat- 

 tered hairs below, and a few bristly asperities at the apex. Teeth 64, very small, white, nearly horizontal. The 



plano-convex capsule and almost naked calyptra have escaped observation until recently, and perhaps P. giganteum
