FLORA 01 NEW ZEALAND. 



[Mwsci. 



and P. longisetum are only tall varieties of this species. It is found in South America, Euegia, and Lord Auckland's 

 Group. 



Subgenus 5. Phalacroma, Hook. fil. et 7Pifc.— Capsula teres. Peristoma dentes 32-64, Calyptra parce pilosa. 



6. Polytrichum (Phalacroma) dendroides, Commers. ; caule erecto triquetro dendroideo longissimo, 

 ramis fasciculato-fastigiatis subsimplicibus, foliis patentibus e basi vaginante ovata linearibus argute serratis 

 siccitate patulo-incurvis, capsula inclinata brevi macrostoma, operculo longirostri, calyptra parce pilosa, 

 peristomii dentibus M,.— Bridel, Mant. Muse. Bryol. Univ. v. 2. p. 112 (sub Pogonatum). Schwmgr. 

 Suppl. v. 2. p. 2. t. 151. Fl. Antarct.p. 411. 



Hab. Alpine and southern parts of the Northern Island, and in the Middle Island, Colenso, Sinclair, 



Lyall, etc. 



One of the most magnificent of Mosses; also a native of Fuegia.— Height 6 inches to 1 foot or more. Stem 

 branched near the top, several of the branches occasionally fertile at the extremity. Operculum longer than the 

 capsule, with an inclined beak. Calyptra reaching almost to the base of the capsule, sparingly covered with hairs, 

 often almost naked. 



Subgenus 6. Pogonatum, P. Beam., Bricl, Bruch et ScMmp.— Calyptra villosa. Capsula teres. 



7. Polytrichum (Pogonatum) tortile, Swartz ; caule simplici, foliis e basi teneriore amplexicauli 

 lineari-lanceolatis planis serratis siccitate laxe incurvis, capsula subtereti lineata suberecta, operculo convexo 

 rostellato.— Swartz, Fl. Ind. Occid. Bridel, Bryol. Univ. pt. 2. p. 108. Polytrichum convolutum, Hedw. 

 Sp. Muse. t. 20. P. subulatum, Menzies, Linn. Trans, v. i.p. 303. t. 6./. 5. 



Hab. Northern Island: clay banks, near the Bay of Islands, /. D. IL Tehawera and Hutt valley, 

 Colenso, Sinclair. 



A native of the West Indies, East Indies, and South America.— Height 1-3 inches or more. Capsule some- 

 times smoothly rounded, in other cases distinctly marked with about six prominent lines, not angles, and the colu- 

 mella also is winged. Henee it is doubtful whether this Moss should not rank under the next subgenus ; Bridel, 

 however, places it under Pogonatum, and notices the lineate capsule in the specific character. Original specimens 

 from Swartz, in Herb. Hooker, are too imperfect to satisfy us on this point, or even as to the identity of the New 

 Zealand specimens, some of which are so small as greatly to resemble the more common P. aloides, which has a 

 shorter operculum and the leaf not flattened nor at all pellucid : in this state it is P. subulatum of Menzies. 



Subgenus 7. Polytmciium, Bridel, Bruch et ScMmp.— Capsula angulata, apoptysi discoidea insiructa. Oper- 

 culum brevius rostratum. Calyptra villosa. Peristomii dentes smpius 64. Columella alata. 



8. Polytrichum commune, Linn. ; caule elongato, foliis patenti-recurvis lineari-lanceolatis longis ser- 

 ratis lamellis margine subbifidis pericliEetialibus membranaceis erectis vaginantibus, capsula tctragona, 

 onerculo brevirostri — Linn r Sp. PI. Bruch et ScMmp. Bryol. Europ. 



Var. /3 ; caule gracili, foliis confertioribus erecto-patentibus. 



Tar. 7; caule gracili, foliis remotis brevioribus.— P. remotifolium, Schwmgr. Supp. t. 154? 



Hab. Northern Island : Bay of Islands, Sinclair. Var. /3. Middle Island : Bligb/s Sound, Lyall, 

 (A native of England.) 



Subject to considerable variation in size and direction of the kwes.—P.formosum and P.gracile are nearly 

 allied, but well distinguished by Bruch. and Schimper. It is a native of all Europe, and North and South America. 



9. Polytrichum juniperinum, Hedw.; caule breviusculo, foliis patentibus subrecurvis e basi vaginante 

 lineari-lanceolatis margine inflexis integerrimis brevi-aristatis, capsula quadrangulari siccitate horizontal!, 

 operculo rostellato.— Hedw. Spec. Muse. t. 18. Bruch et ScMmp. Bryol. Burop.
