FLORA OE NEW ZEALAND. 



\Musci. 



both species. Differs essentially from Bidymodon splacMif alius, Hook. (Muse. Exot.), and from the supposed var. 

 Weissia flaccida, Harvey, in the peristome and operculum. Besmatodon ambh/ophyllus, Montague, is described 

 with spathulate leaves and excurrent nerve, and is otherwise unlike our plant. An ambiguous form of this, found at 

 East Cape by Dr. Sinclair, approaches to T. Australasia in the leaves, but has a short capsule.— Plate LXXXIV. 

 Kg. 4 :— 1, plant, natural size ; 2, seta and calyptra ; 3, immature, and 4, mature capsule ; 5, portion of peristome ; 

 6, 7, leaves : — all magnified. 



2. Trichostomum phceum, Hook. fil. et Wils.; caule breviusculo, foliis erecto-patentibus rigidiusculis 

 lanceolato-oblongis carinatis acutis integerrimis siccitate crispulis margine planis opacis, nervo contmuo 

 pellucido, capsula oblonga erecta, perist. dentibus membrana basilari connexis. (Tab. LXXXIV. Fig. 5.) 



Hab. Northern Island : shores of Waikare Lake, Colenso. 



Specimens few and imperfect.— Foliage purplish-brown, of rather thick texture, more opaque than the con- 

 tinuous nerve, somewhat concave or conduplicate at the apex, elsewhere carinate, entire. Peristome defective, 

 teeth oblique, as in Tortula. Operculum (found loose) rather short.— Trichostomum Schimperi, Mont. Cent. 5, 37, 

 seems to be allied, but has obtuse leaves and the nerve discontinued.— Plate LXXXIV. Kg. 5 :-l, plants of 

 natural size; 2, capsule; 3, portion of peristome; 4, leaf; 5, apex of ditto -.—all magnified. 



3. Trichostomum muUbile, Bruch; foliis lineari-lanceolatis subcarinatis alis subundulatis siccitate 

 crispatis mucronatis margine subplanis, capsula ovali, operculo longe rostrato, annulo rmllo, penstomii valde 

 mutabilis dentibus brevissimis insequaBms.— Bryol. Murop. Trichostomum brachydontium, Bruch. 



Hab. Northern Island, Colenso. (A native of England.) 



This Moss is usually found near the sea-coast in Britain, and is rare in fruit. The leaves approach those of 

 Tortula caspitosa, but their texture is less fragile. The often abortive peristome renders it difficult at times to 

 distinguish this from Gymnostomum tortile. 



4. Trichostomum striatum? Bruch; foliis erecto-patentibus strictis ovato-lanceolatis acuminatis costa 

 crassa excurrente mucronatis. — Bryol. Burop. 



Hab. Northern Island, Colenso. 



Barren specimens only, intermixed with T. lingulatum, referred very dubiously as above.— Leaves yellowish, 

 rather distant, erect and incurved when dry ; margin plane. 



5. Trichostomum longifolmm, Brid. j caule erecto ramoso, foliis confertis erecto-patentibus subse- 

 cundis e basi lanceolata subulato-setaceis solidinerviis apice subdenticulatis, capsula erecta subcylindrica.— 

 Bridel, Bryol. Univ. v. I. p. 496 ? Didymodon, Fl. Anlarct. p. 408. 



Hab. Northern Island, Colenso. Wairarapa Valley, Auckland, Knight. 



Our specimens, few and incomplete, differ from those from Hermite Island, and described in the 'Elora 

 Antarctica,' in the shorter stem, the more elongated capsule, and the light green lax foliage ; but we find no essential 

 difference.— Inflorescence monoicous, as in T. pallidum, to which it is allied, but has more setaceous leaves, and the 

 nerve is thick and predominant.— A native of Euegia. 



6. Trichostomum laxifolium, Hook. fil. et Wils. ; caule brevissimo simplici, foliis distantibus e basi 

 ovata amplexicauli longissime subulato-setaceis patulis flexuosis solidinerviis canaliculatis integerrimis, 

 capsula oblonga subobliqua, operculo conico-subulato.— Dicranum flexifolium, Root Muse. Exot. t. 144. 

 Didymodon angustatus, Wils. MSS. 



Hab. Northern Island ; clay hills : Bay of Islands, /. B. II., Colenso. 



A change of the specific name is requisite, to avoid confusion.— Leaves very similar in form to those of the next 

 species, but more distant and patulous. Inflorescence monoicous. Annulus distinct. Capsule gibbous on one side, 

 suberect, narrower towards the mouth. Nerve of leaf predominant above, ill-defined at the base.-Eound at the. 

 Cape of Good Hope. Bidymodon cirrhifolium, Mont., from the Neilgherries, is scarcely different.
