7. Tortula Mulleri, Bruch et Schimp. ; hermaphrodita, caule elongato dense folioso radiculoso- 

 tomentoso, foliis imbricato-patentibus rectis imbricatis siccitate imbricatis oblongo-ovatis obtusis concavis 

 margine reflexis costa purpurea in pilum subspinulosum canum excedente, capsula cylindrica subarcuata. — 

 Bryol. Burop. 



Hab. Northern and Middle Islands : shores of Waikare Lake, Colenso. Bay of Islands, J. D. If. 

 Port Cooper, Lyall. 



Foliage usually reddish. The bisexual inflorescence is not constant, but certainly present in our specimens. 

 Base of peristome tubular. Leaves less spreading than in the common British species T. ruralis, to which it is nearly 

 allied. — Found in Europe, and in the Falkland Islands. 



8. Tortula mnioides? Schweegr. ; foliis laxe imbricatis patnlis siccitate crispis undulatis ovato-lanceo- 

 latis acuminatis pellucido-marginatis. — Scliwagr. Suppl. I. 310. 



Hab. Northern Island, Colenso. 



Specimens few and barren, referred with doubt to T. mnioides, which we have not seen. — Leaves much 

 crisped and patulous when dry, distant, yellowish, of firm texture,_ very acute, and somewhat gemmiferous at the 

 apex. — Approaches Syrrlwpodon fasciculatus in aspect, but may easily be mistaken for a species of Milium. 



Gen. XVI. DESMATODON, Bridel. 



Peristomium simplex. Denies 16, bi-trifidi, crura tetragona, remote articulata, granulosa, plerumque 

 articulationibus singulis connexa, humida, erecta, sicca incurva vel sinistrorsum subconvoluta ; paullisper 

 hygroscopica. Calyptra cucullata. — Habitus Triclwstomi. Elorescentia monoiea : fl. mas. axillaris, gem- 

 mceformis. 



An imperfectly defined genus, intermediate between Tortula and Trichostomum. 



1. Desmatodon nervosus, Bruch et Schimp. ; caule humili, foliis patentibus siccitate convolutis 

 ovali-oblongis apiculatis concavis margine revoluto-reflexis, nervo valido superne incrassato excurrente, 

 capsula ovali erecta exannulata, operculo suboblique conico-rostellato, peristomii dentibus inaequalibus. — 

 Bryol. Burop. Didymodon nervosus, Hook, et Tayl. Trichostomum convolutum, Brid. 



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



This Moss, remarkable for the thickened nerve, varies much in the peristome, which is sometimes wholly absent 

 or (at the Cape of Good Hope, etc.) with the teeth evidently twisted, in which state it has been described as a 

 Tortula (see Muse. Exot.). Found in Europe and North America. Frequent on the sea-coast. 



Gen. XVII. TBICHOSTOMUM, Iledw., Brid. {ex parte.) 



Peristomium simplex. Denies 32, plus minus perfecti, per paria approximati, filiformes, tetragoni, 

 granulosi, crebre articulati, intorti (gemelli insequales et saspe trabeculis plus minus connexi). Capsula 

 oblonga, erecta. Calyptra cucullata. — Elorescentia monoiea vel dioica : fl. mas. gemmqformis. 



1. Trichostomum lingulatum,, Hook. fil. et Wils. ; caule brevissimo, foliis patentibus confertis ovato- 

 lingulatis obtusis subflaccidis evanidinerviis carinatis siccitate erectis, seta brevi, capsula rotundo-ovata 

 erecta, operculo conico-subulato. (Tab. LXXXIV. Big. 4.) 



Var. (3; foliis longioribus, capsula subcylindrica, operculo longius rostrato. 



Hab. Northern Island : Bay of Islands, J. D. II. Var. /3, Colenso. 



A more dwarfish species than the preceding, and of pallid hue. — Leaves rounded and obtuse at the apex, more 

 flaccid, very slightly reflexed in the margin, areola? rather larger. Inflorescence dioicous, and annulus wanting in
