7. Trichostomurn tetonm, Hook. fil. et Wils.; foliis confertis erecto-patentibus strictis e basi parum 

 dilatata setaceis carinatis integerrimis, nervo lato continuo, capsula oblonga obliqua ore coarctato operculo 

 conico-subulato. (Tab. LXXXIV. Kg. 6.) ' F 



Hab. Northern Island : Bay of Islands, J. D. II., Colenso, Dr. Sinclair. 



Closely allied to the preceding.— Leaves more setaceous, crowded, very little dilated below, sharply carinate to 

 the apex, lower ones reddish. Inflorescence, etc., as in the preceding.— The same Moss, as we suppose, is found in 

 Chili. A variety with more spreading leaves occurs in New Zealand {Colenso), approaching in aspect to T laxifo-

8. Trichostomum/™^, Hook. fil. et Wils. ; dioicum, tenellum, foliis laxis ligulatis canaliculus 

 obtusmscuhs patentibus arcuato-inflexis siccitate tortilibus, nervo subcontinuo, areolis superne minutissime 

 granulosis subpapillatis, capsula elliptica vix annulata, operculo conico-rostrato, peristomii dentibus scabri- 

 uscuhs membrana basilari connexis. (Tab. LXXXV. Tig. 1.) 



Hab. Northern Island : Bay of Islands, with Bryum duriusculum, J. I). H. 



Allied to T. inflexum, Br. et Sch., but differing in the peristome and in the obtuse granulated leaves not inflexed 

 at the margm—PiATE LXXXV. Fig. 1 : _1, plants, natural size ; 2, young capsule ; 3, ripe capsule ; 4, operculum ;

Gen. XVIII. DISTICHIUM, Bruch et Schimp. 

 Peristomium simplex. Denies 16, sub oris margine liberi, aequidistantes, lineares sen lineari-lanceo- 

 lati, articulati, Imea media ad basin products, integri vel pertusi, hie illic bicrures, cruribus incompletis 

 sffipius perforatis. Capsula oblonga, annulata. Operculum conicum, breve. Calyptra cucullata.— Folia 

 disticha, basi vaginantia, setacea. 



1. Distichium capillaceum, Bruch et Sch.; dense Ciespitosum, foliis e basi lanceolata vaginante seta- 

 ceis patentibus solidinerviis canaliculatis subintegris.-^. Europ. Swartzia capillacea, Hedw. Didy- 

 modon capillaceus, Hook et Tayl, etc. 



Hab. Middle Island : Otago, Lyall. 



Barren specimens with leaves much crowded and obscurely distichous, referred here with doubt If correctly 

 named, it is found all over Europe and North and South America. 



Gen. XIX. DLDYMODON, Bruch et Schimp. 



Peristomium pro capsulse longitudine breve, simplex. Denies 16, lineari-lanceolati, secus lineam me- 

 dium mtegn vel pertusi et bifidi, tenerrimi, fugacissimi. Capsula, etc. ut in Trichostomo. 



The separation of Didymodon, as a genus, from Trichostomum, seems to be questionable, but according to Bruch 

 and bchmrper is characterized as a natural group by the tender fugacious peristome, which resembles that of Ana- 

 calyptra or of Sermatodon, rather than of Trichostomum, with which it agrees in habit. 



1. IMymodon papillatus, Hook. fil. et Wils. ; laxe csespitosus, caule elongate ngidulo subramoso, 

 ramis erectis fihformibus, foliis trifariis patenti-recurvis ovato-lanceolatis acuminulatis carinatis subsolidi- 

 nerviis integerrimis utrinque papillatis pericliEetialibus convolutis, capsula oblonga erecta, operculo conico 

 subulate (Tab. LXXXV. Fig. 2.) 



Hab. Northern Island : Bay of Islands, /. D. II., Colenso (barren). 



Agreeing with fertile specimens from Swan Eiver, Australia.— Stems about an inch long, slender but rather 

 rigid and brittle. Leaves yellowish (reddish in age), distinctly trifarious, when dry erect and subsecund papillose
