T. Knightii (Mitten). Monoica, habitu statura coloreque T. North- 

 iance simillima, foliis siccitate crispatis humidis patentibus e basi pau- 

 lulum latiore subovata lanceolatis apice acuminatis comalibus sensim 

 ad apicem angustatis lanceolatis marginibus undulatis integerrimis 

 nervo concolori excurrente mucroiiatis, cellulis basi hyalinis elongatis 

 utriuque ad margines altius quam in medio adscendentibus subito in 

 minutas viridas obseuras transeuntibus, perichsetialibus longioribus 

 paululo latioribus, theca in peduneulo rubro cylindrica, operculo subu- 

 lato theca dimidio breviore, peristomio et flore masculo T. Northianee. 

 Hab. New Zealand, Colenso, Kerr, Knight. 



This is the T. ccespitosa var. of Hook. fil. et Wils. in Fl. New Zea- 

 land i but it is assuredly distinct from T. Northiana, Grev., in the much 

 narrower leaves with undulated margins.

A. APicuLATUM, Hook. fil. et Wils. Fl. Nov. Zeland. par. ii. p. 58, 

 t. 83. f. 1, ubi calyptra sub fig. 5 delineata delenda est et capsulae 

 apiculus in figuris 3 et 4 calyptram veram repraesentat. 

 Var. turgidum foliis internis turgide concavis longioribus. 

 Hab. Tasmania, Cheshunt, Mr. Archer. 



These specimens are so different at first sight from those from New 

 Zealand, from the turgid, inflated state of the perichaetial leaves, that, 

 relying on the figure, they were considered distinct ; but an examina- 

 tion of authentic specimens shows that the species has not been fairly 

 illustrated. The capsule is globose, without any apiculus ; and the api- 

 culus observable in the figures above quoted represents, much too large, 

 the minute calyptra. The calyptra figured more nearly represents one 

 of the lower leaves than any other portion of the moss. The margins 

 of the leaves are generally obtusely crenate at the apex.

S. princeps (Tortula, De Not. ; Barbula Miilleri, jB. ^ S.). 



Hab. Tasmania, on rocks and stones, the Hummocks, near Cleveland, 



and on rocks. Port Sorrell, Mr. Archer. 



Divided by Mr. Wilson (FZ. Tasmamca ined.) into three species, di- 

 stinguished from each other by the outline of the leaves ; but the struc- 

 ture is the same in all, and the differences appear of the same import- 

 ance as those observable in forms of S. ruralis and S. Icevipila.
