88 ME. W. MITTEN ON THE MOSSES OF 



Very much like /S. Loxensis (Hypnura), Ilook., but with a leaf of a 

 different form. 



** Isotlieciv/m. 



S. cochlearifohus. (Hypnum, Schw.) 

 Hob. Tasmania, on rocks, Elliott Rivulet. 



S. deflexus. (Hypnum, Wils. MSS, olim.) 



Hab. Tasmania, on the ground, rivulet at Cheshunt, and on logs, 

 Western Creek, Mr. Archer, 



S. gracihs. (Isothecium, Hool.fil. et Wils.) 



Hah. Tasmania, stones in rivulets, Jackey's Plain Creek, Mr. Archer. 



S. ANGUSTATUS {Mitten). Dioicus ? ramis inferne simplicibus foliis 

 appressis superne in frondem planiuscularo dendroideam dense bi- tri- 

 pinnatam divisis, foliis patentibus subcorapressis anguste ovali-ellip- 

 ticis brevi-acuminatis acutis concavis lateralibus complicatis integerri- 

 mis breviter binervatis, ramulinis anguste ellipticis superne serrulatis, 

 cellulis angustis omnibus conformibus, perichsetialibus e basi ovata 

 convoluta subuiatis patentibus, theca in pedunculo brevi ovali hori- 

 zontali, peristomio normali ? 

 Hab. New Zealand, near Wellington, Stephenson ; and elsewhere, Kerr, 

 Lyall, Knight. 



Stems one and a half to two inches in height ; habit that of S. {Iso- 

 thecium) arbuscula and S.{I.) dejlexus, but smaller in all its parts ; leaves 

 more narrow. Only one perfect peristome has been seen, and this 

 appears to be normal. 



S. lagurus. (Leucodon, Hook. Muse. Ewot.) 

 Hab. Tasmania, Cheshunt, Mr. Archer. 



The peristome of this moss is simple by reason of the external teeth 

 being obsolete.

*** Plagiothecium, Scliimp. 



S. Donianus. (Hypnum Donianum, Smith.)

 substance of its leaves it differs. 



S. auriculatus. (Hypnum, Mont.) 



Hab. Tasmania, on logs. Western Creek, Mr. Archer. 



***** Achyrophyllwm . 

 Rami erecti, elongati, ramosi. Folia lata, nitentia, concava, paleiformia.
