grammatic, and those of the upper portion larger. A. acutifolia has 



much naiTower leaves. 



A. ASPERULA (Mitten). Gracilliraa, caespitosa, ramosa, foliis pateu- 

 tibus ovato-lanceolatis acutis enerviis margine superiore dorsoque 

 papillis asperrimis, cellulis superioribus longitudine ywu-q latitudine 

 575V0 unciae metientibus, inferioribus in folii medio croceis oblongis 

 paululum majoribus. 



Hab. Australian Alps, D. F. Miiller, No. 14, ex parte. Readily di- 

 stinguished from all the allied species by the very papillose margin 

 and back of its leaves. 



II. DiCEANACEiE. 



1. Pleueiditjm, Brid. 



P. GRACiLENTUM {Mitteii). Monoicum, habitu P. alternifolii, gracile, 

 foliis inferioribus e basi ovali subulato-lanceolato-acuminatis, nervo 

 subulam superiorem totam occupante, margine ad basin partis subu- 

 latse indistincte crenulato vel Ifevi, cellulis inferioribus oblongis paral- 

 lelogrammaticis superioribus minoribus, perichaetialibus thecam non 

 tegentibus patulis anguste ellipticis subulato longe attenuatis canali- 

 culatis apice parce denticulatis integerrimisve laxe areolatis, theca in 

 pedunculo brevi subglobosa leptodermi, operculo brevissirao, calyptra 

 cucullata ad thecae mediam descendente. 



Hab. West side of Tower Hill, Tasmania ; Mr. Archer. Also in King 

 George's Sound, New Holland, Menzies. 

 Excepting that the perichsetial leaves are less straight and bristly, in 



general appearance scarcely ditferent from P. alternifolium, but its leaves 



are of a different form. 



P. TENELLUM {Mitten). Monoicum, habitu staturaque P. nitidi, flore 

 masculo gemmiformi minuto in foliorum caulinorum axillis, cellulis 

 foliorum paululum brevioribus firmioribusque. 

 Hab. Tasmania, Cheshunt, Mr. Archer. 



When dry, firmer than P. nitidum, with which it corresponds very 

 closely, excepting in the male inflorescence, which has been observed 

 on a single individual only. The substance of the leaves is firmer, and 

 the whole plant pale brown- It appears to be distinct, but requires 

 further examination in living specimens. 



2. Bruchia, Schw. 

 {S^mrledera^ Hampe.) 



B. MiNUTA (Mitten). Monoica, perpusilla, brevicaulis, foliis patentibus 

 laneeolatis angustatis, nervo percurrente, margine superne serrulato, 

 cellulis laxiusculis, theca suborbiculari-ovata acuta collo sensim at- 

 tenuato sessili erecta, calyptra apice rugulosa thecae tertiam partem 

 obtegente, flore masculo gemmiformi. 



Hab. Tasmania, sides of ditches, Cheshunt, Mr. Archer.
