grammatice, and those of the upper portion larger. A. acutifolia has 
much narrower leaves. 
А. ASPERULA (Mitten). Gracillima, ezspitosa, ramosa, foliis paten- 
tibus ovato-lanceolatis acutis enerviis margine superiore dorsoque 
papillis asperrimis, cellulis superioribus longitudine sy% latitudine 
3000 uncie metientibus, inferioribus in folii medio croceis oblongis, 
paululum majoribus. 
Hab. Australian Alps, D. F. Müller, No. 14, ex parte. Readily di- 
stinguished from all the allied species by the very papillose margin 
and back of its leaves. 
П. Dicranaces. 
1. PLEURIDIUM, Brid. 
P. GRACILENTUM (Mitten). Monoicum, habitu P. alternifolii, gracile, 
foliis inferioribus e basi ovali subulato-lanceolato-acuminatis, nervo 
subulam superiorem totam occupante, margine ad basin partis subu- 
latæ indistincte crenulato vel levi, cellulis inferioribus oblongis paral- —— 
lelogrammaticis superioribus minoribus, perichætialibus thecam non 
tegentibus patulis anguste ellipticis subulato longe attenuatis canali- 
culatis apice parce denticulatis integerrimisve laxe areolatis, theca in 
pedunculo brevi subglobosa leptodermi, operculo brevissimo, calyptra 
cucullata ad thecæ mediam descendente. DN 
Hab. West side of Tower Hill, Tasmania; Mr. Archer. Also in King 
George’s Sound, New Holland, Menzies. | | | 
Excepting that the perichetial leaves are less straight and bristly, in 
general appearance scarcely different from P. alternifolium, but its leaves 
are of a different form. 
P. TENELLUM (Mitten). Monoicum, habitu staturaque P. nitidi, fore 
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 ver} 
closely, excepting in the male inflorescence, which, has been observed 
on a single individual only. The substance of the leaves 18 firmer, апо 
the whole plant pale brown. It appears to be distinct, but require 
further examination in living specimens. 
2. Bruca, Schw.

B. mınura (Mitten). Monoica, perpusilla, brevicaulis, foliis patents 
lanceolatis angustatis, nervo percurrente, margine superne serru |
