4. Dicranum angustinerve (Mitten, in Journ. Linn. Soc. ined.) ; “ dioicum, D. Billardieri simile, 
caulibus brevibus ramosis, foliis patentibus subsecundis e basi subovali elongata sensim angustatis nervo 
angusto percurrente dorso marginibusque apicem versus serrulatis cellulis elongatis angustis alaribus 
oblongis quadratisque flavide fuscis in massam quadratam utrinque dispositis, pericheetialibus convolutis 
internis vaginantibus subito in acuminem brevem setiformem angustatis, theca in pedunculo breviusculo 
semiunciali arcuata inclinata basi strumosa, peristomii dentibus rubris dicranis.” (Tas. CLXXI. Fig. 9.) 
Has. On dead wood: Cheshunt, Archer. Gathered also by Mr. Gunn, and communicated amongst 
some other Tasmanian Mosses by Mr. J. Nowell. 
“ Nearly allied to D. Billardieri, but with somewhat the aspect of D. reflexum, C. Mueller. It differs from D. 
Billardieri in the form of the wider portion of its leaves being more elongate, and the narrow upper part being 
shorter. The internal perichztial leaves are also furnished with a bristle-like point, which seems wanting in 
D. Billardieri.” Mitten, l.c.—PrATE CLXXI. Fig. 9; 1, cauline leaf; 2, perichzetium ; 3, capsule; 4, teeth :—
