 Hab. Tasmania, on dead wood, Mr. Archer and others. 



Nearly allied to D. Billardieri, but with somewhat the aspect of 

 jD. refiexum. 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 perichsetial leaves are also furnished with a 

 bristle-like point, which seems wanting in D. Billardieri.

D. TORauATUM {Mitten). D. pyriformi omnibus partibus maxima 

 simile sed foliis a parte inferiori magis gradatim subulatis et lamina 

 altiore a nervo distinguenda, cellulis in parte laminae superiori qua- 

 druplo minoribus, foliis perichaetialibus internis basi tenerionbus, 

 peduneulo siccitate spiraliter torto. — Campylopus pallidus, ex parte

So very much does this species resemble D. pyriforme (Campylopus, 

 Schultz), that it may readily be passed over as a state of that species, 

 having the same soft appearance. The species referred to in the ' Flora 

 of New Zealand ' as the typical form gathered by Prof. Jameson in the 

 Andes of Quito is a more robust species, with stiffer and less finely 

 attenuated leaves, and a capsule rough at the base. Dicranum nodosum, 

 Beauvais in Hb. Hooker, is a much larger moss, with leiaves having a 

 longer base, stouter nerve, and stiffer habit ; it is in all probability syn- 

 onymous with Campylopus nivalis, Brid. If Campylopus could be de- 

 fined so as to distinguish it from Dicranum, there would be no necessity 

 to alter the name of the present species ; but it seems impossible to 

 separate them in an extensive herbarium, notwithstanding the difference 

 in the aspect of some of the species, and, there being a Dicranum pal- 

 lidtim from N. America previously published by Bruch and Sehimper, 

 an alteration has become unavoidable.
