than in either of the above species ; its pedicel, however, is tubercu- 

 late on the upper part only. 



Miiller (Synop. Muse, frond. 2, p. 272) unites H. Jiamatum with H. 

 scaberrulum, but according to authentic specimens from their authors, 

 they are distinct.

Hab. Lord Auckland's Islands. 



A variable and widely distributed moss, found in New South Wales, 

 Tasmania, New Zealand, and Auckland's Islands, but rarely in fruit. 

 Small in size, and of a color varying between pale green, rufous, and 

 dull yellow ; ramification variable, usually fasciculately branched ; the 

 branches mostly short, closely, pinnately, and bipinnately ramulose, 

 sometimes considerably extended, simply and distantly pinnated, as 

 in the figure above cited (where the plant is represented too large) : 

 stems somewhat firm, elastic, reddish, conspicuous through the leaves, 

 which are always more or less papillose, varying in this respect in 

 different leaves on the same branch. 



Hypnum acutifolium, Hook. fil. & Wils. {Hyp. extenuatwm, Brid. ?) 

 with leaves gradually, not abruptly filiformi-acuminate, may be a form 

 of this species. Hypnum tanytrichum, Mont., is a nearly related spe- 

 cies, but has julaceous branches, and broadly obovate, more membra- 

 nous leaves, with a closer and more linear areolation.
