In submitting the following for publication in the Papers and 

 Proceedings, it is desired to add to the formal work an expression of 

 thanks to the Director of the Royal Herbarium at Kew for deter- 

 mination of many of the fungi and the two lichens. It is entirely 

 due to his help at a strenuous time that the descriptions have oeen 

 srailable for this year's volume. 



Pterostylis pracox, Liudb., is ralher common in Tas- 

 mania. Hitherto P. concinna, F. Ih-., has only been re- 

 corded from near Richmond, near Bellerive, and on a liill 

 at Wedge Bay. In the last two places it was growing with 

 P yrctcnx and in each in.stance, intermixed with typical 

 forms of the two, were intermediate specimens, apparently 

 hybrids. Prof. A. J. Ewart considers this intermediate 

 may be treated as a distinct spt-cies, and in a recent pub- 

 lication of the Royal Society of Victoria, from material 

 gathered in that State, named it PteraatyJis toveana in 

 honour of Mr. Tovcy, of the National Herbarium of vic- 

 toria, who has done excellent work in Australian botany. 



Amongst mosses : - - 



Pottui (Kii piittia) suhpln/scoiuitrioides, JirafJi. Ln 

 Proc. Linn. Soc, N.S.W., vol. 61, p. 582. — Very similar 

 to Pottia tnsmanica, lir'itli., on'v the nerve excurrenl in a 

 short stiff point and the margin less recurved. 



Port Esi>erance on ground. Also in Victoria. 



Probably not rare but overlooked from its small size 

 and resemblance to Wei^sia. 



In the same paper Dr. Brotherus describes a robust 

 Fixsidens gathered at Moss Valo as Fis<tideii'< ruilditisculus. 

 Broth, U.S., and he reduces our F. hpforlndns, CM., to a 

 variety of it. It is possible all students will not follow in 

 this. 



To our Hepatics may be added : — 



PlfiffinrhiJa iiritixii, St. — Shoots simple or with few 

 irregular branches, decumbent, about 1-2 cm. long, apex 

 rather circinate. Leaves imbricate, dorsallv secund, del- 

 toid, the doi-sal margin strict, the ventral strongly am- 

 pliate, apex of most leaves bifid, lobes acute, margin otlier- 

 wise plain, base not at all decuiTent, 1 mm. Cells 21 fi., 

 trigones rather large, convex. Sterile. 



On Fagus log, Pioneer track, Blue Tier (Weymouth). 

 Determined by Stephani.
