ON TWO ADDITIONS TO THE BRITISH MOBS-LIST. 47 



field) for last October. This species, if such it eventually prove to be, 

 is a Westmoreland as well as a Yorkshire plant, having since been 

 found in the neighbourhood of Levens, near Kendal, by Mr. Barnes, 

 who remarks that he has noticed it as peculiar for several years, 

 and never known exactly what to call it. A small specimen which 

 he sends appears to be identical in all essentials with Mr. Wesley's 

 Teesdale plant, but a little shorter and more robust. From small 

 forms of B. pollens, which Mr. Barnes also sends, and which bear a 

 good deal of resemblance to it, the new moss may be readily 

 known by its denser tufts ; while the leaves of B. pallens are also 

 distinctly bordered with several rows of narrow cells, their apices 

 serrulate and the nerve excurrent. Its aspect is that of B. 



barbatum, Wils. 



Dr. Braithwaite has been kind enough to send me a couple of 

 morsels of a Bryum which he has received from Dr. Lindberg, 

 under the name of B. calcareum ; one of them gathered in Ireland, 

 the other in Norway. On examination I am unable to distinguish 

 either of these from B. pallens, of which I should be disposed to 

 consider them merely starved or dwarfed forms ; one having male 

 flowers and the rosy-pink or reddish tint so frequent in that 

 species, and in B. turbinatum when growing on bare surfaces in 

 b °ggy places. I have seen just such near Oxford. 



Fissidens serrulatus, Brid. — Mr. Curnow sends from Cornwall a 

 couple of forms of Fissidens polyphyllus, which grows in several 

 places about Penzance, and therewith a third specimen for 

 examination, which I have no hesitation in referring to F. 

 serrulatus. This highly interesting addition to the British 

 cryptogamic flora, not hitherto suspected to be a native of this 

 country, was long supposed to be restricted to Madeira and the 

 neighbouring islands, but found some years ago in Portugal.

 difficult to discriminate, including F. Homschuchii, Mont. (F. 

 serrulatus, Hornsch.), F. tylvaticus, Griff. {F.javanicus, Dz. & Mlkb.), 

 and other tropical species. F. Welwitschii, Duby., another near 

 relative pertaining to South-west Africa, has lately been found in 

 Portugal, and appears very close to /*'. poh/p/u/llus. At the 

 Jime of the publication of 'Bryologia Britannica' English 

 botanists were but little acquainted with these, and Wilson 

 was induced to unite together his own polyphyllus, F. serrulatus, 

 ana F. itsplenioides, Hedw. Between the two former there are, 

 jowever, differences enough, and no biwologist, with our present
