384 Wilson's notes on British muscology. 



Algirianum, by which name it has been long well known on 

 the continent, while the older British muscologists supposed 

 it to be peculiar to the British Islands. See Bryol. Univ. 

 vol. ii. p. 593. 



The "variety with serrulated foliage," mentioned in Hook- 

 er's British Flora, vol. ii. p. T"7, is now ascertained to be a 

 distinct Moss, having a scabrous fruit-stalk. It is probably 

 H. Schleicheri, Bridel. Br. Un., vol. ii. p. 403, and has been 

 also found at Bowling-Bay, near Glasgow, and at Nant y 

 Fridd, near Wrexham. 



45. H. demissum, Wih. in Engl. Bot. SuppL t. 2740.— This 

 is the same Moss as that described in Hooker's Br. FL v. ii. 

 p. 79, under the name of H. favescens, the name demissum 

 having been substituted for one liable to produce confusion 

 from its resemblance to the names of already described 

 species. 



46. H. catenulatiim.-—T\\G. operculum is more properly 

 rostrate than " conico-acuminate," as it is described in the 

 British Flora. Foliage frequently secund ; the fruit ripens 

 about December ; but is extremely rare. Fertile specimens 

 have been gathered by the writer near Dolgelley, and near 

 Beddgelert, in N. Wales. 



47. H. inciirvatiim — This recent addition to our list of 

 British Mosses, was found by the writer in Helk's wood near 

 Ingleton, in 1837, and also near Kendal, on the road to 

 Ambleside. The fruit ripens about midsummer. 



48. H. circinnatum, Bridel, Br. Un.v. ii. p. 447. — A Moss, 

 answering to this description, was found many years ago by 

 the writer at Tyfry in Anglesea, and earlier still at Netley 

 Abbey by Mr Borrer. I have the same Moss from 

 Mr Arnott marked " Pterogonium nervosum, Montpelier." 

 Bridel is probably in error in referring this Moss to H. 

 strigosum, Hoffm. If it be not a distinct species (which I 

 think it is) its affinity is rather with H. alopecurum. In every 

 instance this Moss seems to have been found on calcareous 

 rocks. At Tyfry it is found with abortive pericheetia ; but 

 the fructification is altoorether unknown.
