MOSSES. 255 



Scholopendrium vulgare grows very fine in some sheltered sit- 

 uations. 

 Blechnum boreale is common everywhere. 

 Hymenophyllum Wilsoni is found in many dark fissures in the 



rocks in high wooded fells, generally near a stream. 

 Osmunda regalis is common and fine. 



Botrychium lunaria is pretty frequent on high mountain heaths. 

 Ophioglosum vulgatum is very scarce. 



In giving an account of the Ferns of Windermere, the import- 

 ant discoveryof Woodsia Ilvensis in Westmorland, although not in 

 the immediate neighbourhood of Windermere, ought to he men- 

 tioned. This rare fern was found by Mr. Huddart, the nursery- 

 man late of Waterloo Gardens, immediately opposite Bowness, where 

 roots of it may be obtained, and also of many other British Ferns. 



AH the British Club Mosses are found near Windermere. 

 Lycopodium clavatum grows on most of the higher fells; L. 



annotium has been found in Langdale ; L. inundatum is not 



unfrequent on the margins of mountain tarns ; L. alpinum 



grows on many heathy fell-sides ; L. selago in similar situations ; 



and L. selaginoides is common in rivulets in high situations. 

 Isoetes laustris is abundant in all parts of the lake, but rather 



difiicult to find, because it is nearly always in deep water. 

 Equisetum plaustre var polystachyon is the only uncommon 



Horsetail which has hitherto been found here. 



The common Mosses are abundant, but some species may be 

 found which are very scarce in Great Britain, and are only seen in 

 some alpine or sub-alpine districts. The Muscologist will be 

 delighted with this tribe of plants, their luxuriance in some 

 situations is truly wonderful. In the following list the species 

 mentioned have been found in fruit, excepting in those cases in 

 which it is specified that they have been found in the barren 

 state only. Some of the species enumerated are not uncommon in 

 mountainous countries, others are rare or critical species. 

 Andreoea alpina, rupestris ; Rothii on Red Screes, 111 Bell, &c. 

 Weissia verticillata, Whitbarrow.
