This perfectly hardy species, popularly known in England as the 

 " Female Buckler Fern," or the " Marsh Shield Fern," is of a thoroughly 

 cosmopolitan character, as it is found in quantities in both hemispheres. In 

 Europe it extends from Norway to Spain ; in Cashmere it occurs at elevations 

 varying between 5000ft. and 6000ft., while it is stated by Beddome (who, in 

 " Ferns of British India," describes it under the name of Lastrea Fairbankii) 

 to be found in swamps on the Pulney Mountains at an altitude of 4000ft. 

 It is also a native of Cape Colony, Angola, Natal, New Zealand, Bermuda, 

 Japan, &c. It is quoted by Eaton as a very common Fern in marshes and 

 wet places, but sometimes also in dry ground from Lake Winnipeg, British 

 America, and North Brunswick to Louisiana and Florida. This Fern was 

 first noticed as an English plant by Ray, who, in his " Synopsis Methodica 

 Stirpium Britannicarum," mentions it as the Fllix minor palustris repens 

 (" Creeping Water Fern, or lesser Marsh Fern "). N. Thelypteris is a most 

 interesting Fern on account of its being found in various parts of the United 

 Kingdom, generally in boggy meadows and marshes, especially where the soil 

 is gravelly. It is commoner in Scotland than in England or Ireland. In the 

 latter country it is limited to the marshes of Glencree, in Wicklow, and 

 the neighbourhood of Neveruss, Killarney. In England it is found on Lear- 

 mouth Bogs, in Northumberland ; near Settle, in Yorkshire ; at AUesley, in 

 Warwickshire ; on Knutsford Moor and New Church Bog, near Over, in 

 Cheshire ; and on Oxton Bogs, in Nottinghamshire. It is also stated to have 

 existed formerly in Windsor Park and Sunninghill Wells, in Berkshire ; 

 in the valley below Caesar's Camp, on Wimbledon Common j in a bog on
