THE ROCK BRAKE. 
Cryptogramme crispa.— R. Brown. 
(Alt.osorus crispus.— Bernhardt.) 
This fern is also called “ the Parsley 
Fern,” from its general resemblance to 
Parsley. 
There are two kinds of fronds, the 
fertile and the sterile ; the former, erect 
with linear oblong pinnules ; sori mar- 
ginal, and eventually confluent. 
This dwarf elegant fern is found 
amongst loose stones (not limestone), 
on the sides of mountains, and in the 
North-West of England is so abun- 
dant as to look like hill-side pastures 
at a distance. It cannot be confused 
with any other fern. 
Exceedingly abundant on the moun- 
tains of Northumberland, Cumberland, 
Durham, and Westmoreland. Abun- 
dant on the hillside of Lothrigg Fell, 
at the Head of Windermere. It is 
also found near Lancaster, Settle, 
Ingleburgh, Cronkley Scar, Wensley 
Dale, Fountain’s Fell. In Derbyshire, 
Shropshire, Somersetshire, and Wor- 
cestershire. In Wales, in Carnarvon- 
, r . . shire, Montgomeryshire, Denbighshire, 
Merionethshire, and in Glamorganshire (though rare). In Scot- 
land it is found in almost every county ; whilst in Ireland it only 
occurs in Down, Antrim, and Louth. 
Abroad, it is a native of France, Italy, Spain, Germany, Nor- 
way, Sweden, Denmark, Lapland, Switzerland, Hungary, and at 
Sitka, in North-West America. 
Although a mountain fern, and found in Scotland at the height 
345° ^et, in Lancashire it flourishes almost at the sea level. ^ 
Several times I have received varieties, and have collected 
them myself, but none were permanent. There is, however, a
