V. Sparingly on Deelick Point, Brandon Head, and plentiful 
on the “ Three Sisters,” near Smerwick Harbour, from 350 
to 600 feet above sea-level : Hart 1884—gathered in the last- 
named locality, a storm-swept headland, by &.W.S. Abun- 
dant on a grassy summit (593 feet) on the Great Blasket 
Island (Praeger & Stelfox) Irish Nat. 1912, p. 161. 
This diminutive plant, which rarely exceeds two inches in 
height, was at first thought by its finder, Mr. H. C. Hart, to 
be O. lusitanicum Linn. It fruits, however, at the same time 
as the type and fully answers to text-book descriptions of 
var. POLYPHYLLUM Braun, showing a strong tendency to 
produce two fronds from the same rootstock—two out of 
three specimens gathered in Mr. Hart’s “‘ Three Sisters ”’ 
locality by R.W.S. having double fronds—while the spores 
although appearing smooth were seen to be covered with 
minute tubercules under the microscope.
