only be searched at low water on this wild rocky coast. The ferns 
were very abundant and extended some distance into the caves 
even where there was but feeble light. Some of the caves are full 
of water even at low tide, having a passage to the sea, and in these 
were numbers of seals that darted out on being approached. 
3. bicrenatum, Stansjield. One of Messrs. Stansfield’s sports. 
The two basal pair of pinnae distant, the remaining touching each 
other, margin bicrenated. Length, 6 inches. 
4. brachiatum, Moore. Found in Cornwall by Mr. J. Herbert 
in 1874. Pinnae narrow, with blunt tips, the two lowest brachiate 
[i.e. distinct branches) and twice as long as those immediately 
above. Length, 1 foot. 
*5. capitatum, Clapham. Found in 1861 near Scarborough. 
Stem naked for the basal 5 inches, then the leafy portion divided 
into a capitate head 5 inches wide, the pinnules overlapping. 
Length 10 inches. I have raised many capitate seedlings from 
this variety. 
6. caudatum, Clapham. Raised 
from spores by the late Mr. A. 
Clapham, of Ramsdale Bank, Scar- 
borough. A very distinct fern, with 
narrow pinnae, the frond terminating 
in a long caudate (or tail-like) apex. 
Length, 6 to 8 inches. 
*7. decorum, Lowe. Found by Sir 
W. Jackson Hooker, and also by Mr. 
O’Kelly in the Burren district, 
County Clare. 8x1 inches. Nar- 
row and smooth. 
8. Hookeri, Lowe. Found in 
abundance in the Burren district, 
County Clare. I received it from 
the late Sir William Hooker many 
years ago, and again recently from 
Mr. P. B. O’Kelly, Glenarra House, 
Ballyvaughan. More than 2 feet in 
length, with short blunt pinnae. 
*9. imbricatum, Lowe. Found in 
1865, in North Wales, by the late 
Mr. Clift, of Birmingham, wdio sent 
me the original plant, which is still 
alive. A very distinct variety. The 
pinnae overlap each other as if tiled. 
Apex of the frond caudate. Length, 
8 inches. A variety named by Mr. 
Clapham, imbricatum Lowei, is 
rather larger and more imbricated. f

racteristic.
