THE COMMON SCALE FERN. 207 
form. It is met with in various localities, and usually of large size, 
but being also sometimes found quite small, it is not a mere result 
of luxuriant growth, as has been supposed. "This is the var. sinuatum 
of Dr. Kinahan. We have seen this form, from—W estmoreland : 
Arnside Knot; Ambleside, Miss Beever. Cumberland: Keswick, 
Miss Wright. Brecknockshire: Crickhowel, J. R. Cobb. Devon- 
shire, R. J. Gray. Perthshire: Kinnoul Hill, near Perth, T. Wilcke. 
Kirkeudbrightshire: W. G. Johnstone. ` Clare, Dr. Allchin ; Black 
Head, R. Barrington. Galway: Ruins of King John's Castle, R. 
Barrington. West of Ireland, A. G. More. Carbery Island, Capt. 
A. S. H. Lowe. Waterford, J. R. Kinahan. [Plate XCIII B.] 
2. depauperatum (Woll.). The fronds of this form are variable ; 
some are irregularly sinuate-pinnatifid, some bifurcate at the apex, 
some tapering to an acuminate point, and others cornute; the seg- 
ments are very much depauperated, and occasionally almost wanting, 
in which case the fronds present the appearance of a sinuately winged 
rachis. The forms of this variety have been met with chiefly in 
Ireland, where it was first found by Dr. Allchin ; the most remarkable 
of them was gathered by Lieut.-Col. Buchanan at Kilkenny. 
3. ramosum (M.). A curious dwarf form, about a couple of inches 
in height, the fronds dividing into two at the top of the stipites, the 
branches resembling small normal fronds ; sometimes they are dilated 
upwards instead of lengthened, so as to become nearly obcordate in 
outline with the margin scarcely at all divided. It has been sent from 
Ilfracombe by Mr. J. Dodds.
