134 BRITISH FERNS.— SUB-ORDER II. TRIBE 10 . 
Near Chepstow, except when growing with great luxuriance, the 
Hart’s-tongue is scarcely ever flat-fronded ; it is mostly undulate 
(or wavy), and often crisp. The beautiful form of Harts-tongue, 
known as crispum, is more abundant in Monmouthshire than in 
the whole of the rest of the United Kingdom. Within the last 
few years, not more than half-a-dozen miles from Chepstow, moie 
than fifty plants of “crispum” have been found ; and of these 
twenty-nine were discovered by the late Colonel Jones, between 
Caerwent and Shirenewton ; whilst on the opposite side of t ie 
Wye, near Tidenham, Major Cowburn has found nineteen, for 
which refer to section “crispum” in the descriptions of the 
varieties of Scolopendrium vulgare. 
Mr. Wollaston proposed the name, pseudo-mas, for one ot tnese 
species ; but Fee, in “ Iconogr. Nouv.” uses the same name for 
Filix-mas, whilst Aspidium paleaceum Don 1 rod. FI. Nepal 
has been adopted years ago for var. palcacea , Moore , N ature- 
Printed Ferns.” (This is the type of the normal form of the sub- 
evergieen fern under discussion, after the present species ; and no 
more appropriate name could be suggested.) 
THE MALE FERN. 
Nephrodium Filix-mas.— Richard. 
The normal form is large, but less elegant than N. paleaceum; 
texture of the frond thinner, colour paler and less shining ; 
partially deciduous. The fronds become broken at the ground by 
autumnal winds, and lie prostrate, whilst those of N. paleaceum 
retain their erect position until the spring fronds are ready to 
unfold. It is a common fern in this country.
