40 ENGLISH BOTANY. 



Cheshire from the Rev. W. W. Newbould ; Godalming, Surrey (H. C. 

 Watson and Henry Bull). Mr. Moore gives stations in Kent, Surrey, 

 Sussex, Somerset, Devon, Cornwall, Monmouth, Hereford, Warwick- 

 shire, Gloucester, Oxford, Worcester, York, Pembroke, Denbigh, 

 Kirkcudbright, Stirling, Galway, Clare, Waterford and Guernsey. 



Of var. y the typical Cambricum was originally found in a wood 

 near Dinas - Powys" Castle, Cardiff, Glamorganshire. Said by 

 Mr. Lowe to have been found recently in a wood near Maccles- 

 field, Cheshire ; also reported from Kidderminster, Mill Dingle, 

 Beaumaris, Conway Castle, Ambleside, and Antrim. A fertile form 

 of it was found at Goderich Castle, Herefordshire by Mr. W. 

 Bennett, from whom I have cultivated specimens. Forms still less 

 divided I have from Killarney, and it has been observed in various 

 parts of Ireland, especially Kerry, Clare, and Wicklow. In the south 

 and west of England. 



England, Scotland, Ireland. Perennial. Summer, Autumn. 



Var. a has the rootstock varying from the thickness of a goosequill 

 to that of a man's little finger, usually creeping along the surface on 

 which it grows, to which it adheres by numerous branched densely 

 tomentose radical fibres ; it is branched, and the growing apex is always 

 in advance of the fronds, thickly clothed with pale reddish-brown scales, 

 which ultimately fall off, and leave the rhizome smooth and green. 

 Upon this part of it there are elevated warts, the top of which exhibits 

 a circular depression ; this is the scar left by the stipes which have 

 separated from the rootstock by an articulation. The scales with 

 which it is covered are remarkable for adhering by a large surface, so 

 as to be peltate, they are dentate on the margins and on the long apical 

 cusp ; the teeth are prominent and distant, spreading, or even a little 

 recurved at the point. The stipes is from 1 to 8 inches long, pale 

 green, cylindrical, with an inconspicuous green ridge on each side, 

 about as thick as a stocking wire, at first furnished with distant 

 lanceolate acuminate cuspidate brown scales, like those on the root- 

 stock, but soon becoming quite bare. Lamina usually more or less 

 channelled from the segments bending inwards ; 2 to 10 inches long 

 by 1 to 2h inches broad, dark green, paler and somewhat glaucous 

 beneath, with the veins more translucent than the rest of the frond, 

 and clubbed at the apex, unrolling at the end of May or first half of 

 June, but the sori are not completely developed till a month or six 

 weeks afterwards, when they are become yellow or bright orange, and 

 about the size of sago grains or larger ; they are often produced on the 

 apical portion only of the frond. The spores are pale yellow, oblong- 

 reniform, bluntly tuberculate. The fronds remain green until the
