Fig. 201. Р, v. Cambricum, 
CAMBRICUM (Fig. 201 and Appendix No. XLVI).—This very beau- 
tiful form was originally found in Wales, whence the name which 
means Welsh, but it has subsequently been found in several other 
places, some superior forms of it having been found in the Lake 
District. As our illustration shows, the normal plain-edged lobes 
are transformed into very deeply cut ones, and so widened as to 
overlap each other considerably. The fronds, too, are of thinner, 
papery texture, and are always perfectly barren. This is really 
the true plumose form of the species.
