320 LASTREA DILATATA. 



Hankeyan^, Moore. — Found by Mrs. George Henkey in 

 Cumberland. This is remarkably slender and elegant. Both 

 the pinnae and the pinnules are unusually distant from each 

 other. The pinnules are long and narrow, the lobes small and 

 finely dentate, and the whole so remarkably convex in form, 

 that the fronds cannot be flattened. A somewhat similar form 

 has been found near Aberdeen. Doubtfully distinct from 

 recurvifolia of Moore. 



Uncinella, Moore. — Found in Somersetshire. A very dwarf 

 variety. The fronds only from four to five inches in length. 

 The lamina of the fronds briefly ovate. Bipinnate and almost 

 tripinnate. The pinnules are peculiarly decurrento-confluent. 

 Dentation large. The teeth on the lobes, which they terminate, 

 have a marked tendency to become incurved.

RuGOSA, Tait. (Fig. 268.)— Found by Mr. Tait in Monkland 

 Glen. Length of frond two feet, width at the base eight 

 inches. A narrow-fronded very leafy variety, distinct on account 

 of its rugose habit. My thanks are due to Mr. P. Neill Fraser, 

 Canon Mills Lodge, Edinburgh, for fronds. 



CoNCiNNA, Moore. — Found in the west of Scotland. This 

 variety has a lamina nine inches in length on a six-inch stipes, 

 the outline being more or less oblong-ovate in form. Tripinnate, 

 with the parts small. The pinnules are stalked, and are sub- 

 falcate and acute. The lobes being small, linear-oblong, with 

 a few sharp teeth, which are most evident at their tips. The 

 anterior basal lobes most prominent. Sori small.
