LASTREA DILATATA. 



Stansfield, of Todmorden. Mr. Monkman has found this variety, 

 more than any other, to be liable to the attacks of the green 

 fly, which, if not closely watched, quickly destroys the foliage. 

 In a Malton atmosphere the variety is only semi-persistent. A 

 very fine and really interesting Fern. A Scottish form. The 

 stipes and rachis forked, so as to produce a branched frond.

Glandulosa, Moore. (Fig. 239.) — First discovered in a 

 boggy portion of Ankerbury Hill, near Lydbrook, in the Forest 

 of Dean, Gloucestershire, and subsequently near Windermere 

 by Mr. F. Clowes; near Linley, Broseley, Shropshire, by Mr. 

 G. Maw; at Barnes, Surrey, by Mr, T. Moore; at Hastings by 

 Mr. J. Stidolph; and in Epping Forest, Essex, by Mr. H. 

 Doubleday. A large-growing, almost erect-habited form, with 

 tall robust fronds, not unlike a large and broad spinulosa, yet 

 diifering in having the scales on the stipes more lanceolate in 

 form and two-coloured, and in the indusia which covers the 

 spore-cases being glandular fringed. Caudex somewhat creeping. 

 The stipes varying from one third to one half the length of 

 the entire frond, scaly, thickly so near the base, and sparingly 

 upwards. The stipites, rachides, and under surface of the 

 fronds covered thickly with stalked glands. Length of fronds 

 from twenty-four to forty-eight inches, oblong-lanceolate in form 

 in the fully-developed fronds. Tripinnate below, bipinnate 

 above. Pinnae ascending, and twisted almost horizontally, the 

 lower ones unequally deltoid and wide, above lanceolate-ovate, 

 two inches broad near the base, and six inches in the longest.
