I—L. рилтата GLANDULOSA— (PATE ХХ) іза large 
and somewhat erect growing plant, with much the aspect of a large broad Z. spinulosa, but differing 
from that in the int 
liate form of the seales of the stipes, in their frequently being two-coloured, in 
the glandular-fringed indusia, and in the subercet, not erceping caudex. ‘The fronds grow from a fo 
and a half to three or four fect high, and are of an oblong-lanceolate figure in the larger plants, or 
ovate-lanccolato in the smaller ones, arly erect around the stout pale-coloured erown which 
terminates the thick ascending tufted caudex. They are bipinnate above, tripinnate below ; the pinne 
ascending and twisted, so as to form nearly a horizontal plane, laneeolate-ovate, the longest nearly six 
inches long, and about two inches broad just above the base ; pinnules lanceolate-ovate, or pyramidately 
ovate, acute, 
reraging nearly an inch in length over the greater part of the frond, the posterior ones 
on the lower pinnae long 
st, those of the lowest pinnse being an inch and three-quarters long ; the lower 
ked, the rest successively decurrent, adnate, confluent. ‘The pinnules are pinnatifid almost 
down to the midvein ; their lobes obloı 
adnate, incised or toothed, the serratures all tipped by a 
bristle-like point. Tho stipes varies from about one-third to one-half the entire length of the frond, and 
is clothed sparingly upwards, more thickly near the base, with ovate bhuntish, and ovate-lanceolate 
pointed scales, which are generally of a pale brown, scarcely tawny, some having and others wanti 
darker central streak, many of them, as seen in the grow 
plant, becoming a good deal appressed 
to the stipes, whilst a few remain spreading; but this appears to be far less obvious when dried. 
"The stipes, rachides, and under surfa 
се of the fronds, are densely covered with stalked glands. The 
fructification is copious over the whole frond, and forms two I 
on each of the smaller pinnules, 
ог on the lobes of the larger ones ; and the sori are covered by indusia, which are fr

Bennett, near Lydbrook, in the Forest of Dean, Gloucestershire ; and was sub

same place by Mr. W. H. Purchas, of Ross, It has since been found in

by Mr. H. Doubleday. We are indebted to these gentlemen for both specimens and livi

near Croydon, Surrey, by Mr, J. Hutcheson; and (2) another glandular Fern, gathered by himself at 
Barnes, Surrey, where we have also found it sparin 
y. The latter is certainly not identical with 
the Dean Forest and Epping plants, but approaches them closely in some respects, differing chiefly in 
its laxer habit, and less elongated fronds, and in the presence of more nume pointed lanceolate 
and dark-centred scales among the br 
ог ones on the stipes. We have gathered another glandular 
Fern at Hampstead, Middlesex, somewhat different, especially in the scales, which are lon 
narrow, and in the more obtusely ovate form 
the pinnules. This latter, with that from Barnes, 
supplies the connecting links between glandulosa and dilatata ; the most ordinary looking forms of 
the latter being moreover sometimes quite glandular 
Besides the varieties already mentioned, which we consider the most distinct and important, thero 
are many other, indeed almost endless, modifications of this Fern, many of which, however, we believe 
to bo permanent forms, although they have not all been proved by cultivation. ‘The following is a brief 
summary of the various forms which have come under our observation

in fact, two fronds are, as it were, borne on one stipes. 16 is, however, rarely that more than one or two 
fronds on a plant are affected, and the variation is not constant.
