THE BROAD PRICKLY-TOOTHED BUCKLER FERN. 241 
and entire. The form to which the name was first given was col- 
lected in Guernsey, by Mr. G. Wolsey. Some very similar forms 
are less decidedly tripinnate and others less glandular. We associate 
with the typal Guernsey plant others from—? Devonshire: Torquay 
(not glandular), J. Carton. Pembrokeshire: Castle Malgwyn, W. 
Hutchison. Denbighshire: Ruthin, 7. Pritchard. Dublin: Glen- 
druid, R. Barrington; Three-rock mountain, R. B. Kerry: Kil- 
larney, R. B. Donegal: Gweedore, R. B. 
14. tenera (M.). This is a very fine and elegant glandular form, 
nearly related to fuscipes (13), but more delicate in texture, and 
more divided. The stipes is pale chestnut brown behind, furnished 
towards the base with dark-coloured lanceolate scales, and abundantly 
glandular upwards, as also are the rachides and the veins of the 
under surface of the frond. The texture is extremely thin and 
delicate. The fronds are two to three feet high, ovate, tripinnate. 
The pinne are broad and caudately acuminate. The posterior 
pinnules of the two lower pairs of pinne are elongate oblong- 
acuminate, the rest-shorter and obliquely ovate, but also acuminate. 
The pinnulets are sessile below, adnate upwards, the basal ones 
generally obliquely-ovate, but the greater number are narrower, 
often somewhat falcate, and with a tendency to the development of 
an auricle-like basal anterior lobe; they are deeply-lobed or ser- 
rated, with acute mucronate not very prominent teeth. It has 
been sent to us from Windermere, by Mr. F. Clowes, and though 
similar in some respects to fuscipes, appears to be a distinct form, 
its texture, division, and manner of toothing furnishing its dis- 
tinctive marks. 
15. valida (M.). This form is stout, erect, rigid, fleshy-looking, 
becoming thick and leathery when dry. The fronds are large and 
broad, ovate in outline, bipinnate, or more frequently tripinnate. 
The stipes is stout, furnished not very abundantly with lanceolate 
scales, which are two-coloured but variable in intensity. The pinnæ 
are broad and rather crowded. The pinnules are divided almost to 
the midrib over the greater part of the fronds, and when these are 
large, quite so, in the case of the basal pinnules; they are oblong 
ovate, a little curved forwards, the lobes oblong obtuse, lobate-serrate, 
with bristle-tipped teeth. The venules each terminate near the
