28 THE BRITISH FERNS. 
The pinne are distant, caudately acuminate. The pinnules are 
also distant, narrow-oblong, bluntish, pinnatifid, but the lobes shallow 
and short-toothed, the apical teeth being also small and short; the 
basal ones are placed close to the main rachis, so that the pinne 
are quite sessile. Found by Mr. Clapham, at Scarborough, and 
reported to be a very constant form under cultivation. Another 
slender form agreeing with this in the lax habit, sessile, caudate 
pinne, and narrow distant pinnules, has been communicated by 
Mr. Stansfield, of Todmorden. In this, however, as observed in 
the fronds of stenodon, the pinnules are of unequal length, with 
exaggerated teeth, but the Todmorden and Scarborough plants 
appear to be only different states of one slender distant-pinnuled 
variety. 
10. excurrens (M.). A curious form, the general appearance of 
which is that of molle, but with rather distant decurrent pinnules. 
Its peculiarity consists in the points of the pinnz, and sometimes of 
the pinnules and teeth, growing out into transparent hair-like points, 
which have the appearance of being an excurrent growth of the 
veins. It was found at Tunbridge Wells in 1853, and is cultivated 
by Mr. Wollaston. A plant of similar aspect, but without the 
excurrent points, has been found near Ilfracombe, by the Rev. J. M. 
Chanter. [Plate LV B.] 
11. pruinosum (M.). A singular variety, resembling the moderately 
developed growths of molle or trifidum, but the stipites and rachides 
are covered with small glands, which give them a hoary appearance 
somewhat resembling pubescence. It occurs with red stipites, at Tar- 
bet, in Dumbartonshire, where we gathered it in 1855; this form, 
resembling trifidum in its general aspect, having linear-oblong 
approximate acutish pinnules, has since continued constant to its 
peculiarities. A very similar plant was gathered by Dr. Allchin in . 
the Isle of Man. Another pruinose state of the Lady Fern, rather 
more lax in habit, with blunter shorter pinnules and the aspect of 
molle, but having pale green stipites, has been found by Dr. Allchin 
at Virginia Water, Surrey. 
12 odontomanes (M.). This is one of the smaller forms, growing 
from ‘a foot to a foot and a half high. The fronds are broadly 
lanceolate, and are remarkable for their long conspicuous teeth. The
