lobate. Sometimes the fronds are nearly normal in outline, cordate 
at the base and deeply crenated in an irregular manner along the 
margins; or occasionally slightly undulated. The upper surface 
is marked here and there with distant streaks of yellowish-green. 
It was found by Mr. W. W. Reeves, near Worthing in Sussex. 
49. salebrosum (M.). An elegant form allied to sinuatum (45) 
but having shorter fronds, which are sometimes subtruncate, some- 
times cordate at the base, attenuate at the apex, the margin not 
contracted but furnished with unequal rounded lobes projecting 
beyond the general outline, the whole including the lobes being 
erenately toothed. It was found in Guernsey by Mr. James. A 
large form having something of the same character found by Mr. 
Elworthy, has been called obtusilobatum. 
50. projectum (M.). A large and singular form, of normal size, 
the base cordate, or subsagittate, the margin: plane or subundulated 
and furnished with distinct broadish acute lobes half an inch 
long or more projecting therefrom ; the apex is attenuate. The best 
form we have seen, subundulate and with more numerous lobes, and 
subsagittate at the base, was found at Ilfracombe by Mr. J. Dodds ; 
and others have been sent by Mr. Elworthy from Nettlecombe ; by 
Mr. J. Crossfield from Kendal ; by Mr. Sclater from Newick ; by Mr. 
Bloxam from Tenby ; and by Mr. Stansfield from Scarborough. 
öl. resectum (M.). This is a fine variety, of normal size, remark- 
able from the absence of the usual auriculate lobes at the base of 
the frond, which are truncate, and somewhat rounded off, thus pro- 
ducing a kind of lance-shaped outline. The margin is slightly but 
prettily undulated and sinuately lobed, and the lobes are crenately 
toothed. The plants have a tendency to merge into sinuatum (45). 
It was found at Littlehampton, Sussex, by Mr. Wollaston. 
52. retinervium (M.). The fronds of this variety are about nine 
inches high, dissimilar, uneven in outline, subcordate or subtruncate 
at the base, sometimes multifid at the apex, the margin slightly or 
deeply lobed, sometimes in a sinuous manner and here and there 
contracted, the more normal parts obseurely crenated. The con- 
tracted and lobate portions are marginate. The fronds are blotched 
with pale green, almost amounting to variegation. The veins are 
much netted even in the more normal shaped fronds and parts;
