THE COMMON POLYPODY. 65 
5. serrulatum (Woll.). This variety has the teeth of the lobes 
minutely serrate, which is its chief peculiarity, so that it does not 
deviate widely from the normal states of the species, though it has 
proved constant under cultivation. This has been found in—Devon- 
shire: near Ottery St. Mary, G. B. Wollaston. Yorkshire: near 
Malton, C. Monkman. Carmarthen, Wales. 
6. marginatum (Woll.). This form of variation consists in the 
splitting, in a very irregular way, of the epidermis on the margins 
of the lobes, one portion, generally on the under side of the frond, 
receding as it were towards the midvein; the lobes themselves are 
irregularly lacerate or serrate. Kent, G. B. Wollaston. Winder- 
mere, F. Clowes. 
7. auritum (Willd.). This variety has at the base of the lobes on 
their anterior side, that is next the rachis on the upper margin, a 
distinct lobule or auricle, forming a kind of ear, from which it takes l 
its name. The auricle is variable in respect to its appearance and 
size. Windermere, F. Clowes. Another aurite form with more 
acute lobes, is found by Mr. Clapham at Settle. [Plate II B.] 
8. compositum (M.). This, so far as yet known, is a small growing 
variety, and combines peculiarities belonging to several other kinds ; 
the lobes are crowded, broad and overlapping at the base, deeply 
lobed, the lobules becoming shorter upwards so as to give the lobes a 
pyramidal or in some cases a somewhat hastate outline ; the anterior 
basal lobule is much larger than the rest, as in auritum; the upper 
lobes are less deeply divided but sinuated, as in sinwatum ; while the 
“division of the lower lobes in some degree resembles that of semi- 
lacerum, only they are broadest at the base. It is a very distinct 
and peculiar form; and was found near Ilfracombe, by the Rev. 
J. M. Chanter. A similar plant, probably the same, has been found 
by Mr. Elworthy, near Nettlecombe. 
9. cristatum (M.). This variety has the points of all the lobes 
multifid-crisped, and the apex of the frond itself more or less ramose, 
with the branches crisped and tasselled. It is an exceedingly pretty 
and distinct variety, hitherto constant in cultivation ; and was received 
“from a correspondent in Ireland, by Mr. Sim of Footscray. A much 
less marked form of the same character, but which has not proved 
constant, was found in the Isle of Man by Dr. Allchin. [Plate IV.]
