distinct variety, and lias been found in Cornwall, 
■Devonshire, and Guernsey. The leaflets, broadly 
lanceolate, are so little divided that specimens have 
been mistaken for A. marinum ; and the upper leafits 
8 o run together at their base as to form one large 
terminal leaflet with many lobes. The fronds, also, in 
their outline arc less lanceolate and more linear-shaped 
than those of the species, and the spores nearer the 
Margins of the leafits. 
There are variations, not permanent, which only 
deserve a passing notice :— A. lanceolatum crispatum , 
^ith teeth of leafits undulating, so as to make the 
frond rather crisped ; laciniatum, in which the leafy, 
Part of each leafit is so deficient, that many are little 
®M>re than the mid-rib ; and elegans, slender-growing. 
Asplenium marinum (p. 47).—There are some 
°thor variations in form:— assimile, with leaflets 
lengthened and lobed as in A. caudatum, or eared as in 
A. auritum. Then there are crenatum, with leaflets 
frapeziform and scolloped or crenate: cuneatum, with 
leaflets having a wedge-shaped base; incisum, with 
fr*e lobes of the leaflets deeply incised; ramosum, with 
fronds branched or in pairs; bicrenalum, double and 
scolloped; caudiceps; elungatum, lengthened; inter- 
upturn, outline irregular; minus, same as trapezi- 
frrme; ramo-trapeziforme, frond trapeziform; sub- 
pinnatum, almost doubly pinnate. 
Asplenium buta-mukaeia (p. 51).—The variations 
111 form which have been observed are— cuneatum, with
