imbricated variety in being horizontal in its growth and 
occasionally forked at its tip. M. Hawkchurch. 
76. Irregularly Diminished A. D. Dispar. The leading 
characteristic of this variety is that its pinnae are here and 
there irregularly diminished, all tapering to a spiny point.

77. Branched Irregularly Diminished A. D. BamO’dispar. 
This differs from the preceding in being branched at the tip 
of the fronds, either simply or three or four times. 
78. Moly’s Varying A. E. Varians MolyL Here we 
have a plant which may be truly called varying, as pinnae, 
leaflets, and fronds, all vary in size, length, and form, and 
the leaflets and pinnae are occasionally missing. The leaflets 
are crowded together and distinctly stalked. The apices 
of the fronds are simply or three or four times forked. 
This is about six inches high. M. 
79. Sharply-divided A. E. Acuto-dissectum. An acute 
fronded Eern, much dissected, two feet long, and six inches 
wide. Stalk short and stout. Mid-stalk scaly on lower 
half; reddish above. Under leaflets in lower part of the 
frond longer than the upper one. All the leaflets are 
narrow and acute with an acute auricle. M. Catherstone, 
near Charmouth. 
80. Small-pinnuled A. E. Darvi-pinnulum, This plant 
is nearly regular. Its only irregularity consists in having 
its leaflets near the mid-stalk much smaller than those in 
the upper parts of each pinna, whereas the general rule is 
quite the reverse. M. Uplyme. 
81. Ean-formed A. E. Flahellulo-forme, This is remark- 
able for having its fronds narrow one-third of its length and 
thus expanding itself in the form of a fan ; hence the name. 
It is a small plant six inches high and of a dark green 
colour. M. Offwell. 
82. Bristly Square A. E. Setoso-quadratum. Here we 
have an elegant plant, a foot high, with square leaflets 
conspicuously toothed, marginate, and having each tooth 
terminating with a long bristle. M. Colyton. 
83. Crested Little Beauty A. E. Dulchello-cristatum. 
This has all the characters of 'No, 22, and in addition it may 
be stated that at the apex of each pinna, and the frond itself,
