10. Horned Irregular Lady Fern. Cornuto-irregulare, 
TV*. In addition to the abnormal appearance of the 
irregular Lady Fern, this variety has a little horn projecting 
at the apex of the frond and of some of the pinnae, which 
gives it a curious disfigured aspect. M. Axminster. 
11. Eroded Lady Fern. Erosum. W. This plant is of 
the ordinary size of the species and for the most part 
regular in its frond and pinnae. The regular leafiets are 
blunt, oblong, pinnatifid, having the lobes unequal, with 
short blunt teeth : those which are irregular are very 
unequal in size and have a torn, shattered appearance. 
They are also occasionally forked or even multifid. M. 
Hawkchurch. 
12. Thrice-cleft Lady Fern. Trijidum. M. This is a 
slender and neat variety, with a frond about eighteen inches 
high. The pinnae are narrow lance-shaped. The leafiets 
are egg-shaped, having three teeth at their apex, and hence 
the name. M. Hawkchurch. 
13. Misshapen Lady Fern. Informe. M. ‘‘A very 
“ curious pigmy variety never exceeding three inches in 
“ height or an inch in width. The fronds are generally very 
irregular in outline ; some forked in the rachis, others in 
“ the stipes (stalk) and then twin-fronded, others again are 
“ nearly plain and more regular. The pinnae vary much in 
“ shape, sometimes nearly round with serrated edge, some 
‘‘ forked, others much lengthened, here and there one is 
altogether missing, in other places three or four in 
“ succession on one side of the frond are wanting. The 
“ pinnules vary in shape as much as the pinnae, consisting 
often of a mere tooth or twin teeth. In some places the 
“ irregularities convey the impression that the pinnae and 
‘‘ pinnules had confusedly run together.’* M. Hawkchurch :
