LASTREA FILIX-MAS. 



277 



Inciso-kecurva, J/oorc— Found in 1857, by Mr. S. Appleby, 

 near Doncaster. A sub-variety, with pinnse and pinnules 

 recurved, which distinguishes it from its otherwise near allies 

 incisa and deorso-lobata. 



Fig. 227.— Frond. 



Lacerato-cristata, Monkman. (Fig. 227.) — This oddity is 



a sport from spores of the variety cristata, raised by Mr. C. 



Monkman, of Malton, who is of opinion that the variety will 



remain permanently dwarf, and it is promising to be constant. 



The parentage is unmistakeable, but the pinnae are variously 



shortened and wanting, and in place of pinnulets are deeply 



incised into irregularly lobed divisions, which shew some 



tendency to crest. The pinnae and the fronds are sometimes 



crested, but not always distinctly so, and occasionally not at 



all. So far there has been no indication of fertility. Fronds 



six to eight inches in length. The illustration is from Mr. 



Monkman's plant — the only one known.
