LASTREA FILIX-MAS. 



Fiff. 210. 



Erosa-dentigera, Stansfield, MS. (Fig. 210.) — Length 

 twenty inclies, breadth six to seven inches. Pinnte distant on 

 the lower half, and approximate on the upper half; opposite 

 or subopposite on the lower half and alternate above, ascending. 

 Pinnules opposite or subopposite, their apices blunt or rounded, 

 dentate and erose. Colour rich screen. 



Pig, 211.— Middle piniiaj. 



Recurva, Moore. (Fig. 211.) — A variety of Lastrea 

 pseudo-mas. First discovered near Doncastcr, in 1857, by 

 Mr. S. Appleby; and again in Westmoreland, in 1859, by 

 Messrs. Stansfield, of Todmorden. Length of frond eighteen 

 inches. The pinnae and pinnules recurved, the pinnnles being 

 crisped upwards. Sori confined to the upper portion of the 

 frond, where very copious, and eventually confluent. This 

 variety bears a striking resemblance to Lastrea recurva, and 

 indeed might be mistaken for that species by those not well 

 acquainted with Ferns. The illustration is from Messrs. 

 Stansfield's fronds.
