OUR FRONTISPIECE. 



The Lastreas (Nephrodiums). 



It will be seen by our frontispiece that the genus to 

 which our common Male Fern [Lastvea filix mas) belongs 

 has proved itself very capable of rivalling even the versatile 

 and multiform species of the Polystichums, and Lady 

 Ferns by the production of beautiful and symmetrical 

 " sports." 



The varieties depicted, in the order of their species, are as 

 follows : — 

 Fig. I. Lastrea dilatata grandiceps Barnes.

15. ,, ,, folioso-cristata (top half of frond).

* This very fine form turned out to be inconstant, and we doubt 

 very much if it still exists ; we have, however, inserted it to show 

 capabilities. It was found in North Devon,
