ASPIDIUM FILIX-MAS, Vau. Cristatum-angustatum. 



PLATE LV. — A. 



Lastrea fiUx-mas, var. cristata-angustata, Mooee. 



Aspidium — Shield Fern. FiUx-mas — Male Fern. 



Cristatum-angustatum — Narrow-crested. 



In the Section Lastrea of Authors. 



The present variety is exceedingly distinct from the beautiful 

 multifid variety, cristatum. The frond is remarkably narrow, 

 nearly linear, being only from an inch to an inch and a half 

 in width. The pinnse are crested, except the upper portion 

 of the frond, and the extreme point is tasseled. 



The stem is covered with reddish brown scales. 



Length of frond twelve to eighteen inches. 



This variety was raised from spores by Mr. E,. Sim, of Toot's 

 Cray, and is quite constant. 



My thanks are due to Mr. Cooling, Nurseryman, Mile Ash, 



Derby, for the frond figured.
