Fée’s name for this fern is the oldest, and is the one used 
by Hooker in Speczes Filicum, and Mr. Baker in Synopsis Fil- 
icum, and if the species is to be maintained should be the one 
used. 
Tam, however, averse to having my own name attached to 
it under Aspidium, and the more particularly so as I look 
upon it asa mere form of A. patulum Swz. (N. Mexicanum 
Hk.),a species which, the more I see of it, I am convinced is 
a variable and prolific of forms as our own A. spinulosum.

A. parallelogrammum Kze. 
§965, ravines, Sierra de San Felipe, Dec. 12, 1895. 
Fournier keeps this distinct as a species, but the large series 
of specimens that I have examined incline me to accept 
Hooker's disposition of it. It is, however, certainly distinct 
‘tough from ordinary fi/ix-mas to make a very good variety.
