onr plant. It must be either this, or Aspldinm alpinwm, 
Willd. ii. 139., which is likewise a Cystea, figured in Jac. Ic. 
Ear. t. 642, and in Segu. Veron. Suppl. t. I./. 3. But neither 
the plant itself, not either of these representations, suits 
the wooden cut of Bauhin, which agrees far better with 
(7. regia, particularly in the shape of the leaflets. Haller, 
very unsuitably I think, refers it to Pteris crispa; which 
circumstance, and the singular jumble of synonyms under 
his n. 1707, Cystea frayilis, induces a suspicion that he had 
not accurately observed these alpine ferns, and especially 
that he had never seen Vaillant's Filicula regiu at all." 
On the culture of this, and other species of the genus, 
we have been obliged with the following notes from Mr. 
W. Btjevb, who has very successfully cultivated Ferns :-- 
" I have had several species of Cystopteris in my 
possession, but have not had all the species, but such 
as I have tried, I have always found to prefer and 
thrive best in well-drained situations. The only in- 
stance that I have of their cultivation, out-of-doors, was 
upon some rockwork which I formed at the north end 
of our conservatory, where there was a piece of brick- 
work (which did not look very sightly) about two-aud-a- 
half or three feet high, and I formed this rockwork to 
hide it, but you may imagine that the more elevated 
part of it must have been very much drained, when I 
had only about eighteen inches for the base. It was 
upon this piece of work that I placed (among other 
small, young Ferns) a plant of each of the Cystopteris 
that I had in my possession. They were three in 
number, Fragilis, Dickieana, and Alpina. 
" For cultivation in pots, I used, for compost, two parts
