ASPLENIUM ADIANTUM-NIGRUM. 77 



Mr. Moore, in his "Nature-printed Ferns," describes nine 

 varieties, viz.: — 



1st. — Ohtusuju, Willdenow. Found in Ireland. 



2nd. — Ohlongum, Moore. From Guernsey. 



3rd. — Variegatum, Wollaston. 



4th. — Midtifidum, Wollaston. 



5th. — Fissum, Moore. 



6th. — Intermedium, Moore. 



7th. — Oxyphyllum, Moore. 



8th. — Decompositiim, Moore. 



9th. — Aciitum, Bory. Ireland, Madeira, etc. 



Grows on rocks, and is very generally distributed throughout 

 Great Britain, j^^owhere have I seen it more luxuriant than 

 on the sandstone rocks in the Nottingham Park. 



It can be procured from any Nurseryman, if not to be 

 obtained in the immediate neighbourhood of the cultivator. 



My thanks are due to Mr. Sim, of Foot's Cray, for plants 

 of the varieties acutum and ohtusum. 



The illustration is from a plant in my own collection.
