To this species, certainly, and probably to the variety rhœticum, 
belongs a plant “gathered on y? mountains of Mourne, in y? county 
of Down," by Sherard, and now preserved in the University Her- 
barıum, Oxford. Itis the Asplenium Adiantum-nigrum, B. of Sir J. 
E. Smith, and is referred to Asplenium acutum by Mr. Newman. Sir 
J. E. Smith correctly describes it as of a delicate membranous 
texture, the leaflets finely laciniate and without fructification. We 
are indebted to Mr. Masters for a photograph of Sherard's plant, 
which leaves no room for doubt that it is an Athyrium. It is 
assuredly not at all like Asplenium Adiantum-nigrum, or Asplenium 
acutum. The frond is about a foot long, linear-lanceolate, bipinnate, 
with narrow oblong pine, of which it would appear that the veins 
are more perfectly developed than the parenchyma, hence the appear- 
ance of being palmately laciniate. It is just such a state as might 
be expected to be produced in a dark cave, in which this is said to 
have grown. 
26. flezuosum (M.). This variety resembles rheticum in its upright 
growth, its distant ascending pinnse, and its distant narrow convex 
pinnules with ineurving lobes; but is peculiar in the very strongly 
marked flexuose character exhibited by the main rachides, and not 
unfrequently by the stipites also; they are sometimes so much 
twisted as to become perfectly grotesque. It was found at Winder- 
mere in Westmoreland by Mr. J. Huddart, and is cultivated by 
Mr. Wollaston. 
27. gracile (M.). A slender lax and very graceful dwarfish 
variety, of drooping habit. The fronds, excluding the stipites, are 
about a foot long, and six inches broad, lanceolate in outline. The
