In dry shady hedge bottoms, and about the roots and mossy trunks 

 of old trees, as well as on rocks and old walls, common. 



/3. In a dark cave among the mountains of Mourne, County of 

 Down, Ireland. Sherard. 



Perennial. June — October. 



Much larger than the foregoing. Root tufted, fronds several, 

 about a foot high ; their stalks scaly at the base ; the leafy 

 part smooth, deltoid ; taper-pointed, as are all the primary di- 

 visions ; smooth, firm,' erect, doubly, or when perfect triply, 

 pinnate, in an alternate order. Leajieis lanceolate, tapering at 

 the base and somewhat stalked, deeply and sharply serrated, 

 or notched, in the upper part ; their colour a darkish shining 

 green 3 the stalk purplish brown, polished. Masses oblong, 

 numerous, ranged alternately in close central rows, with white, 

 entire, conspicuous covers. Capsules chesnut-coloured. 



Sherard's original specimen of the variety /3, preserved in his 

 herbarium at Oxford, is truly elegant, of a delicate membranous 

 texture, the leaflets palmate,' finely laciniated. Plukenefs figure 

 by no means does it justice. No fructification is discernible. 



Sibbald, in his Scotia Illustrata, sect. 2. 7. t. 4./. 1, describes what 

 he terms a larger kind of this common Adiantum nigrum ; but 

 by the figure no difference is discernible. 



8. A. lanceolatum. Green Lanceolate Spleenvvort. 



Frond lanceolate, doubly jMnnate ; leaflets and segments 

 obovate, deeply and sharply toothed. Principal midrib 

 not bordered.
