Var. ft. OBTUSUM (Willd.). 
Plate 46. Fig. 2. b Pinnule. 
Generally a stronger growing form than the type, rather 
more cut, with narrow, spathulate, and lobed pinnules, and 
with three to five sharp, but not divergent, equal teeth on 
each lobe. This form approaches A. solidum Kze, which 
may also be a more altered form of A. adiantum-nigruni , as 
another further grade appears in A. acutum Bory. 
In the fine series of European specimens of this group in 
Herb. Gub., the more rounded form appears as A. adiantum- 
nigrum L., and our var. obtusum as A. serpentini Tausch, but 
A. solidum is not represented. 
Schlechtendal gives two forms of A. adiantum-nigrum, the 
one representing our type, and the other is described as being 
A. acutum Bory, but the figures are both of the type, and 
almost alike except in size.

This variety occurs where the species is growing vigorously, 
or among grass, but its separate distribution has not been 
noted, and its localities are included above with those of the 
type.
