Specimina a nobis et aliis in Hungaria lecta omnino cum illis

que cl. Kaulfusz in Teneriffa lecta amice communicavit. Inveni-

b. Extracts from authors who have treated this fern as possibly or 
certainly a variety of Adiantum nigrum :— 
1. DILLENIUs. 
(In hac planta seminalia nulla observare contigit, unde an species 
vere distincta sit, dubium videtur. Forsitan non nisi varietas est, 
Adianti nigri officinarum J. B. loci umbrositati originem debens, nam 
in spelunca, quam radii solares nunquam illustrabant, nascebatur. 
Sane vero si varietas sit, singularis ea est et valde speciosa).—Dille- 
nius in Ray, Synopsis, 3rd edit. p. 127, date 1724. 
2. Sin J. E. Smita. 
Asplenium Adiantum nigrum (. 
Sherard’s original specimen of the variety 8, preserved in his her- 
barium at Oxford, is truly elegant, of a delicate membranous texture, 
the leaflets palmate finely lacimiated. Plukenet’s figure by no means 
does it justice. No fructification is discernable——Smith, Eng. FI. 
iv. 311, date 1828.
