Stipes generally shorter than the frond, purple through- 
out; frond pinnate ; pinnae distant, stalked, ovate; clusters

Asplenium viride. 
1753. Asplenium Tricliomanes ramosum, Linn. Sp. PI. 
1541; With. Bot. Arr. Veg. 654. 
1762. Asplenium viridi, Huds. FI. Ang. 385. 
1777. Asplenium viride, Light/. FI. Sc. 663 ; Finds. FI. Ang. 
453 ; Bolt. Fil. Brit. 24, t. 14 ; With. Arr. 768 ; Sm. E. 
F. iv. 306, E. B. 2257 ; Mack. FI. IFih. 341 ; Newm. 
N. A. 28, F. 281; Hook, and Am. 573; Bab. 414. 
Stipes somewhat shorter than the frond, purple at the 
base, otherwise green ; frond very narrow, linear, pinnate ; 
pinnae stalked, distant, diamond-shaped, toothed ; clusters 
of capsules linear, at last confluent, rust-coloured. 
On rocks in mountain districts only. 
Obs . — In this instance the earliest name, Asplenium Tricliomanes 
ramosum, is abandoned, because evidently given as that of a variety, 
not of a species. The second in date is also abandoned, because of its un- 
grammatical termination, subsequently corrected by the author himself.
