2.— ASPLENIUM ALTERNIFOLIUM. 
ALTERNATE-LEAVED SPLEENWORT. 
(Plate 3, fig. 2.) 
Cha. — Frond pinnate. Pinnae alternate, wedge-shaped, notched, 
Syn. — Asplenium Alternifolium, Smith, Hook., Dicks., With., Gulp., Jacq. 
— Asplenium Gennanicum, Willd., Hoffm., Ehrh., Lam., Weis., Gray. 
— Pliyllitis heterophylla, Moench. — Scolopendrium Alternifolium, Both. 
— Asplenium Breynii, Betz. 
Fig. — E. B. 2258. — Jacq. Misc. t. 5 /. 2. — Breyn. Cent. 1 t. 98. 
Des. — Frond from one to three inches high, very light green, 
upright, delicate, about half covered with pinnae, which are alternate 
and wedge-shaped, the larger partly three-cleft, the smaller bluntly 
notched at the end only. Rachis dark at the base only. Sori 2 to 4 
on each pinna, small, light brown, becoming confluent, but not 
occupying the whole under surface. Indusium entire on the margin. 
This species is intermediate between the last and Asplenium Ruta-muraria, 
although of a more delicate snd erect habit than either ; its colour also is much 
lighter and its sori smaller and less confluent. 
The plants sold under this name in the nurseries around London are the 
true species derived from some plants brought wild from Scotland, about ten 
years ago, and given to the Countess Dc Vande at Bayswater, and from her 
garden distributed around. It quite retains its character in cultivation. 
Had. — Found originally by Mr. Dickson, on rocks in the south of Scotland, 
two miles from Kelso on the Tweed. Now existing in Perthshire, Mr. 
Bishop. Very sparingly near Dunfermline, near Edinburgh, Dr. Dewar. 
Dunkeld, Dr. Macnah. 
Geo. — Germany, Sweden, & Switzerland, where it is quite an alpine plant.

(Plate 3, fig. 3.) 
Cha. — Frond oblong, pinnate. Pinnae obtuse, serrate, slightly 
auricled above. Rachis winged. 
Syn. — A splenium marinum, Linn., Willd., Huds., Bolt., Dicks., Lightf.,

Fig.— E. B. 392.— Lob. Ic. 814. — FI. Lend. 60.— Bolt. Ib.—Ger. 1143. 
Des. — Root very thickly tufted, black, with stout fibres. Frond 
6 to 9 inches high, pinnate, irregularly oblong, obtuse. Rachis 
winged all the way down, black, shining, smooth, without pinnae at 
the lower part, above bearing about twenty on each side, mostly 
alternate, obtuse, about an inch long in the middle of the frond, 
running at the base into the wing of the rachis, therefore slightly
