SYNOPSIS. 
lieve has not been used as generic since the introduction of 
the binominal nomenclature. I consider that the name of Sco- 
lopendrium should be confined, as intended by its author, to the 
species. The genus is generally acknowledged as distinct. 
1. Ph. Scolopendrium fig. p. 289 (as Scolopendrium vulgare). 
Asplenium S. Limiens, Sp. PI. 1537. Scolopendrium vul- 
gare, Sm. Eng. FI. iv. 301. Hook. Br. FI. 443. Bab. 
Man. 389. 
Genus Amesium. Ultimate divisions without a distinct mid- 
vein. The species comprised in this genus were separated by 
Roth from the other Asplenia^ and united with my Phyllitis 
Scolopendrium under the generic name of Scolopendrium^ but 
they do not possess the singular mode of fructification observa- 
ble in that genus. 
1. Am. septentrionale, fig. p. 269 (as Asplenium septentrio- 
nale). Acrostichum s. Linneus, Sp. PI. 1524. Asplenium s. 
Brit. aut. 
t2. Am» germanicum, fig. p. 265 (as Asplenium germanicum). 
Asplenium g. Weiss, Plantae CryptogamicaB, p. 299, date

Miscellany, ii. 51, date 1781. Sm. Eng. FI. iv. 296. Hook. 
Br. FI. 442. Bab. Man. 389. 
3. Am. Ruta-muraria, fig. p. 261 (as Asplenium Ruta-muraria). 
Aspl. R.-m. Linn. Sp. PI. 1541, and Brit. aut. 
Genius Asplenium, Linneus. Ultimate divisions generally dis- 
tinct and leaf-like, each with a distinct midvein ; lateral veins 
alternate branched ; clusters of capsules on anterior branch, 
their direction towards apex of division; involucre flat its at- 
tachment straight, its opening towards the apex of division. 
* Fronds simply pinnate.
