mis, stipite perbrevi rachideque inferiore subtus paleaceis.

This is undoubtedly a true Asplenium : and if the underside 
were covered with scales as in the Grammitis Ceterach of our 
European rocks and walls, it would be scarcely possible to dis- 
tinguish it from that plant. It will be recollected too, with 
regard to G. Ceterach, that Mr. Wilson finds “ evident traces 
of an involucre, a narrow membrane on the lower side of the 
sorus :” so that I think that well-known plant must be referred 
to Asplenium and placed next our present one. And they are, 
if lam not mistaken, the only species of the extensive genus 
Asplenium which have truly pinnatifid fronds. 
In the species here figured, besides the sori upon the segments 
of the frond, opening towards the central nerve, there is a chain 
or series parallel with the main rachis, and opening towards it, 
thus turning their backs, as it were, to those situated on the 
segment.
