Under our description of Zymenophyllum hirsutum we have stated it as our opinion, that authors 
were scarcely justified in referring Plumier's Zi digitata, (FW. t. 50. B.) to that species, which has 
simply pinnate or rather pinnatifid fronds; and that it is altogether a much smaller species: nor 
were we then acquainted with any Zymenophyllum with which it could with propriety be considered 
identical. Since that period, however, among a valuable collection of Ferns received from Professor 
William Jameson of Quito, we find a species so well according with the fizure of Plumier, that we 
have scarcely a doubt as to the propriety of quoting it as a synonym. It is a robust and handsome 
plant, with, comparatively, broad primary segments of the frond, which are less deeply divided than 
most of our bipinnatifid species. "The fructifications are numerous, and terminate many of the 
laciniz, so as to form a sort of interrupted line or margin round the principal segments.
