* I am aware that Mr. Moore considers Mr. J. Smith’s Stenosemia aurita (noStenosemia, certainly) to be the plant Presl had in view for his Digrammariaambigua; for he says, “ there can be no doubt, from Presl's figure and descrip-tion, that this is the plant he intended to call Digrammaria , but all his synonymsare erroneous.” But Presl was surely too acute a pteridologist to commit suchan error, and to give two figures with strongly serrated margins (as in theplant before us) to the lobes, while those of J. Smith’s Stenosemia are quiteentire. Indeed, as far as I know, this plant is exclusively a discovery of Mr.Cuming; and, as such, Presl describes it most accurately in his * EpimeliaBotanica' (quoted by Mr. Moore), under the name of Heterogonium aspidioides.That Presl’s Digrammaria is generically identical with Asplenium (or Anisogonium)decussatum, there cannot be the smallest question.
