Perhaps best known as the Phymatodes longifolia. A charming Fern, remarkably distinct from all others. Thesubmarginal line of sori, and the raised oval-shaped umbonesshewing the place of the sori when viewing the frond fromthe upper surface, render it an exceedingly desirable speciesto all lovers of the curious and beautiful in this tribe of plants. For fronds I am indebted to Mr. J. Smith, Curator of theRoyal Gardens, Kew; and to Messrs. Booth, of Hamburg. This species may be procured of Messrs. Booth, of Hamburg. The illustration is from Mr. Smiths POLYPODIUM 2.
