Remarks. — Some very fine specimens have been 

 collected. Dr. Stur * unites this species with Aspidites 

 silesiaciis Goppert. f Dr. Weiss, Berlin, has favoured me 

 with specimens of this latter fern, which appears to be 

 identical with Pccopteris pluinosa Artis sp. This last- 

 mentioned species, however, appears to me to be distinct 

 from Splienopteris crenata. The Aphlebia attached to the 

 rachis of Sphenopteris crenata.^ to which Lindley and Hutton 

 gave the name of Schizopteris adnascens, are not a distinct 

 species but an integral part of the fern. Some of the 

 specimens collected by Mr. Hemingway shew this character 

 most beautifully. Somewliat similar Aphlebia occur on 

 recent ferns, as Alsopldla capensis J. Sm. 1 and Gleichenia 

 gigantea Wall. §
