A CONSrUERATlON OB' CERTAIN GENERA 207 



Ophrys ovata L, the type of Ophrys, and the name Cardiophyllum 

 takes its place with Listera as a synonym of Ophrys. 



78. — AetopTeron Bhrh., 1. c. 

 The type is designated as Polypodium aculeatum L. This is the 

 type of Polystichum Roth, and antedates the publication of that 

 fern genus by several years. The species of the United States which 

 should be considered under this name number about eight. A 

 contemporary paper in which these species are transferred to 

 Aetopteron, has been submitted for publication to the American 

 Fern Journal. 



86. — Cornilla Ehrh., 1. c. 

 This is but a slight change in spelling of Coronilla L., and the 

 type species, Coronilla coronata h-, is also here designated as the 

 type of Cornilla Ehrh.
