CyclopeUis was first described by me as a genus in the Botanical Magazine for 1846. In 1852, 
M. Fee characterized the above species under the name of HemicardioJi Nephrolepis, and quoted Cych- 
peltis as a synonym, thus changing both the generic and specific name, and this he does without assigning 
any reason, it being another of the many instances in M. Fee's ' Genera Filicmn ' of names being changed 
and transposed without just cause, a practice serving only to create confusion.
