This Fern exhibits upon the same frond, and even upon the same universal pinna, the fructifica- 
tion both of Cenopteris and zdsplenium ; and the nature of this is well explained by the learned 
Brown: *Canopteris ab z4splenio differt tantummodo pinnulis profunde incisis, lobis unifloris 
angustis, involucris inde marginem attingentibus et extus respectu lobi, intus vero quoad costam e 
qua vena fructifera ortum ducit, liberis: species quoque dantur frondibus partim Z4splenio partim 
Canopteridi respondentibus, et etiam in uno et eodemque Eu characterem utriusque generis 
exhibentibus." Prodr. p. 150.
