Extract

Nephrolepis has generally been placed by systematists among the Davallioid ferns. The latter, which have always presented difficulties to the systematists, are divided by Professor Bower (Filicales, vol. iii, chap, xxxvii) into three groups, Nephrolepis being placed in the first of these along with Humata and Davallia. This threefold division of the Davallioid ferns was based mainly on soral characters, and the absence of critical data with regard to such characters in the genus Nephrolepis led to the present investigation.
