PolypodLaceae (Fig. 4)
With all local genera except Pyrrosia examined, this family shows extreme consistency with n = 37 in all cases. Cytologically there is nothing to distinguish Holttum's Grammitidaceae (Grammitis and Ctenopteris) from Microsorium and Anarthropteris.

The New Zealand species assigned to Microsorium by Copeland are distinct cytologically from both Microsorium (n = 36) and Phymatodes (n = 36) of Holttum as recorded by Manton (1954) and Manton and Sledge (1954). It is intended also to examine this group in greater detail.
