Taxonomic notes on the New Zealand flora: the status of Schizaea australis and S. fistulosa, and lectotypes in Lygodiaceae and Schizaeaceae

Figures & data

Figure 1  Twelve different specimens of the S. australis/fistulosa aggregate collected between Rabbit Gully and Appos Flat, Rockville, Nelson, by Ian Lash, 12 May 1964 (CHR 343596). Three of the specimens are included in this morphological analysis (fourth from the left, S. australis; fifth from the right, putative hybrid; third from right, S. fistulosa).
