Martínez, O. G. (2011). Morphology and distribution of the complex Pteris cretica L. (Pteridaceace) for the American continent. Candollea 66: 159–180. In Spanish, English and French abstracts.
The Pteris cretica L. (Pteridaceae) taxonomical complex is revised for the American continent. It is composed by seven species: Pteris ciliaris D. C. Eaton, Pteris cretica L., Pteris denticulata Sw., Pteris ensiformis Burm. f., Pteris multifida Poir., Pteris mutilata L. and Pteris tristicula Raddi. Morphological characters have been identified in order to distinguish the members of the group. An identification key is proposed and a diagnostic description, distribution and illustrations are provided for each species.
