		- Vittariaceae The Pteridales are ferns that have their sori in linear strips under the edge of the leaf tissue, usually with the edge of the lamina reflexed over.
		Ceratopteris is also important in the study of pteridophytes because it is a commonly used model organism for use in genomic studies, due to the ease and rapidity with which it can be grown in laboratories.
		Relationships among these groups remain unclear, and although some recent genetic analyses of the Pteridales suggest that neither the family Pteridaceae nor the major groups within it are all monophyletic, as yet these analyses are insufficiently comprehensive and robust to provide good support for a revision of the order at the family level.

		Turnau, K; Anielska, T; Jurkiewicz, A. Mycothallic/mycorrhizal symbiosis of chlorophyllous gametophytes and sporophytes of a fern, Pellaea viridis (Forsk.) Prantl (Pellaeaceae, Pteridales).
		The presence of AM fungi in both gametophytes and sporophytes of P. viridis resulted in the development of larger leaf area and root length of the sporophyte.
		The analysis of gametophytes from the Botanical Garden in Krakow (Poland) showed that cordate gametophytes of Pteridales, namely Pellaea viridis (Pellaeaceae), Adiantum raddianum and A. formosum (Adiantaceae), were also mycothallic.

		Lindseales, Dennstaedtiales and Aspleniales were apparently derived from polyploidy of n=12, while Hypolepidales were probably derived from n=13.
		Pteridales may have developed from n=14, but this is much less clear.
		I propose that the subsequent orders, from Athyriales through Polypodiales, developed from a basal count of n=14 tripling through hexaploidy to n=42, then reducing to n=41, n=40, n=37, and so forth.
