GENUS INDEX
GENUS CODE: DRYOP GENUS SCIENTIFIC:Dryopteris GENUS AUTHORITY: Adans. GENUS COMMON: Woodfern GENUS SUMMARY: A genus of about 400 species, nearly cosmopolitan, but concentrated in temperate Asia. Sessa, Zimmer, & Givnish (2012) discuss the phylogeny and biogeography of Dryopteris; the clades shown in the key are from their work. GENUS IDENTIFICATION: Identification notes: Dryopteris and Athyrium are often confused when not fertile; they can be easily distinguished by breaking off a leaf and counting vascular bundles (which will appear as thread-like strands). Dryopteris has 5 and Athyrium has 2. Many Dryopteris species will hybridize with one another to form sterile hybrids. Whenever two or more Dryopteris species are found growing together, there is a good chance that hybrids are present. Hybrids generally show intermediacy between the two parents, and have abortive sporangia or spores.

FAMILY INDEX
FAMILY CODE: DRYOPT FAMILY SCIENTIFIC:Dryopteridaceae FAMILY AUTHORITY: Ching 1965 FAMILY COMMON: Wood-fern Family FAMILY SUMMARY: A family of about 40-45 genera and 1700 species, cosmopolitan in distribution, but concentrated in temperate and montane areas. Here circumscribed (following Smith et al. 2006) to exclude Onocleaceae and Woodsiaceae. FAMILY REFERENCE: Smith in FNA (1993b); Smith et al.

Plant Sale Text: Log fern, found in swamps and calcareous floodplains of the Eastern U.S., produces large, upright fronds whose dark green color and elegant shape add a beautiful lushness to shady parts of a home landscape. A naturally occurring, fertile hybrid between D. goldiana and D. ludoviciana, log fern is semi-evergreen. It is often found growing on rotting logs (hence its common name).

PHENOLOGY: Jun-Sep.
HABITAT: Swamps, seepage bogs, and calcareous floodplains, typically associated with calcareous substrates.
COMMENTS: Ne. NJ and ne. NY west to s. IL, e. MO, and AR, south to SC, GA, n. AL, TN, e. and n. LA, and e. TX (Mink, Singhurst, & Holmes 2011a); disjunct in w. NY and w. MI; overall very scattered in its distribution.
