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.

HORTICULTURAL
Plant Sale Text: Dixie wood fern has a dramatic, strongly erect vase-shaped form, with each plant ultimately reaching up to 4 ft. in height while only about 2 to 3 ft. wide. Its slender semi-evergreen fronds have a beautiful dark green color. Its fronds do not produce fertile spores. This unusual southeastern native fern is a naturally occurring hybrid between Dryopteris celsa and D. ludoviciana. It grows best in soils that retain some moisture and never get too dry.
