GENUS INDEX
GENUS CODE: DIDYM GENUS SCIENTIFIC:Didymoglossum GENUS AUTHORITY: GENUS COMMON: Filmy Fern GENUS SUMMARY: A genus of 30-40 species, primarily tropical. All five of our species belong to subgenus Didymoglossum (Ebihara et al. 2006). GENUS IDENTIFICATION: GENUS REFERENCES: Wessels Boer (1962)=Y; Ebihara et al. (2006)=Z; Ebihara et al. (2007); Iwatsuki in Kramer & Green (1990); Morton (1968); Dubuisson et al. (2003).
FAMILY INDEX
FAMILY CODE: HYMENO FAMILY SCIENTIFIC:Hymenophyllaceae FAMILY AUTHORITY: Link 1833 FAMILY COMMON: Filmy Fern Family FAMILY SUMMARY: A family of 6-10 (or many more) genera and about 600 species. This treatment follows the generic interpretation of Ebihara et al. (2006), which splits Trichomanes (as both polyphyletic and morphologically diverse) and retains a broad and monophyletic Hymenophyllum. See Moran (1998) for an interesting discussion and overview of independent fern gametophytes in e. North America. FAMILY REFERENCE: Farrar in FNA (1993b); Ebihara et al. (2006, 2007); Iwatsuki in Kramer & Green (1990); Morton (1968). {add for FL: Trichomanes holopterum, Didymoglossum kraussii, Didymoglossum lineolatum}

SCIENTIFIC NAME: Didymoglossum petersii
COMMON NAME: Dwarf Filmy Fern
SYNONYMY: [= K3, Z; = Trichomanes petersii A. Gray - Ar, FNA, K1, RAB, S, Tn, W, WH3, Y]
PHENOLOGY: Jun-Aug.
HABITAT: On vertical faces of acidic rock outcrops in humid gorges, primarily of the Savannah River drainage, in the context of the very humid escarpment gorges on relatively dry rocks, not on rocks receiving substantial seepage or spray from waterfalls, also on outcrops of Altamaha Grit in the Coastal Plain, and on treebark in swamps (in LA and MS).
COMMENTS: W. NC, nw. SC, sw. and sc. TN, south to n. peninsular FL, c. AL, s. MS, and e. LA; disjunct in the Ozarks and Ouachitas of AR; disjunct in Mexico (Chiapas, Veracruz, and Puebla) and Guatemala. This diminutive species is often overlooked, except by bryologists and hepaticologists; superficially, it does resemble a moss or liverwort more than a fern.
