GENUS INDEX
GENUS CODE: POLYPGENUS SCIENTIFIC: Polypodium
GENUS AUTHORITY: L.
GENUS COMMON: Polypody
GENUS SUMMARY: A genus of about 100 species, cosmopolitan.
GENUS IDENTIFICATION: Identification notes: The two species are somewhat cryptic, and the relatively frequent triploid backcross makes field identification still more problematic. Individuals not identified to species may be referred to as Polypodium virginianum complex.

SCIENTIFIC NAME: Polypodium virginianumCOMMON NAME: Common Rockcap Fern
SYNONYMY: [= Ar, FNA, Il, K, Pa, Tn, Va, Z; < P. virginianum - C, F, RAB, S, W, WV; < P. vulgare Linnaeus var. virginianum (Linnaeus) Eaton - G]
PHENOLOGY: Jun-Oct.
HABITAT: Moist rocks.
COMMENTS: Haufler and Windham (1991) indicate that the tetraploid cytotype (P. virginianum) of the P. virginianum complex is an allotetraploid derivative of the sterile hybrid of the diploid occurring in our area (P. appalachianum) and another diploid with a boreal distribution (P. sibiricum Siplivinsky). Electrophoretic evidence supports this finding (Bryan & Soltis 1987, Haufler, Windham, & Rabe 1995). Thus, Polypodium in our area is another classic example of the reticulate evolution of pteridophytes, and the cytotypes must be treated as species and given names. Unfortunately, the two species are somewhat cryptic, and the relatively frequent triploid backcross makes field identification still more problematic. Individuals not identified to species may be referred to as Polypodium virginianum complex. The chromosome complement of P. virginianum can be symbolized as AASS.
