2. Polypodium virginianum L. (common polypody) Pl. 15f,g; Map 55

P. vulgare L. var. virginianum (L.) A.A. Eaton

Rhizome scales orangish brown, concolorous or with a somewhat darker central stripe, lanceolate, the margins slightly toothed. Leaves 4–40 cm long, the petioles green to light brown, grooved on the upper surface, glabrous. Leaf blades herbaceous to somewhat leathery, lanceolate, tapering to the tip, the lobes with rounded to somewhat pointed tips and entire to slightly toothed margins, glabrous. Sporangia intermingled in the sorus with long, club-shaped, glandular hairs, with 64 spores. 2n=148. June–August.

Most common in the eastern portion of the Ozark Division, locally west to Laclede County and north to Marion County (eastern U.S. and Canada). Ledges and crevices of bluffs and boulders, on sandstone, chert, granite, and other acidic substrates.

The relationships among the American and European species of the P. vulgare complex were first elucidated by Shivas (1961). True diploid P. vulgare occurs in Europe. More recently, Haufler and his associates (Haufler and Windham, 1991; Haufler and Wang, 1991) have shown that P. virginianum is a fertile, tetraploid derivative of past hybridization between two closely related diploid species, P. appalachianum Haufler & Windham and P. sibiricum Sipliv., neither of whose ranges extends to Missouri.
