Pellaea glabella Mett. ex Kuhn ssp. simplex (Butters) A. Löve & D. Löve[FNA2, HC2]
simple cliffbrake

Publication: Taxon. 26: 325. 1977.

Origin: Native

selected vouchers: WTU

Notes: FNA2: "This western counterpart of Pellaea glabella subsp. glabella is an apogamous tetraploid. A. F. Tryon (1957) and D. B. Lellinger (1985) hypothesized that it might have arisen as a hybrid between the western diploid member of the P . glabella complex (here called subsp. occidentalis ) and P . atropurpurea . G. J. Gastony (1988) has shown conclusively, however, that P . glabella subsp. simplex is an autopolyploid derivative of subsp. occidentalis and does not contain genes contributed by P . atropurpurea."
