Recognition of the tetraploid Polypodium calirhiza (Polypodiaceae), in western North America
Taxonomic study of the Polypodium californicum/glycyrrhiza complex in California reveals four taxa: a tetraploid, a triploid, and two diploids, P. californicum and P. glycyrrhiza. The tetraploid, here named Polypodium calirhiza, mimics some forms of P. californicum in southern California but is read...

description | Taxonomic study of the Polypodium californicum/glycyrrhiza complex in California reveals four taxa: a tetraploid, a triploid, and two diploids, P. californicum and P. glycyrrhiza. The tetraploid, here named Polypodium calirhiza, mimics some forms of P. californicum in southern California but is readily distinct in northern and central parts of the state. It is probably of allopolyploid origin involving the two diploids, as judged by its morphological intermediacy and chromosome pairing in triploid hybrids with P. glycyrrhiza. A principal components analysis also demonstrates this intermediacy. Polypodium calirhiza shows a wider tolerance for different habitats and greater range than either of its putative parents. El estudio taxónomico del complejo Polypodium californicum/glycyrrhiza en California revela cuatro taxa: un tetraploide, un triploide, y dos diploides, P. californicum y P. glycyrrhiza. El tetraploide, aquí nombrado Polypodium calirhiza, mimetiza algunas formas de P. californicum en el sur de California pero es fácilmente distinguible de los areas de norte y centro del estado. Probablemente esta nueva especie sea de origen alopoliploide implicando los dos diploides a juzgar por su forma intermedia morfológicomente y su sinapsis cromósomico en híbridos triploides con P. glycyrrhiza. Un análisis de los componentes principales tambien demuestra esta naturaleza intermedia. Polypodium calirhiza demuestra una mejor tolerancia a mas diversos habitates y una area de distribution mas amplia que cualquiera de sus dos teoricos progenitores. |
