| Description | Flow cytometry measurements confirmed the occurrence of Polypodium x mantoniae (P. interjectum x P. vulgare) in the Cheile Turzii Nature Reserve (Apuseni Mts., Cluj County). The relative 2C DNA content of this pentaploid hybrid was detected in relation to that of tetraploid Polypodium vulgare and hexaploid P. interjectum. Polypodium interjectum was found in the Bigăr Nature Reserve (Semenic Mts., Caraş-Severin County), close to its known locality in Cheile Nerei. Anatomical and morphological features (number of thick-walled cells in the annulus, spore length and stoma length) of all three Romanian Polypodium taxa are discussed and a brief survey of the distribution of these taxa in other European countries is included |
