Anatomy of the generative structures of the Subantarctic flowering plant Colobanthus apetalus (Labill.) Druce
This study investigated the details of the morphological and anatomical structure of the generative organs of the Subantarctic flowering plant, belonging to the family Caryophyllaceae - Colobanthus apetalus (Labill.) Druce. The research material was collected in hostile natural conditions in Subanta...
