A fossil Vallisneria plant (Hydrocharitaceae) from the Early Miocene freshwater deposits of the Most Basin (North Bohemia)
2009
Abstract
A new fossil species of Vallisneria (V. janecekii Bogner & Kvacek, sp. n., Hydrocharitaceae) is reported from Early Miocene freshwater lake deposits of the North Bohemian brown coal basin (Czech Republic). It is based on a single fragmentary sterile plant bearing two clusters of ribbon-shaped widely serrulate leaves on a short rhizome.
It is a potential producer of seeds described from equivalent and slightly older deposits in Saxony (Germany) as Vallisneria ovalis Mai.
