The fruit ultrastructure of the species from sections Praealtina (Gremli) Schljak. and Echinina (Näeg. et Peter) Schljak of the genus Pilosella Vaill. in Crimean flora
Abstract
At the first time the ultrastructure of achenes at sections Echinina and Praealtina of the genus Pilosella of Crimean flora is investigated. Common and demarcation features for studied species, as well as specific features for each section are found.
