Achillea pratensis (Asteraceae) - a recently recognized species of the Czech flora

Popis výsledku v původním jazyce

Milfoils (Achillea millefolium agg.) of the Czech Republic were studied in the field as well as in most of the Czech herbaria. Achillea pratensis Saukel et Länger, recently described from Austria, was found to be common in the Czech Republic. Its occurrence was confirmed by chromosome counts (2n = 36) in 74 plants from 26 localities, and more than 240 herbarium specimens of this species were revised. Using canonical discriminant analysis, seasonal variation of A. pratensis was analysed. The first generation (spring) and second generation (summer) shoots proved to be morphologically different (they can be separated mainly by number of nodes, plant height, leaf width, and bract length). Thus, the description of the species provided by Saukel et Länger had to be modified to include spring shoots. Morphological and taxonomic delimitations from other tetraploids (A. collina Rchb.) have not yet been satisfactorily defined. Also, taxonomic relationships to A. tenuis Schur described from Trans
