We investigated the population genetic structure of the invasive plant Hieracium aurantiacum (Asteraceae), a facultative apomict. We generated amplified fragment length polymorphism fingerprints for H. aurantiacum samples from across its invasive ran

Summary When pollen from Hieracium floribundum Wimmer and Grab. (Compositae) was applied to stigmas of Diervilla lonicera Mill. (Caprifoliaceae) in mixtures with Diervilla pollen, Diervilla fecundity was strongly depressed. While this phenomenon is u

Fertilizer (336 kg ha−1 year−1 NPK) was applied to an abandoned pasture in southern Ontario to investigate the impact of changing soil fertility on the process of patch formation by hawkweeds (mainly Hieracium floribundum Wimm. and Grab.: Composi

The contribution of yellow devil hawkweed (H. floribundum) to the total standing crop of an abandoned pasture in southern Ontario increased from approximately 8% to 70% as H. floribundum colonized the pasture by forming patches containing as many as

In the crowded parts of patches of Hieracium floribundum Wimm. and Grab., which were established for at least a decade in an ungrazed pasture, 7–10% of the population (3700 individuals/m2) flowered. Of the plants that flowered, 94% were alive a yea

The primary phloem system in the rhizome of Hieracium floribundum has transfer cells that have developed from companion cells and parenchyma cells, which are adjacent to sieve elements. In both cell types changes occur in the cytoplasmic organelles a

Xylem transfer cells in the rhizome of Hieracium floribundum are described for the first time and several methods used in visualizing these cells are discussed. The most marked wall ingrowths occur in transfer cells associated with the xylem of folia
