1. hieracium

   Hieracium is a large genus of flowering plants in the daisy family Asteraceae, commonly known as hawkweeds. They are perennial plants known for their yellow, white, or red flowers and their ability to propagate through seeds and vegetatively. They are typically native of temperate regions in the Northern Hemisphere. The genus is noted for its difficult taxonomy due to high frequency of hybridization and apomixis (asexual reproduction).

1. Hieracium

   Hieracium, known by the common name hawkweed and classically as hierakion, is a genus of the sunflower family Asteraceae, and closely related to dandelion, chicory, prickly lettuce and sow thistle, which are part of the tribe Cichorieae. Hawkweeds, with their 10,000+ recorded species and subspecies, do their part to make Asteraceae the second largest family of flowers. Some botanists group all these species or subspecies into approximately 800 accepted species, while others prefer to accept several thousand species. Since most hawkweeds reproduce exclusively asexually by means of seeds that are genetically identical to their mother plant, clones or populations that consist of genetically identical plants are formed and some botanists prefer to accept these clones as good species whereas others try to group them into a few hundred more broadly defined species. What is here treated as the single genus Hieracium is now treated by most European experts as two different genera, Hieracium and Pilosella, with species such as Hieracium pilosella, Hieracium floribundum and Hieracium aurantiacum referred to the latter genus. Many members of the genus Pilosella reproduce both by stolons and by seeds, whereas true Hieracium species reproduce only by seeds. In Pilosella, many individual plants are capable of forming both normal sexual and asexual seeds, whereas individual plants of Hieracium only produce one kind of seeds. Another difference is that all species of Pilosella have leaves with smooth margins whereas most species of Hieracium have distinctly dentate to deeply cut or divided leaves.
