Species
The classification of Hieracium into species is notoriously difficult. One reason is the apomictic reproduction (in which plants asexually produce seeds), which tends to produce a lot of minor geographical variation. Over 9000 species names have been published in Hieracium but some botanists regard many of those as synonyms of larger species.

Famous quotes containing the word species:
“Both classically- and romantically-minded spirits—inasmuch as these two species always exist—occupy themselves with a vision of the future: but the former do so out of a strength of their age, the latter out of its weakness.”
—Friedrich Nietzsche (1844–1900)
“Genius detects through the fly, through the caterpillar, through the grub, through the egg, the constant individual; through countless individuals the fixed species; through many species the genus; through all genera the steadfast type; through all the kingdoms of organized life the eternal unity. Nature is a mutable cloud which is always and never the same.”
—Ralph Waldo Emerson (1803–1882)
“An unjust law is itself a species of violence. Arrest for its breach is more so.”
—Mohandas K. Gandhi (1869–1948)
