Few-leaved Hawkweed


Hieracium murorum agg

Taxonomic note: Hawkweeds are apomictic and consist of a huge number of microspecies.  Here they are divided into just two groups: few-leaved and many-leaved.  Another two species, H aurantiacum and H pilosella, both very distinctive, are treated separately.
