Few-leaved Hawkweed


Hieracium murorum agg

Taxonomic note: Hawkweeds are apomictic and consist of a huge number of microspecies.  Apart from a handful of experts, everyone (including myself) records all yellow-flowered hawkweeds as Hieracium agg.  The red-flowered H aurantiacum is not included in Hieracium agg and is here treated separately.
