Hieracium lachenalii

The species was widely known for many years as H. vulgatum,[http://www.efloras.org/florataxon.aspx?flora_id=1&taxon_id=250066961 Flora of North America, Hieracium vulgatum Fries, 1819. ] but more recent studies have indicated that the two names represent the same species. The name H. lachenalii was coined in 1802,[http://www.ipni.org/ipni/idPlantNameSearch.do?id=327414-2&back_page=%2Fipni%2FeditAdvPlantNameSearch.do%3Ffind_infragenus%3D%26find_geoUnit%3D%26find_includePublicationAuthors%3Dtrue%26find_addedSince%3D%26find_family%3D%26find_genus%3DHieracium%26find_infrafamily%3D%26find_rankToReturn%3Dspec%26find_publicationTitle%3D%26find_authorAbbrev%3D%26find_infraspecies%3D%26find_includeBasionymAuthors%3Dtrue%26find_modifiedSince%3D%26find_species%3Dlachenalii%26output_format%3Dnormal The International Plant Names Index, Hieracium lachenalii ] and H. vulgatum in 1819,[http://www.ipni.org/ipni/idPlantNameSearch.do?id=327415-2&back_page=%2Fipni%2FeditAdvPlantNameSearch.do%3Ffind_infragenus%3D%26find_geoUnit%3D%26find_includePublicationAuthors%3Dtrue%26find_addedSince%3D%26find_family%3D%26find_genus%3DHieracium%26find_infrafamily%3D%26find_rankToReturn%3Dspec%26find_publicationTitle%3D%26find_authorAbbrev%3D%26find_infraspecies%3D%26find_includeBasionymAuthors%3Dtrue%26find_modifiedSince%3D%26find_species%3Dvulgatum%26output_format%3Dnormal The International Plant Names Index, Hieracium vulgatum ] so per taxonomic regulations, the older name is to be used, with H. vulgatum delegated to being a synonym.

This common weed can grow and produce flowers on plants that range from {{convert|4|in|cm|abbr=off|sp=us}} to {{convert|36|in|cm}} tall. The rhizome is short and stout. The broadly elliptic leaves can be up to {{convert|5|in|cm|abbr=off|sp=us}} long and taper with teeth towards the base.{{cite web|url=http://msuplants.com/pd.asp?pid=3104

Bracts surround the flower head; the receptacle (basal part of the flower on which the florets are attached) is flat and naked; heads tend to start together then become somewhat solitary on long leafless stems.

The stalks below the heads are covered with scattered, simple and gland-tipped black hairs and contain a milky substance.

The pale yellow flowers are produced during all of the summer months. The fruit are dark brown achenes.
