Název v původním jazyce

A new invasive hawkweed, Hieracium glomeratum (Lactuceae, Asteraceae), in the Pacific Northwest

Popis výsledku v původním jazyce

In 2001, a new species of exotic hawkweed (Hieracium glomeratum) was identified from specimens collected in SE British Columbia and E Washington state. The specimens had at first been erroneously identified as the closely related H. caespitosum. A surveyof flora and herbaria records revealed H. glomeratum is a new species record for N America. DNA fingerprints of plants from different localities were identical. Their clonality along with a spot-like distribution indicates that this apomictic species probably originated from a single introduction from Europe. This species adds to the complex of 14 other exotic Hieracium species belonging to the Eurasian subgenus Pilosella that are adventive in the US and Canada. A distribution map of the native and adventive range of H. glomeratum and a key to distinguish it from related species in subgenus Pilosella that occur in North America is provided. The evolutionary and invasive potential of H. glomeratum is discussed.
