| Description
| - V roce 2001 byl mezi herbářovými sběry ze SV části Britské Kolumbie a V části státu Washington zjištěn nový nepůvodní druh jestřábníku – Hieracium glomeratum. Sběr byl původně určen jako Hieracium caespitosum. Revize herbářového materiálu a literárních pramenů ukázala, že jde o první nález tohoto druhu v Severní Americe. DNA fingerprinty rostlin z různých lokalit byly stejné. Klonalita spolu se značně nespojitým areálem indikují že jde o apomikty, současné rozšíření je zřejmě výsledkem pouze jedné introdukce z Evropy. Druh se řadí do skupiny 14 dalších v Severní Americe nepůvodních druhů podrodu Pilosella eurasijského původu. Článek obsahuje mapu rozšíření (původní i nepůvodní areál) a klíč na rozlišení od podobných druhů. Diskutován je evoluční a invazní potenciál druhu. (cs)
- 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 survey of 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.
