There are presented new data about Hésperis pýcnotricha in Romania. In 2004, the species was first identified in Gura Motrului Locality in Romania. Since then, the species has been pursued and so far, we have come up with new data on its origin and chronology. To our joy, the plant (ornamentally planted) has been identified in the same locality in a backyard adjacent to the first resort. Subsequently, the plant has been identified in other locations such as at the edge of abandoned farms and their premises in Cerna Valcea District; in some local households in PonoareleMehedinti District. Travelling in Turkey, at Marmara University in Erasmus, the author had the opportunity to see ornamental plants, inside the yard of DolmabahçePalace. Comparing the material collected from Turkey with that from Romania, he realized that both samples have the same morphologically characteristics. From bibliography sources, at the European level (like in Moldova, Slovakia, Turkey in Europe and Ukraine), it is known as a native plant or entered in Krym, Czech Republic, Lithuania and Russian Federation. The species is also known in Sweden while in Lithuania, it is mentioned in the list of invasive plants. The presence of the species in Romania, although was pointed out from 2004, is not consigned at the European level.
Key words: New chronology, Hésperis pýcnotricha, Romanian, flora.
