New record of Sicyos angulatus in Bulgaria
Sicyos angulatus (Cucurbitaceae, EPPO List of IAP) is recorded for the first time in Bulgaria. It was found in the Danubian Plain on the Belene (Persin) Island, and more specifically on the eastern part of the island in natural habitats near the Gurdata canal. It was found growing along riverbanks and in riverine forests. The species was found in association with another invasive plant: Amorpha fruticosa (Fabaceae, EPPO List of IAP). The blossom and fruiting period of S. angulatus is supposed to be from July to September or October. It is suspected that S. angulatus entered Bulgaria via the Danube from Romania and Central Europe.
