Notes

This New World weed is increasingly naturalised in Europe ( Martini and Scholz 1998). In the Canary Islands, it was first reported from La Palma ( Otto et al. 2008). Since 2012, it is also known from two localities in Gran Canaria ( Marrero Rodríguez 2019). In December 2018, Eragrostis virescens was observed in relative abundance along dirt tracks in Santa Úrsula, for the first time in Tenerife.

This species looks fully naturalised. A further spread in similar habitats in the area can be expected.
