Youngia japonica (L.) DC. (Compositae), recently detected in Barcelona

Abstract

Youngia japonica, introduced accidentally in urban garden areas, is recorded for the first time from the Iberian Peninsula. It has maintained its presence in the place where it was first observed without expanding, and has reappeared over the following years. A possible means of introduction is along with Zoysia, species of grass used for forming lawns as an alternative to Bermuda grass.
