Updates on the vascular flora of Castellón and Valencia (Valencian Community, Spain). Updates on the vascular flora of Castellón and Valencia

Fieldwork in the autumn of 2023 in the Spanish provinces of Castellón and Valencia yielded some interesting plant records, mainly (but not exclusively) of non-native taxa. Their degree of naturalization varies from ephemeral garden escapes (such as Clerodendrum trichotomum or Erythrina crista-galli) to well-established, fast-spreading weeds (such as Chloris truncata). Arthraxon hispida is reported for the first time in Spain.
