Chorological notes on the Sicilian endemic Euphorbia papillaris (Euphorbiaceae)

Abstract

Thanks to the discovery of a new important site in the Trapani Mountains, the distribution of Euphorbia papillaris, a rare plant endemic to N-W Sicily, is revised. On the basis of the unpublished record, one of the two hypotheses on the discovery of the species in Sicily, previously advanced, is here confirmed. Floristic and ecological information on the new locality are also provided.
