Abstract

Checklist of vascular flora of the Toruño hill (Alcores region, Alcalá de Guadaira, Seville). Located in Los Alcores region, the Cerro del Toruño is a calcarenitic hill included in Sevilla�s metropolitan area. It is protected by provincial regulations due to the value and naturalness of its vegetation. The aim of this study is to catalogue its flora and highlight its importance as a patch of relict natural vegetation within a strongly anthropic landscape. We recorded 351 species, of which 324 are native and three included in the Andalusian red list. The checklist includes 4 new chorological records at the provincial level and 16 at the regional level. Species diversity is comparable to nearby areas, given its habitat heterogeneity. The wild olive copse, Mediterranean fan palm formations, and xerophilous scrublands on calcarenitic rocks display a better conservation situation and are briefly commented. Finally, we discuss the biogeographic importance of Los Alcores region as an edaphic island, surrounded by the mostly clayey Guadalquivir valley, for calcicolous and coastal sand species
