Aportacions respecte de la distribució i límits d'algunes de les espècies mediterràneo-estèpiques a Catalunya

The areas of distribution of 24 species of Mediterranean-stepic character (included in this term are Ibero-Mogrebine, Irano-Turanian, Saharo-Sindian species, as well as species endemic to arid peninsular zones), are delimited, of which the nordeast boundary in the Iberian Peninsula is placed in the Catalonian Region.
In the elaboration of these areas, unpublished data collected by the authors has been
used, as well as data gleaned from bibliographic references and herbarium material.
