Catalogue of endernic, rare or threatened vascular plants in Catalonia. 1. Endemic taxa

This is the first of a set of papers devoted to rare or threatened plants in Catalonia. We list 279 specific or subspecific taxa which are in a broad sense endemic to the northeastern part of the Iberian Peninsula. We assess them with regard to their conservation status according to IUCN criteria. Assignment of these taxa to established categories has led to the following results: 6 taxa critically endangered (CR), 5 endangered (EN), 32 vulnerable (VU), 5 near threatened (LR nt), 841east concern (LR lc), 116 not threatened (NT) and 31 data deficient (DD). The small number of taxa that en joy legal protection in comparison with the number of threatened plants is emphasized.
