Erysimum bastetanum (G. Blanca & C. Morales) Lorite, Perfectti & Gómez comb. & stat. nov

Basionym: Erysimum baeticum (Heywood) Polatschek subsp. bastetanum G. Blanca & C. Morales. Anal. Jard. Bot. Madrid 49(2): 213– 214. Type: Spain: Granada, Sierra de Baza, Prados del Rey. 7–VI–1983. Leg: C. Morales et al. (Holotype GDAC 17430!).

This taxon could be differentiated from E. baeticum by some markedly morphological traits:

– Plants up to 30 (40) cm. Multiple stems, not ramified in the upper part; densely leafy. Siliques erect-patent to subpatent. Polycarpic. Short-lived perennial ......................................................................................................................................................... E. baeticum

E. bastetanum inhabits gaps of holm-oak ( Quercus ilex L.), mixed pine forests ( Pinus nigra Arnold and P. sylvestris L.) and shrublands from 800–2200 m a.s.l., mainly on limestones (rarely on mica schists and quartzites). E. baeticum appears usually in high-mountain shrublands ( Genista versicolor Boiss. , Cytisus galianoi Talavera & P.E. Gibbs and Juniperus communis L.) and perennial grasslands from 1500–2600 m a.s.l. only in metamorphic rocks (mica schists and quartzites). E. bastetanum is distributed across eastern part of Baetic mountains (Sierra de Baza, Sierra de Filabres, Mencal, Sierra de María-Orce, Sierra Jureña), while E. baeticum is a narrow endemic species of the eastern part of the Sierra Nevada ( Granada and Almería provinces).

After this proposal, the resulting two species are narrow endemics, especially E. baeticum . For this reason, we propose an evaluation of the conservation status of these species in order to apply, if needed, legal and management conservation measures.
