All the sites I know from Spain (cited in Diels, 1906) are in the province
of Cadiz between Cadiz and Gibraltar:
Cadiz
Chiclana (de la Frontera)
Alcala de los Gazules
Jimena (de la Frontera)
Algeciras
N San Roque
Gibraltar
The site near Alcala has been confirmed (thousands of specimens) in
March 1996: El Picacho de Alcala de los Gazules NW Gibraltar above trail
approx.  2km from Alcala, ca.  750 m alt.  on S slope. 
Kind regards
