Lots of Cistaceae species are found in the Mediterranean and especially in Spain. Most of them are Cistus and Helianthemum species. This one is Halimium, a soft-hairy plant. I found it in Mediterranean scrubland in S Spain - Sierra del Chapparal, above Motril, 460 m
This is the dry 'skeleton' of the Mediterranean annual named - Helianthemum salicifolium. u can clearly see the 3 broad seapls that are so typical for this specues.
