Orobanche ramosa grows several branched stems of up to 60 cm in height from its sturdy root. The flowers are tubular, white, blue or purple, based on a calyx of yellowish sepals. The stems are thicker at the base and have small scales visible on them, instead of leaves. The stems are covered in glandular hairs. Much viable seed, fine as dust, is distributed after flowering (Wikipedia).
This flower was photographed in spring close to the beach at Onrus. It grew to only about 10 cm and by midsummer it was gone.
