The rock forms a small polígala woody vine with a root that penetrates into the cracks of the rocks; of this root sprout many branches hard and short, which are filled with narrow, pointed leaves, supported by a corner so short that it passes unnoticed. The flowers are borne in short axillary clusters, often reduced to one or two flowers pale green. The fruit is a capsule flattened. The plant has a bitter grassy flavor soon.
This shrub grows in cracks in rocks and on rocky hillsides, mainly on limestone soils of eastern-and southern Peninsula and the Balearic Islands.
