I suppose this quote on the web reflects the problem - "Plants of the Mediterranean scrub
The Mediterranean scrub may be divided into tall scrub, with well-developed trees that can provide shade and humidity to the undergrowth, and short scrub, made up of impassable shrubs and bushes, called garrigue. This biome contains evergreen broad-leaved and aciform trees, including: holm oaks, arbutuses, olive trees, laurels, carob trees, pine trees, junipers, cypresses and others. It also includes shrubby plants, for instance rock roses, mastic trees, myrtle and rosemary. "
