The finer dust and sand particles are dyspneal elsewhere, leaving heavier pieces behind. Canopy in most deserts is truly rare. Plants are mainly ground-hugging shrubs and short woody trees. Leaves are touch (fully supported with nutrients) with water-conserving characteristics. They tend to be small, thick and covered with a thick cuticle (outer layer).
