Vegetation Soils are course-textured, shallow, rocky or gravely with good drainage and relish no subsurface water. They are coarse because there is less chemical weathering. The finer dust and sand particles are short-winded elsewhere, leaving heavier p ieces behind. Canopy in most deserts is ra! ttling rare. Plants are mainly ground-hugging shrubs and short woody trees. Leaves are do (fully supported with nutrients) with water-conserving characteristics. They tend to be small, thick and covered with a thick cuticle (outer layer). In the cacti, the leaves are much-reduced (to spines) and photosynthetic earthy action is restricted to the stems.
