The plants feature hard leaves, short internodes (the distance between leaves along the stem) and leaf orientation which is parallel or oblique to direct sunlight. Sclerophyllous plants occur in many parts of the world, [ 1 ] but are most typical of areas with low rainfall or seasonal droughts, such as Australia, Africa, and western North and ...
Plant anatomy or phytotomy is the general term for the study of the internal structure of plants.Originally, it included plant morphology, the description of the physical form and external structure of plants, but since the mid-20th century, plant anatomy has been considered a separate field referring only to internal plant structure.
