OBS

"Xeromorph" is now used to describe any plant that has any of the characteristics listed by Warming as xeromorphic characters, [a well-developed coating of hairs; protected stomates; wax; thick cuticle; sclerophylly ...; mucilage; ericoid leaves like the heathers, or leaves reduced to stiff spines, or leafless (aphyllous) stems], irrespective of their function. ... A xerophyte is any plant that grows in a dry habitat. When [defined] in this way, we soon find that there are xerophytes that are not xeromorphs, and vice versa.
