| In the Mediterranean climate, heliophilia is merely a means of securing the xeromorphic adaptation that is necessary if the plants are to survive the difficult period of their first years of life. |
|
| Most of the hydromorphic and xeromorphic modifications found among dicot leaves, however, also occur in monocot leaves in similar environments. |
|
| Most xeromorphic leaves have a high volume-to-surface ratio i.e., they are small and compact. |
|
| Under xeromorphic conditions, the leaf has adopted features that decrease water loss. |
|
| Most bennettitalean foliage shows xeromorphic features such as small, reflexed pinnae, sunken stomata, and papillae or hairs on the leaf surfaces. |
|
| Xeromorphic adaptations to arid conditions are quite varied and tend to prevent water loss during periods when water is limited and must be conserved by the plant. |
