Plant from a dry climate capable of conserving water for longer that other plants, due to structural adaptations like dense pubescence, thick epidermis and resin cover which delay transpiration. Certain mangrove plants are also xerophytes, because water absorption is hindered by excess of salt.
Hybrid: Plant derived from two genetically different parents. Crossed pollination is common among plants of different species within the same genus. Plants that originate from such crosses are called primary hybrids and generally possess some of the characteristics of both parents, but can be more similar to one than the other. Crossed pollination is also possible, although rare, among plants of different genera, as Fatshedera, a hybrid between Fatsia with Hedera. These crosses are called bigeneric or intergeneric hybrids. Several naturally generated hybrids are sterile.
