Vivipary is the phenomenon of having seeds germinating within the fruit, eg, halophytes (mangrove plants).
Sunken stomata are found in xerophytes, heterophylly (occurrence of different kinds of leaves in a single plant) is found in hydrophytes, while velamen tissue is found in epiphytes.
Velamen provides a mechanical function protecting the vascular tissues in the root cortex, shielding the root from transpirational water loss. It also adhered the plant to the substrate.
