  rdf:value "Velamen is multiseriate, spongy layer of root epidermis that is composed of dead and air-filled cells. It is capable of rapid absorption and storage of water. It protects the root against excessive heating and water loss. It is mostly present in aerial roots of epiphytes."@en, "Capa esponjosa multiserial de la epidermis de las raíces, compuesta por células muertas y llenas de aire.
