Related to Nephrolepsis: Nephrolepis exaltata
a genus of epiphytic or terrestrial ferns of the family Oleandraceae (sometimes assigned to the family Davalliaceae). The shortened stems of Nephrolepis yield thin horizontal shoots, on which new frond rosettes develop. The fronds are compound pinnate; they retain apical growth for several years, attaining a length of 3 m or more (for example, Nephrolepis biserrata and N. cordifolia). The sori are located at the margin and are equipped with reniform indusia. There are about 30 species in the tropics of both hemispheres. Some species, including N. exaltat and N. acuminata and their numerous ornamental forms, are raised indoors.
