Oleandra is a genus of ferns. In the Pteridophyte Phylogeny Group classification of 2016 (PPG I), it is the only genus in the family Oleandraceae, which is placed in suborder Polypodiineae, order Polypodiales.[1] Alternatively, the family may be placed in a very broadly defined family Polypodiaceae sensu lato as the subfamily Oleandroideae.[2]

The genus contains about 15 species.[1] Most are erect ground ferns or scandent epiphytes that start from the ground. The lamina (leafy area of the fronds) are simple or pinnate, and the individual pinnae are articulate to the rachis. The sporangia are contained in discrete round sori in a single row on either side of the midrib of the fronds.[citation needed]
