Identification. Characterized by long-creeping stems with bicolorous peltate scales, stipes articulate to phyllopodia, undivided, elliptical laminae, and free veins. Sori round, indusiate, the indusia bicolorous and attached at a narrow sinus. It could be confused with some species of Elaphoglossum Schott ex J.Sm.   , which differ by nonpeltate stem scales, ascending veins (vs veins nearly perpendicular to the midrib in Oleandra   ), and acrostichoid sori.

Distribution and habitat. Endemic to RPPN Guaricica; known from only two collections. Terrestrial, hanging on steep slopes in montane forests.

Order Polypodiales   (suborder Polypodiineae   ), Polypodiaceae J.Presl & C.Presl
