Notes
1. Variability: Density of hairs is variable, as is the distance of the sori to the costa.
2. Oleandra musifolia is distinguished from O. cumingii mainly by the short phyllopodia (long in O. cumingii). Incomplete collections are easily confused also with O. neriiformis but can often be recognized by the flat, softer rhizome usually without sclerenchyma strands (rhizome more rigid, rounded, with sclerenchyma strands in O. neriiformis) and by the catenate hairs with capitate apex (more acicular, not capitate in O. neriiformis). Distinguishing these two species on basis of juvenile material may be difficult, and is often impossible, while it may not be clear from herbarium material that the material is juvenile.
