Common name

Description

The name O. lancifolium has been widely used in tropical Africa for plants with a narrow elliptic sterile leaf held at 60-85° from the horizontal and a linear rhizome. O. gracillimum, O. lusoafricanum, O. caroticaule have been identified within the O. lancifolium aggregate (Burrows and Edwards, 1993). Futhermore with the identification of O. sandieae, it has been concluded that the name O. lancifolium should only be used for plants from the Mascarenes and perhaps Madagascar (Crouch et al., 2011).
