Note: J. Agardh (1863 [1851–1863]: 1136) divided this widespread species into three taxa of unspecified rank, namely, 1. madagascariensis, 2. indica, and 3. australis. Because the type specimen (in Vahl's herbarium at C) is from India, the epithet indica is invalid at any rank, being pre-empted by the autonym fraxinifolia.
