A Palm By Many Names

This is a palm of the Arecaceae family, now correctly known as Chrysalidocarpus decaryi, though it has long circulated under the name Dypsis decaryi. It is not native to Britain or Ireland, and gardeners will find it catalogued under either name in different sources.

A Name With History

The plant was first formally published under the name Dypsis decaryi in 1995, in the work Palms of Madagascar, by Beentje and Dransfield. Kew's taxonomic record notes it as a synonym of Chrysalidocarpus decaryi, reflecting a reclassification that has moved this species between genera over time.
