This taxon resembles D. pilulifera but is distinct by the regular leaflets and the presence of scattered scales on the leaflets. (J. Dransfield and H. Beentje. 1995)/Palmweb.
A majestic, tristichous palm (the leaves are in three ranks). Although the material is incomplete, this is clearly a distinct taxon. The name derives from the local name. (J. Dransfield and H. Beentje. 1995)/Palmweb.
Sunny, moist, but well drained position. Filtered light when very young. Cold Hardiness Zone: 10a
Comments and Curiosities
The name tsaravoasira apparantly means "good with salt" in the local language. It thus doesn't really need to be said that the palm heart is eaten.
Conservation: Endangered. Only known from three sites, two of which are under agricultural pressure; numbers within the populations are low, and we have seen less than thirty altogether. (J. Dransfield and H. Beentje. 1995)/Palmweb.
Uses: Palm-heart edible and highly esteemed.
Floribunda Palms, Hawaii, Dr. John Dransfield makes positive identification 2008, Dypsis sp. 'cerecea' is now confirmed by John Dransfield as the real Dypsis ampasindavae, and Dypsis tsaravoasira is now a new type all together, D. ampasindavae, and Dypsis tsaravoasira are two totally different species, and no longer are associated.
