 The type is not in Paris, and could not be traced in any other herbarium. We are suspi- pistillate inflorescence by Jumelle, and we believe he only saw part of the rachis, probably the proximal part. His statements about the inflorescence being solitary or multiple are notoriously unreliable; if the pistillate inflorescence is multiple, this taxon could be an extreme form of R. madagascariensis. We failed to find any pistillate trees in Mantady, and we have included the species in the key according to Jumelle"s description. (J. Dransfield and H. Beentje. 1995)/Palmweb.

 Conservation: Endangered. The species only occurs in a single site, and numbers are very low (we have seen four trees). (J. Dransfield and H. Beentje. 1995)/Palmweb.
-'''Conservation:''' Critically Endangered;  The palm has been collected only from Andasibe region, in the centre-east of Madagascar, inside the  protected area. Its population not been located in the wild since 1992, when it was last recorded only four mature trees were seen. Based on this information this species is listed as Critically Endangered under criterion D, because if it still exists, the numbers are likely to be very low and certainly under 50 mature individuals. Surveys are required to relocate this species to determine its status. There is a possibility that it might have gone extinct, but there have been insufficient targeted searches to even list it as Possibly Extinct. Known only from the Analamazaotra Reserve. Surveys are required to locate additional plants of this species to determine the full range, population size and trends and what threats may be impacting it. (ICUN Red List), edric.

-"Very rare species that is very attractive as a seedling; long slightly arching and twisted pinnate leaves with slightly drooping leaflets. As a mature palm it can look a bit like a solitary Ravenea madagascariensis. Floral features are used to differentiate... but to me looks a LOT different as a seedling." (Geoff Stein), edric.
