Jumelle & Perrier de la Bathie. Restricted_to Madagascar, this species has not been collected since 1947. I have found only four collections of this unusual species. A deliberate search should be made to determine if it is still extant. Hydnora esculenta is perhaps the most specialized of all members of the genus as the flowers are unisexual. The pistillate plants apparently have well developed staminodes.
Recently, Hydnora has been rediscovered in Madagascar. Is it Hydnora esculenta?? Check out the following web site. Madagascar
