|Scientific Name:||Hyophorbe amaricaulis|
|Red List Category & Criteria:||Critically Endangered B1+2abde, C1+2b, D ver 2.3|

Only one individual remains in the wild, hence the risk of extinction is very high. Intrinsic problems with the remaining plant also prevent pollination and any recruitment.
|Range Description:||Last individual existing in the wild and hence the risk of extinction is very high. Also intrinsic factors in the only plant preventing pollination. Last specimen of this species growing in Curepipe Botanical Garden. Had been reported in the past on the top of Peter Both Mountain. For a very long time it has been confused with H. ilagenicaulis (Round Island bottle palm). This single specimen has persisted within the Curepipe Botanical Garden for over fifty years, and flowers and fruits regularly. However, the fruits are sterile because the male flower open before the female, thus precluding any pollination. Although this palm does not produce viable seeds, plants have on several occasions, been cloned by tissue culture of the embryo at Wye, Edinburg, and Kew. Unfortunately, each time the plants were removed from sterile medium, they died.|

|Habitat and Ecology:||Tropical degraded forest (upland forest).|
|Major Threat(s):||Only individual existing in the wild. Hence very susceptible to disease, and cyclone. Prone to hybridization. No natural pollination because of intrinsic factors|
|Conservation Actions:||Collection are storage of pollen for self pollination under controlled conditions. Cloning of remaining genotype: Material has already sent to Kew Garden by National Parks and Conservation Service and they are using H. lagenicaulis as test plant whereby they have been successful with the somatic embryogenesis of the said species.|
