Hyophorbe amaricaulis (also known as the "loneliest palm") [2] is a species of palm tree of the order Arecales, family Arecaceae, subfamily Arecoideae, tribe Chamaedoreeae. It is found exclusively on the island of Mauritius, and only a single surviving specimen [3] has been documented in the Curepipe Botanic Gardens in Curepipe. Thus, it is classified as an endling.
This species is one of nine species of palm which are indigenous to Mauritius, and one of the seven palms which are also endemic.
In the 1700s, this palm species was described from specimens taken from the mountain Pieter Both, where it seems to have been widespread at the time. [4]
Currently, only the single specimen exists in Curepipe Botanic Gardens, [5] and it is not known if this specimen was planted here, or was a survivor from the area's wild population that became included when the gardens were established.
The palm is about 12 metres (39 ft) high with a relatively thin gray trunk with a waxy crown shank.
It is related to the bottle palm and spindle palm. It is said to resemble the green variety of H. indica – another Hyophorbe palm species which also does not develop a swollen trunk.
It is reported to have white to cream-colored flowers on an inflorescence with three-ordered branching. Its fruits are 3.8 cm (1.5 in) long and a dull red colour, but years and years of efforts have not resulted in fertile offspring.
A study in 2010 reported successful germination in vitro (by isolating and growing embryos extracted from seeds in tissue culture). The young green seedlings grew for about three months but later died. [6]
Pieter Both, sometimes referred to as Peter Botte Mountain, is the second highest mountain of Mauritius, at 820 metres (2,690 ft) tall. The mountain is slightly shorter than Piton de la Petite Rivière Noire by eight metres. It is named after Pieter Both, the first Governor-General of the Dutch East Indies. It is located in the Moka Range.
Jubaea is a genus of palms with one species, Jubaea chilensis, commonly known in English as the Chilean wine palm or Chile cocopalm, and palma chilena in Spanish. It is native to southwestern South America and is endemic to a small area of central Chile between 32°S and 35°S in southern Coquimbo, Valparaíso, Santiago, O'Higgins, and northern Maule regions.
The wildlife of Mauritius consists of its flora and fauna. Mauritius is located in the Indian Ocean to the east of Madagascar. Due to its isolation, it has a relatively low diversity of wildlife; however, a high proportion of these are endemic species occurring nowhere else in the world. Many of these are now threatened with extinction because of human activities including habitat destruction and the introduction of non-native species. Some have already become extinct, most famously the dodo which disappeared in the 17th century.
Sonchus brassicifolius, synonym Dendroseris litoralis, is a species of flowering plant in the daisy and sunflower family Asteraceae. It is a small evergreen tree species known as the cabbage tree. It is endemic to the Juan Fernández Islands, which lie in the southeast Pacific, off the west coast of Chile. It is native only to the tiny, volcanic Robinson Crusoe Island, home of the famed Juania australis and many other endemic plants. The species is threatened by habitat loss and has been brought back from the brink of extinction. It had been reduced to only a few individuals by feral goats on the island, and is still considered critically endangered.
Hyophorbe indica, known commonly as palmier bâtard, palmiste poison, or champagne palm, is a species of flowering plant in the family Arecaceae. It is endemic to the island of Réunion. It is threatened by habitat loss.
Hyophorbe is a genus of five known species of flowering plants in the family Arecaceae, native to the Mascarene Islands in the Indian Ocean. All five species can attain heights of over 6 meters, and two of the species develop swollen trunks that have made them popular as ornamentals, but all of them are endangered in the wild.
Hyophorbe lagenicaulis, the bottle palm or palmiste gargoulette, is a species of flowering plant in the family Arecaceae. It is native to Round Island, Mauritius.
Hyophorbe vaughanii is a species of flowering plant in the family Arecaceae that is endemic to Mauritius. Its natural habitat is subtropical or tropical dry forests.
Hyophorbe verschaffeltii, the palmiste marron or spindle palm, is a critically endangered species of flowering plant in the family Arecaceae. It is endemic to Rodrigues island, Mauritius, but is widely grown in cultivation.
Juania australis, the Chonta palm, is a species of flowering plant in the family Arecaceae, the only species in the genus Juania. It is a solitary trunked palm tree which is endemic to the Juan Fernández Islands archipelago in the southeast Pacific Ocean west of Chile.
Normanbya is a monotypic genus of palms containing the single species Normanbya normanbyi, which is known by the common name black palm It is endemic to Queensland, Australia and is threatened by habitat destruction.
Roscheria is an endangered, monotypic genus of flowering plant in the palm family. The genus is named for Albrecht Roscher, a 19th-century German explorer, and the epithet for its single species R. melanochaetes derives from Latin and Greek meaning 'black' and 'bristle', alluding to the spines covering the trunks. They naturally occur on the Mahé and Silhouette Islands of Seychelles where they grow in mountainous rainforest and are threatened by habitat loss.
Hemithrinax ekmaniana is a palm which is endemic to Cuba. Only a single population of less than 100 mature individuals remains in the wild.
Curepipe Botanic Gardens in Route des Jardins, Curepipe, is the second largest botanical garden in Mauritius.
An endling is the last known individual of a species or subspecies. Once the endling dies, the species becomes extinct. The word was coined in correspondence in the scientific journal Nature.
Cylindrocline lorencei is a small tree that was native to the island of Mauritius, with only one specimen ever observed in the wild. By 1990 the species was considered extinct, and the only available seed could not be germinated. Brest Botanic Gardens successfully performed in vitro culture of a viable part of the seed embryo, saving the plant from extinction. Through further vegetative propagation at Brest and Kew Botanic Gardens, a small population of Cylindrocline lorencei has been grown and efforts are now underway to re-establish it in its native habitat.
Ramosmania is a genus of two species of small trees in the family Rubiaceae; one is extinct. Both species are endemic to the island of Rodrigues, Mauritius.
Diospyros revaughanii is a rare species of tree in the family Ebenaceae (ebony).
Dracaena umbraculifera is a species of flowering plant in the family Asparagaceae. It is a tree that was only known from botanical gardens since the end of the 18th century, the original sample was labelled as originating from the island nation of Mauritius. It was declared to be extinct by the IUCN in 1997. This was clearly incorrect, as there are living specimens in botanical gardens around the world. Searches on Mauritius failed to find any trees, however, so it was thought that the IUCN probably should have more correctly assessed the species as 'extinct in the wild'. As such a team of researchers at the Missouri Botanical Garden decided to 'reintroduce' the species back to Mauritius in 2011, clones were propagated by cuttings and planted out in Mauritius in 2012.
Butia campicola is a very small species of Butia palm with an underground trunk; native to the cerrados of central Paraguay and south-central Brazil.
