Ravenea Beentjei
''Ravenea'' is a genus of 20 known species of Arecaceae, palms, all native to Madagascar and the Comoros. It is not to be confused with ''Ravenala'', a genus of superficially palm-like plants also from Madagascar. They are small to large, dioecious palms, with solitary, robust grey stems, swollen at base and gradually tapering upward. The species vary greatly in size, with ''R. hildebrandtii'' and ''R. nana'' only reaching 4 m, while ''R. robustior'' and ''R. sambiranensis'' both reach 30 m. The leaf, leaves are up to 2–5 m long, pinnately compound, reduplicate, erect at first then arching, twisted near the apex; with numerous crowded narrow ribbed leaflets. The inflorescence is short, borne among the leaves; the fruit is a red drupe. One particular species, ''Ravenea rivularis'', is commonly cultivated as a houseplant and grown indoors all over the world. However, it is actually considered a vulnerable species in its wild habitat with fewer than 900 trees growing naturally. S ...

Ravenea Rivularis
''Ravenea rivularis'', the majestic palm, or majesty palm, is a species of tree in the family Arecaceae. They generally grow to 10 to 12 feet tall and are often marketed in stores as a "houseplant" in a pot, in its natural state, the majesty palm may sometimes grow to tall. The palm has upward-arching leaves divided into long, thin fingers. It is native to Madagascar; however, it is believed only about 900 plants are currently alive in the wild according to an assessment conducted in 2010. The species grows in several regions of Madagascar, but because those regions are totally surrounded and separated by desert, the natural spread of the species is limited. Despite its fragility as a species in the wild, it has become a very popular houseplant due to its beautiful leaves and slow-growing nature. ''Ravenea rivularis'' grows in somewhat isolated humid habitats that are found in the otherwise dry, hot semi-arid climate of southwest Madagascar. Often, they grow huddled along the ...

Ravenea Louvelii
''Ravenea louvelii'' is a species of flowering plant in the Arecaceae family. It is a palm endemic to Madagascar, where it is known from a single location. There are fewer than 10 individuals left. They are believed to be in Andasibe-Mantadia National Park Andasibe-Mantadia National Park is a 155 square kilometre protected area, located about 150 km east of Antananarivo, consisting principally of primary growth forest in the Alaotra-Mangoro Region in eastern Madagascar.

Ravenea Latisecta
''Ravenea latisecta'' is a species of flowering plant in the family Arecaceae. As are most other species of palm tree in the genus ''Ravenea'', it is threatened by habitat loss and climate change. It is native to eastern central Madagascar. Here it is known to grow in a single protected area, the Andasibe-Mantadia National Park. However biologists haven't located this species in the wild since 1992, when four mature trees were identified. Consequently, ''Ravenea latisecta'' may be extinct in the wild but recently collected data is not available to confirm nor contradict this claim. As of now, the species remains classified as critically endangered An IUCN Red List critically endangered (CR or sometimes CE) species is one that has been categorized by the International Union for Conservation of Nature as facing an extremely high risk of extinction in the wild.

Vulnerable Species
A vulnerable species is a species which has been Conservation status, categorized by the International Union for Conservation of Nature as being threatened species, threatened with extinction unless the circumstances that are threatened species, threatening its survival and reproduction improve. Vulnerability is mainly caused by habitat loss or destruction of the species' home. Vulnerable habitat or species are monitored and can become increasingly threatened. Some species listed as "vulnerable" may be common in captivity (animal), captivity, an example being the military macaw. In 2012 there were 5,196 animals and 6,789 plants classified as vulnerable, compared with 2,815 and 3,222, respectively, in 1998. Practices such as cryoconservation of animal genetic resources have been enforced in efforts to conserve vulnerable breeds of livestock specifically. Criteria The International Union for Conservation of Nature uses several criteria to enter species in this category. A taxon ...
