Ravenea
''Ravenea'' is a genus of 20 known species of 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 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. Species Most of ...

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 Albicans
''Ravenea albicans'' is a species of flowering plant in the Arecaceae family. It is a palm endemic to northeast Madagascar and found in seven fragmented locations between the towns of Ampasimanolotra and Antalaha with the exception of one location much further south near Vondrozo. It is an endangered species threatened by habitat loss. There are perhaps 200 mature individuals remaining. In its natural range it tends to grow in humid forests within northeast Madagascar's mountain valleys. It is unique among the ''Ravenea'' genus because its pinnate leaves have an exotic, colorful appearance. Its species name, ''albicans'', is derived from the Latin word for the color white, album, as is the word for albinism. The base of each frond is green, yet they become white to dark grey near the tip at maturity. Some individuals have completely white fronds. References albicans ''Albicans'' (Latin, 'whitening') may refer to: * Corpus albicans The corpus albicans (Latin for "white ...

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.
