Ravenea Glauca Kz1
''Ravenea'' is a genus of 20 known species of palms, all native to Madagascar and the Comoros. 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 the species are endangered. Species such as ''R. moorei'' are critically so, with only two specimens known, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 th ...

Least Concern
A least-concern species is a species that has been categorized by the International Union for Conservation of Nature (IUCN) as evaluated as not being a focus of species conservation because the specific species is still plentiful in the wild. They do not qualify as threatened, near threatened, or (before 2001) conservation dependent. Species cannot be assigned the "Least Concern" category unless they have had their population status evaluated. That is, adequate information is needed to make a direct, or indirect, assessment of its risk of extinction based on its distribution or population status. Evaluation Since 2001 the category has had the abbreviation "LC", following the IUCN 2001 Categories & Criteria (version 3.1). Before 2001 "least concern" was a subcategory of the "Lower Risk" category and assigned the code "LR/lc" or lc. Around 20% of least concern taxa (3261 of 15636) in the IUCN database still use the code "LR/lc", which indicates they have not been re-evalua ...

Odoardo Beccari
Odoardo Beccari (16 November 1843 – 25 October 1920) was an Italian botanist famous for his discoveries in Indonesia, particularly New Guinea, and Australia. He has been called the greatest botanist to ever study Malesia. His author abbreviation is when citing a botanical name. Life Youth and education (1843–1864) Odoardo Beccari was born in Florence as the third child of Giuseppe di Luigi Beccari and the first child of Antonietta Minucci. After he lost his mother in early infancy and his father in 1849, he was brought up by a maternal uncle Minuccio Minucci. From 1853–1861, he attended the prestigious secondary school Real Collegio in Lucca. Here, one of his teachers was abbot Ignazio Mezzetti (1821–1876), a passionate collector of botanical specimens, who inspired him to pursue botany and assemble a herbarium. He later named the genus Mezzettia in his honor. In August 1861, he commenced his studies at the University of Pisa. Here he quickly captured the atte ...
