Korthalsia Rogersii
''Korthalsia rogersii'' is an endangered endemic rattan species, thought to be extinct from the insular habitat of the Andaman Islands in the Indian Ocean until 1993. ''Korthalsia rogersii'' was first described by Odoardo Beccari in 1918 based on two herbarium field specimens collected by C. G. Rogers in 1904 from the South Andaman Island. This species was known only from these two collections until 1993. Sam Mathew and Pakshirajan Lakshminarasinhan (Botanical Survey of India) were able to find the species again at Chidiyatapu forests of the South Andamans after a gap of about 100 years. Live collections are introduced at Tropical Botanical Garden and Research Institute "Jawaharlal Nehru Tropical Botanic Garden and Research Institute", (formerly Tropical Botanic Garden and Research Institute) renamed in the fond memory of visionary Prime Minister of India Shri Pandit Jawaharlal Nehru is an autonomous Institute ..., Trivandrum, South India.

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 attent ...

Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ...

Rattan
Rattan, also spelled ratan, is the name for roughly 600 species of Old World climbing palms belonging to subfamily Calamoideae. The greatest diversity of rattan palm species and genera are in the closed-canopy old-growth tropical forests of Southeast Asia, though they can also be found in other parts of tropical Asia and Africa. Most rattan palms are ecologically considered lianas due to their climbing habits, unlike other palm species. A few species also have tree-like or shrub-like habits. Around 20% of rattan palm species are economically important and are traditionally used in Southeast Asia in producing wickerwork furniture, baskets, canes, woven mats, cordage, and other handicrafts. Rattan canes are one of the world's most valuable non-timber forest products. Some species of rattan also have edible scaly fruit and heart of palm. Despite increasing attempts in the last 30 years at commercial cultivation, almost all rattan products still come from wild-harvested plants. ...

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ...

Andaman Islands
The Andaman Islands () are an archipelago in the northeastern Indian Ocean about southwest off the coasts of Myanmar's Ayeyarwady Region. Together with the Nicobar Islands to their south, the Andamans serve as a maritime boundary between the Bay of Bengal to the west and the Andaman Sea to the east. Most of the islands are part of the Andaman and Nicobar Islands, a Union Territory of India, while the Coco Islands and Preparis Island are part of the Yangon Region of Myanmar. The Andaman Islands are home to the Andamanese, a group of indigenous people that includes a number of tribes, including the Jarawa and Sentinelese. While some of the islands can be visited with permits, entry to others, including North Sentinel Island, is banned by law. The Sentinelese are generally hostile to visitors and have had little contact with any other people. The government protects their right to privacy. History Etymology In the 13th century, the name of Andaman appears in Late Middle ...

Indian Ocean
The Indian Ocean is the third-largest of the world's five oceanic divisions, covering or ~19.8% of the water on Earth's surface. It is bounded by Asia to the north, Africa to the west and Australia to the east. To the south it is bounded by the Southern Ocean or Antarctica, depending on the definition in use. Along its core, the Indian Ocean has some large marginal or regional seas such as the Arabian Sea, Laccadive Sea, Bay of Bengal, and Andaman Sea. Etymology The Indian Ocean has been known by its present name since at least 1515 when the Latin form ''Oceanus Orientalis Indicus'' ("Indian Eastern Ocean") is attested, named after Indian subcontinent, India, which projects into it. It was earlier known as the ''Eastern Ocean'', a term that was still in use during the mid-18th century (see map), as opposed to the ''Western Ocean'' (Atlantic Ocean, Atlantic) before the Pacific Ocean, Pacific was surmised. Conversely, Ming treasure voyages, Chinese explorers in the Indian Oce ...

Trivandrum
Thiruvananthapuram (; ), also known by its former name Trivandrum (), is the capital of the Indian state of Kerala. It is the most populous city in Kerala with a population of 957,730 as of 2011. The encompassing urban agglomeration population is around 1.68 million. Located on the west coast of India near the extreme south of the mainland, Thiruvananthapuram is a major information technology hub in Kerala and contributes 55% of the state's software exports as of 2016. Referred to by Mahatma Gandhi as the "Evergreen city of India", the city is characterised by its undulating terrain of low coastal hills. The present regions that constitute Thiruvananthapuram were ruled by the Ays who were feudatories of the Chera dynasty. In the 12th century, it was conquered by the Kingdom of Venad. In the 18th century, the king Marthanda Varma expanded the territory, founded the princely state of Travancore, and made Thiruvananthapuram its capital. Travancore became the most dominan ...

Calamoideae
Calamoideae is a subfamily of flowering plant in the palm family found throughout Central America, South America, Africa, India, China, Southeast Asia and Australia. It is represented by 21 genera - containing nearly a quarter of all species in the palm family - including the largest genus, ''Calamus'', the type genus of the group. Only four are found in the New World while the rest are Old World denizens, usually found in equatorial swampland or along tropical coastlines. While the many species show marked differences, the bracts of all orders are tubular, the flowers are almost always borne in dyads or dyad derivatives, but most marked as an identifier among these palms are the overlapping scales covering the fruit; occasionally small and irregular they are, in most cases, neatly aligned in vertical rows. Also common to the group are varying forms of armament: spines along leaf margins or on sheaths, root and stem spines, reflexed rachis cirri, or specialized hooks among the ...

Endangered Plants
As of September 2016, the International Union for Conservation of Nature (IUCN) lists 3654 endangered plant species. 17% of all evaluated plant species are listed as endangered. The IUCN also lists 99 subspecies and 101 varieties as endangered. No subpopulations of plants have been evaluated by the IUCN. For a species to be considered endangered by the IUCN it must meet certain quantitative criteria which are designed to classify taxa facing "a very high risk of exintction". An even higher risk is faced by ''critically endangered'' species, which meet the quantitative criteria for endangered species. Critically endangered plants are listed separately. There are 6147 plant species which are endangered or critically endangered. Additionally 1674 plant species (7.6% of those evaluated) are listed as '' data deficient'', meaning there is insufficient information for a full assessment of conservation status. As these species typically have small distributions and/or populations, t ...
