Duguetia Tobagensis
''Duguetia tobagensis'' is a small tree in the plant family Annonaceae which is endemic to Trinidad and Tobago. The species is only known from Tobago. Description ''Dugetia tobagensis'' is a small tree, the height of which is unknown. The leaves are long and wide. Flowers are borne among the leaves on inflorescences with 2 to 4 flowers. The petals are cream-coloured, long and wide. The fruit of the species has never been collected. Taxonomy The species was first described as ''Alcmene tobagensis'' by German botanist Ignatz Urban in 1921. Urban's description was based on a collection made by Walter Elias Broadway in Tobago in 1912. It was transferred to the genus ''Duguetia'' by Robert Elias Fries in 1934. ''Duguetia tobagensis'' is very similar to '' D. pycnastera''. In their 2001 monograph on the genus ''Duguetia'' Paul Maas and colleagues expressed doubts as to whether the two plants were actually different species, but preferred to keep the two species separate ...

Ignatz Urban
Ignatz Urban (7 January 1848 – 7 January 1931) was a German botanist. He is known for his contributions to the flora of the Caribbean and Brazil, and for his work as curator of the Berlin Botanical Garden. Born the son of a brewer, Urban showed an interest in botany as an undergraduate. He pursued further study at the University of Bonn and later at the University of Berlin where he gained a doctorate in 1873. Urban was appointed by A. W. Eichler to run the Berlin Botanical Garden and supervised its move to Dahlem. He also worked as Eichler's assistant on the ''Flora Brasiliensis'', later succeeding him as editor. In 1884 Urban began working with Leopold Krug on his Puerto Rican collections, a collaboration would later produce the nine-volume '' Symbolae Antillanae'', one of his most important contributions, and his 30-part ''Sertum Antillanum''. Urban's herbarium, estimated to include 80,000 or more sheets, was destroyed when the Berlin Herbarium was bombed in 1943 ...

Endemic Flora Of Trinidad And Tobago
The endemic flora of Trinidad and Tobago includes a total of 59 species of vascular plants belonging to 34 plant families. This is less than 3% of the total vascular plant flora of Trinidad and Tobago. Thirty-nine of these species are endemic to Trinidad, 12 are Tobagonian endemics, and six are present on both islands. Island systems tend to be rich centres of endemism as a result of their isolation. The islands of the Greater Antilles have rates of endemism which range from 12-50% of their flora. Trinidad and Tobago has a far lower rate of endemism, probably as a result of its geological history. The islands of Trinidad and Tobago lie on the South American continental shelf, and were both connected to the mainland during the Pleistocene. Tobago was separated from the mainland about 13,000 years ago; Trinidad was connected until more recently, and may only have become separated about 1,500 years ago. The flora of Trinidad and Tobago has been estimated to include about 2,50 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. There are currently 5196 animals and 6789 plants classified as Vulnerable, compared with 1998 levels of 2815 and 3222, respectively. 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 tax ...

IUCN Red List
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The aim of the IUCN Red List is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to reduce species extinction. According to IUCN the formally stated goals of the Red List are to provi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Main Ridge (Tobago)
Main Ridge is the main mountainous ridge on the island of Tobago, Trinidad and Tobago. It is a chain of hills which runs from southwest to northeast between the Caribbean Sea and the Southern Tobago fault system and reaches a maximum height of . The Main Ridge Forest Reserve, which was legally established in 1776, is one of the oldest protected areas in the world. It is a popular site for birdwatching and ecotourism. Main Ridge provides important habitat for native plants and animals, including several species endemic to Tobago. History The Treaty of Paris in 1763 ended Tobago's status as a neutral territory and made it a British colony. The Treaty of Aix-la-Chappelle in 1748 had designated Tobago neutral territory and left it in the hands of its remaining indigenous population, but the return to British control led to a rapid conversion of the island to a plantation economy. Under the direction of the Board of Trade, the island was surveyed, divided into plots, and sold to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Inflorescence
An inflorescence is a group or cluster of flowers arranged on a stem that is composed of a main branch or a complicated arrangement of branches. Morphologically, it is the modified part of the shoot of seed plants where flowers are formed on the axis of a plant. The modifications can involve the length and the nature of the internodes and the phyllotaxis, as well as variations in the proportions, compressions, swellings, adnations, connations and reduction of main and secondary axes. One can also define an inflorescence as the reproductive portion of a plant that bears a cluster of flowers in a specific pattern. The stem holding the whole inflorescence is called a peduncle. The major axis (incorrectly referred to as the main stem) above the peduncle bearing the flowers or secondary branches is called the rachis. The stalk of each flower in the inflorescence is called a pedicel. A flower that is not part of an inflorescence is called a solitary flower and its stalk is al ...
