Osmelia
''Osmelia'' is a genus of flowering plants in the willow family, Salicaceae. ''Osmelia'' includes four species of trees native to Sri Lanka and Southeast Asia. ''Osmelia'' is closely related to the monotypic '' Pseudosmelia'' of Morotai and Halmahera of the Indonesian Maluku Islands and to the monotypic '' Ophiobotrys'' from west and west-central tropical Africa.

Ophiobotrys
''Ophiobotrys zenkeri'' is a species of tree native to tropical Africa from Ivory Coast to Gabon and is the only member of the genus ''Ophiobotrys''. Formerly classified in the Flacourtiaceae, phylogenetic analyses based on DNA data indicate that this species, along with its close relatives in the Asian genera '' Osmelia'' and '' Pseudosmelia'', are better placed in a broadly circumscribed Salicaceae. ''Ophiobotrys'' differs from its close relatives in having 5 sepals, 5(-6) stamens, one divided style, and terminal inflorescences 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 wood has several uses, and the species is known by several common names, including uolobo, urogbo, abuana, akwana, and bofan.

Salicaceae
The Salicaceae is the willow family of flowering plants. The traditional family (Salicaceae ''sensu stricto'') included the willows, poplar, aspen, and cottonwoods. Genetic studies summarized by the Angiosperm Phylogeny Group (APG) have greatly expanded the circumscription of the family to contain 56 genera and about 1220 species, including the Scyphostegiaceae and many of the former Flacourtiaceae. In the Cronquist system, the Salicaceae were assigned to their own order, Salicales, and contained three genera (''Salix'', ''Populus'', and '' Chosenia''). Recognized to be closely related to the Violaceae and Passifloraceae, the family is placed by the APG in the order Malpighiales. Under the new circumscription, all members of the family are trees or shrubs that have simple leaves with alternate arrangement and temperate members are usually deciduous. Most members have serrate or dentate leaf margins, and those that have such toothed margins all exhibit salicoid teeth; a sali ...

Pseudosmelia
''Pseudosmelia moluccana'' is a species of shrub or small tree native to Morotai and Halmahera of the Indonesian Maluku Islands and is the only member of the genus ''Pseudosmelia''. Formerly classified in the Flacourtiaceae, phylogenetic analyses based on DNA data indicate that this species, along with its close relatives in the Asian genus ''Osmelia'' and the African genus ''Ophiobotrys'', are better placed in a broadly circumscribed Salicaceae. ''Pseudosmelia'' differs from its close relatives in having thick, truncate staminodes and large, spindle-shaped fruits with numerous seeds. ''Pseudosmelia moluccana'' is known by the common name In biology, a common name of a taxon or organism (also known as a vernacular name, English name, colloquial name, country name, popular name, or farmer's name) is a name that is based on the normal language of everyday life; and is often contra ...

George Henry Kendrick Thwaites
George Henry Kendrick Thwaites (9 July 1812, Bristol – 11 September 1882, Kandy) was an English botanist and entomologist. Thwaites was initially an accountant and studied botany during his spare time. He was interested particularly in the lower plants such as the algae and the cryptogams. He became a recognised botanist when he showed that the diatoms are not animals, but algae. In 1846 he was lecturer on botany at the Bristol school of pharmacy and afterwards at the medical school. In March 1849, on the death of George Gardner, Thwaites was appointed superintendent of the botanical gardens at Peradeniya, Ceylon. A position he held for thirty years, until he resigned in 1879. He was made a Fellow of the Royal Society on 1 June 1865 following the publication of his ''Enumeratio Plantarum Zeylaniæ'', – (five fasciculi 1859–64). His notes form the most valuable portion of Frederic Moore Frederic Moore FZS (13 May 1830 – 10 May 1907) was a British entomologist an ...

Nicolai Stepanovitch Turczaninow
Nikolai Stepanovich Turczaninow ( ru , Николай Степанович Турчанинов, 1796 in Nikitovka, now in Krasnogvardeysky District, Belgorod Oblast, Russia – 1863 in Kharkov) was a Russian botanist and plant collector who first identified several genera, and many species, of plants. Education and career Born in 1796, Turczaninow attended high school in Kharkov. In 1814, he graduated from Kharkov University, before working as a civil servant for the Ministry of Finance in St. Petersburg. Soon after, in 1825, Turczaninow published his first botanical list. Despite being employed in a different field, he continued his largely self-taught botanical work. In 1828, he was assigned an administrative post in Irkutsk, Siberia. This allowed him to collect in the Lake Baikal area, which is known for its rich biodiversity. A spate of papers followed, and Turczaninow established his own herbarium containing plants from the region. In 1830, he was appointed a Fello ...

George King (botanist)
Sir George King (12 April 1840 – 12 February 1909) was a British botanist who was appointed superintendent of the Royal Botanic Garden, Calcutta in 1871, and became the first Director of the Botanical Survey of India from 1890. He was recognised for his work in the cultivation of cinchona and for setting up a system for the inexpensive distribution of quinine throughout India through the postal system. Early life George was born in Peterhead, Aberdeenshire, to Robert King and Cecilia Anderson. Robert King was a bookseller who moved to Aberdeen to partner with his brothers who were also in the book business. One brother Arthur was the founder of the Aberdeen University Press.

Tropical Africa
Although tropical Africa is mostly familiar to the West for its rainforests, this biogeographic realm of Africa is far more diverse. While the tropics are thought of as regions with hot moist climates, which are caused by latitude and the tropical rain belt, the geology of areas, particularly mountain chains, and geographical relation to continental and regional scale winds impact the overall areas , also, making the tropics run from arid to humid in West Africa. The area is currently experiencing the negative effects of rapid human population growth.Zinkina J., Andrey Korotayev, Korotayev A.]Explosive Population Growth in Tropical Africa: Crucial Omission in Development Forecasts (Emerging Risks and Way Out).
