George Bentham
George Bentham (22 September 1800 – 10 September 1884) was an English botanist, described by the weed botanist Duane Isely as "the premier systematic botanist of the nineteenth century". Born into a distinguished family, he initially studied law, but had a fascination with botany from an early age, which he soon pursued, becoming president of the Linnaean Society in 1861, and a fellow of the Royal Society in 1862. He was the author of a number of important botanical works, particularly flora. He is best known for his taxonomic classification of plants in collaboration with Joseph Dalton Hooker, his ''Genera Plantarum'' (1862–1883). He died in London in 1884. Life Bentham was born in Stoke, Plymouth, on 22 September 1800.Jean-Jacques Amigo, « Bentham (George) », in Nouveau Dictionnaire de biographies roussillonnaises, vol. 3 Sciences de la Vie et de la Terre, Perpignan, Publications de l'olivier, 2017, 915 p.

Daniel Oliver (botanist)
Daniel Oliver, FRS (6 February 1830, Newcastle upon Tyne – 21 December 1916) was an English botanist. He was Librarian of the Herbarium, Royal Botanic Gardens, Kew from 1860–1890 and Keeper there from 1864–1890, and Professor of Botany at University College, London from 1861–1888. In 1864, while at UCL, he published ''Lessons in Elementary Biology'', based upon material left in manuscript by John Stevens Henslow, and illustrated by Henslow's daughter, Anne Henslow Barnard of Cheltenham. With a second edition in 1869 and a third in 1878 this book was reprinted until at least 1891. Oliver regarded this book as suitable for use in schools and for young people remote from the classroom and laboratory. He was elected a member of the Linnean Society, awarded their Gold Medal in 1893, and awarded a Royal Medal by the Royal Society in 1884. He married in 1861 and was the father of two daughters and a son, Francis Wall Oliver. In 1895, botanist Tiegh published ''Oliverella'', ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. '' Panthera leo'' (lion) and '' Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. phylogenetic analysis should c ...

Africa
Africa is the world's second-largest and second-most populous continent, after Asia in both cases. At about 30.3 million km2 (11.7 million square miles) including adjacent islands, it covers 6% of Earth's total surface area and 20% of its land area.Sayre, April Pulley (1999), ''Africa'', Twenty-First Century Books. . With billion people as of , it accounts for about of the world's human population. Africa's population is the youngest amongst all the continents; the median age in 2012 was 19.7, when the worldwide median age was 30.4. Despite a wide range of natural resources, Africa is the least wealthy continent per capita and second-least wealthy by total wealth, behind Oceania. Scholars have attributed this to different factors including geography, climate, tribalism, Scramble for Africa, colonialism, the Cold War, neocolonialism, lack of democracy, and corruption. Despite this low concentration of wealth, recent economic expansion and the large and young ...

Asteraceae
The family Asteraceae, alternatively Compositae, consists of over 32,000 known species of flowering plants in over 1,900 genera within the order Asterales. Commonly referred to as the aster, daisy, composite, or sunflower family, Compositae were first described in the year 1740. The number of species in Asteraceae is rivaled only by the Orchidaceae, and which is the larger family is unclear as the quantity of extant species in each family is unknown. Most species of Asteraceae are annual, biennial, or perennial herbaceous plants, but there are also shrubs, vines, and trees. The family has a widespread distribution, from subpolar to tropical regions in a wide variety of habitats. Most occur in hot desert and cold or hot semi-desert climates, and they are found on every continent but Antarctica. The primary common characteristic is the existence of sometimes hundreds of tiny individual florets which are held together by protective involucres in flower heads, or more t ...

Inula
''Inula'' is a genus of about 80 species of flowering plants in the family Asteraceae, native to Europe, Asia and Africa. They may be annuals, herbaceous perennials or subshrubs that vary greatly in size, from small species a few centimeters tall to enormous perennials over tall. They carry yellow daisy-like composite flowerheads often with narrow ray-florets. Some common characteristics include pappus with bristles, flat capitulum, and lack of chaff. Several species are popular flowers for the garden, with cultivation going back to antiquity. The smaller species are used in rock gardens and the more common larger ones, which tend to have very coarse foliage, in borders. Etymology The genus name ''Inula'' is of uncertain origin, and was already in use by the Romans. The Latin phrase ''inula campana'' (field inula) gave rise to the English whose scientific name is '' Inula helenium''. The plant's specific name, ''helenium'', derives from Helen of Troy; elecampane i ...
