Asteranthe Asterias
'' Asteranthe asterias'' is a species of plant in the family Annonaceae. It is native to Kenya and Tanzania. Spencer Le Marchant Moore, the English botanist who first formally described the species using the basionym ''Uvaria asterias'', did not explicitly explain the epithet, but was likely referencing the star-like appearance of its flower’s petals. Description It is a tree reaching 1.5 to 8 meters in height. Its young branches are covered in dense grey or rust colored hairs. Its mature branches are hairless and have lenticels. Its oval to oblong leaves are 4-16.5 by 2-6 centimeters and come to a tapering point at their tips. The leaves are hairless and sometimes shiny on their upper surface, while their lower surface is densely hairy when young, but when mature hairless. Its petioles are 2-7 millimeters long. Its fragrant, hermaphroditic flowers are on 3-8 millimeter long pedicels that have oval, hairy bracteoles that are 2.5-4 by 1-1.5 millimeters. Its sepals a ...

Asteranthe Lutea
''Asteranthe lutea'' is a species of plant in the genus ''Asteranthe''. It is native to Tanzania. Kaj Borge Vollesen, the botanist who first formally described the species in 1980, named it after its yellow ( in Latin) petals. Description It is a bush reaching 4 meters in height. Its elliptical leaves are 7-18.5 by 2.7-9 centimeters. The bases of the leaves are rounded or notched at the point of attachment to the petioles. The tips of the leaves come to a short tapered tip. The leaves have 10-15 pairs of secondary veins emanating from their midribs. Its petioles are 3-5 millimeters long and covered in dense woolly hairs. Its solitary, fragrant flowers are on 2-8 millimeter long pedicels that occur at extra- axillary or terminal positions. Its pedicels are covered in dense white woolly hairs and have an oval, green bracteole that is 6-8 by 5-7 millimeters. The bracteoles have a notched base and come to point at their tip. Its green, oval sepals are 1-1.5 by 0.8-1.2 centimet ...

Adolf Engler
Heinrich Gustav Adolf Engler (25 March 1844 – 10 October 1930) was a German botanist. He is notable for his work on alpha taxonomy, plant taxonomy and phytogeography, such as ''Die natürlichen Pflanzenfamilien'' (''The Natural Plant Families''), edited with Karl Anton Eugen Prantl, Karl A. E. von Prantl. Even now, his system of plant classification, the Engler system, is still used by many Herbarium, herbaria and is followed by writers of many manuals and Flora (plants), floras. It is still the only system that treats all 'plants' (in the wider sense, algae to flowering plants) in such depth. Engler published a prodigious number of taxonomic works. He used various artists to illustrate his books, notably Joseph Pohl (1864–1939), an illustrator who had served an apprenticeship as a wood-engraver. Pohl's skill drew Engler's attention, starting a collaboration of some 40 years. Pohl produced more than 33 000 drawings in 6 000 plates for ''Die naturlichen Pflanzenfamilien''. He ...

Ludwig Diels
Dr. Friedrich Ludwig Emil Diels (24 September 1874 – 30 November 1945) was a German botanist. Diels was born in Hamburg, the son of the classical scholar Hermann Alexander Diels. From 1900 to 1902 he traveled together with Ernst Georg Pritzel through South Africa, Java, Australia and New Zealand. Shortly before the First World War he travelled New Guinea and in the 1930s in Ecuador. Especially his collections of plants from Australia and Ecuador, which contained numerous holotypes, enriched the knowledge of the concerning floras. His monography on the Droseraceae from 1906 is still a standard. The majority of his collections were stored at the botanical garden in Berlin-Dahlem, whose vicedirector he had been since 1913, becoming its director in 1921 until 1945. His collections were destroyed there during an air raid in 1943. He died in Berlin on 30 November 1945. Honours Several genus of plants have been named after him including; ''Dielsantha'' (from ''Campanulaceae' ...

Plants
Plants are predominantly Photosynthesis, photosynthetic eukaryotes of the Kingdom (biology), kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyte, Glaucophyta, and consists of the green algae and Embryophyte, Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and Fern ally, their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green colo ...

Annonaceae
The Annonaceae are a Family (biology), family of flowering plants consisting of trees, shrubs, or rarely lianas commonly known as the custard apple family or soursop family. With 108 accepted genera and about 2400 known species, it is the largest family in the Magnoliales. Several genera produce edible fruit, most notably ''Annona'', ''Anonidium'', ''Asimina'', ''Rollinia'', and ''Uvaria''. Its type genus is ''Annona''. The family is concentrated in the tropics, with few species found in temperate regions. About 900 species are Neotropical, 450 are Afrotropical, and the remaining are Indomalayan. Description The species are mostly tropical, some are mid-latitude, deciduous or evergreen trees and shrubs, with some lianas, with aromatic bark, leaves, and flowers. ; Stems, stalks and leaves: Bark is fibrous and aromatic. Pith septate (fine tangential bands divided by partitions) to diaphragmed (divided by thin partitions with openings in them). Branching distichous (arranged in two ...

Tanzania
Tanzania (; ), officially the United Republic of Tanzania ( sw, Jamhuri ya Muungano wa Tanzania), is a country in East Africa within the African Great Lakes region. It borders Uganda to the north; Kenya to the northeast; Comoro Islands and the Indian Ocean to the east; Mozambique and Malawi to the south; Zambia to the southwest; and Rwanda, Burundi, and the Democratic Republic of the Congo to the west. Mount Kilimanjaro, Africa's highest mountain, is in northeastern Tanzania. According to the United Nations, Tanzania has a population of million, making it the most populous country located entirely south of the equator. Many important hominid fossils have been found in Tanzania, such as 6-million-year-old Pliocene hominid fossils. The genus Australopithecus ranged across Africa between 4 and 2 million years ago, and the oldest remains of the genus ''Homo'' are found near Lake Olduvai. Following the rise of '' Homo erectus'' 1.8 million years ago, humanity spread ...

Hermaphrodite
In reproductive biology, a hermaphrodite () is an organism that has both kinds of reproductive organs and can produce both gametes associated with male and female sexes. Many Taxonomy (biology), taxonomic groups of animals (mostly invertebrates) do not have separate sexes. In these groups, hermaphroditism is a normal condition, enabling a form of sexual reproduction in which either partner can act as the female or male. For example, the great majority of tunicata, tunicates, pulmonate molluscs, opisthobranch, earthworms, and slugs are hermaphrodites. Hermaphroditism is also found in some fish species and to a lesser degree in other vertebrates. Most plants are also hermaphrodites. Animal species having different sexes, male and female, are called Gonochorism, gonochoric, which is the opposite of hermaphrodite. There are also species where hermaphrodites exist alongside males (called androdioecy) or alongside females (called gynodioecy), or all three exist in the same species ( ...
