Karl Olov Hedberg
Prof. Karl Olov Hedberg (19 October 1923 – 24 September 2007) of Västerås was a botanist, taxonomist, author, professor of systematic botany at Uppsala University from 1970 to 1989, and an Editor of the Flora of Ethiopia. Career Professor Hedberg was a pioneer in scientific knowledge on the afroalpine vegetation. Our present knowledge of this biosystem owes much to the research he and his wife Inga did on the Rwenzori and other high mountains in East Africa. His breakthrough views were based on their systematic fieldwork in the late 1940s. 'Features of Afroalpine Plant Ecology' remains a landmark in equatorial alpine ecological research up till today, and is still available in a facsimile re-edition of 1995.Flowers of the Moon, Afroalpine vegetation of the Rwenzori Mountains

Västerås
Västerås ( , , ) is a city in central Sweden on the shore of Lake Mälaren in the province of Västmanland, west of Stockholm. The city had a population of 127,799 at the end of 2019, out of the municipal total of 154,049. Västerås is the seat of Västerås Municipality, the capital of Västmanland County and an episcopal see. History Västerås is one of the oldest cities in Sweden and Northern Europe. The name originates from ''Västra Aros'' (West Aros), which refers to the river mouth of Svartån. The area has been populated since the Nordic Viking Age, before 1000 AD. In the beginning of the 11th century it was the second largest city in Sweden, and by the 12th century had become the seat of the bishop. Anundshög is located just outside the City of Västerås. Anundshög is Sweden's largest burial mound. "Hög" is derived from the Old Norse word ''haugr'' meaning mound or barrow. It was built about 500 AD and is over wide and is almost high. In the ensuing centurie ...

Spermatophyte
The spermatophytes, also known as phanerogams (taxon Phanerogamae) or phaenogams (taxon Phaenogamae), comprise those plants that produce seeds, hence the alternative name seed plants. They are a subset of the embryophytes or land plants. The term ''phanerogams'' or ''phanerogamae'' is derived from the Greek , meaning "visible", in contrast to the cryptogamae from Greek = "hidden" together with the suffix , , "to marry". These terms distinguished those plants with hidden sexual organs (cryptogamae) from those with visible sexual organs (phanerogamae). Description The extant spermatophytes form five divisions, the first four of which are traditionally grouped as gymnosperms, plants that have unenclosed, "naked seeds": * Cycadophyta, the cycads, a subtropical and tropical group of plants, * Ginkgophyta, which includes a single living species of tree in the genus ''Ginkgo'', * Pinophyta, the conifers, which are cone-bearing trees and shrubs, and * Gnetophyta, the gnetophytes, vari ...

Senecio Hedbergii
''Senecio'' is a genus of flowering plants in the daisy family (Asteraceae) that includes ragworts and groundsels. The scientific Latin genus name, ''Senecio'', means "old man". Variously circumscribed taxonomically, the genus ''Senecio'' is one of the largest genera of flowering plants. The traditional circumscription of ''Senecio'' is artificial, being polyphyletic, even in its new circumscription which is based on genetic data. Despite the separation of many species into other genera, the genus still contains species and is one of the largest genera of flowering plants. As no morphological synapomorphies are known to determine which species belong to the genus or not, no exact species number is known. The genus has an almost worldwide distribution and evolved in the mid- to late Miocene. Some species produce natural biocides (especially alkaloids) to deter or even kill animals that would eat them. ''Senecio'' species are used as food plants by the larvae of some Lepidoptera ...

Licania Hedbergii
''Licania'' is a genus of over 200 species of trees and shrubs in the family Chrysobalanaceae. Species are found naturally occurring in Neotropical forests from southern Mexico to Brazil and the Lesser Antilles. Due to increased deforestation and loss of habitat, several species have declined, some markedly so, and ''L. caldasiana'' from Colombia appears to have gone extinct in recent years. Many species are either rare or restricted in distribution and therefore potentially threatened with future extinction. Several species are used as ornamental plants. ''Licania'' fruit are important food for many animals and can also be eaten by humans. Caterpillars of a possible new taxon of the ''Astraptes fulgerator'' cryptic species complex were found on ''L. arborea'' but do not seem to eat them regularly. Like other members of its family, the genus is known for producing a diverse array of flavonoid compounds. Selected species Species include: * ''Licania arborea'' * ''Licania calda ...

Koenigia Hedbergii
:Koenigia'' as described by Philibert Commerçon is a synonym of ''Dombeya. ''Koenigia'' is a genus of plants in the family Polygonaceae. The genus ''Aconogonon'' has been merged into ''Koenigia''. Description Species of ''Koenigia'' are annual or perennial herbaceous plants, growing from taproots. The flowers are arranged in terminal or axillary inflorescences. The flowers have pale tepals: white, greenish to yellowish white or pink. The seeds are borne in achenes that are usually brown or black in colour and not winged. Taxonomy The genus ''Koenigia'' was erected by Carl Linnaeus in 1767, initially for the type species ''Koenigia islandica''. The boundaries between genera in the family Polygonaceae, and the relationships among them, have long been a problem. At one time, many species were placed in the genus ''Polygonum''. ''Koenigia'' is placed in the subfamily Polygonoideae, tribe Persicarieae, whose taxonomic history has been described as "exceptionally convoluted, even by Po ...

Crassula Hedbergii
''Crassula'' is a genus of succulent plants containing about 200 accepted species, including the popular jade plant (''Crassula ovata''). They are members of the stonecrop family (Crassulaceae) and are native to many parts of the globe, but cultivated varieties originate almost exclusively from species from the Eastern Cape of South Africa. Crassulas are usually propagated by stem or leaf cuttings. Most cultivated forms will tolerate some small degree of frost, but extremes of cold or heat will cause them to lose foliage and die. Taxonomy ''Crassula'' was first formally described by Carl Linnaeus in 1753 with 10 species. Etymology The name crassula comes from the Latin, meaning thick, referring to the thickening of the succulent leaves. List of selected species *''Crassula alata'' *''Crassula alba'' *''Crassula alpestris'' (Sand-Coated Crassula) *''Crassula alstonii'' *''Crassula aquatica'' (common pigmyweed, water pygmyweed) *''Crassula arborescens'' (silver dollar plant, ' ...

Calamagrostis Hedbergii
''Calamagrostis'' (reed grass or smallweed) is a genus of flowering plants in the grass family Poaceae, with about 260 species that occur mainly in temperate regions of the globe. Towards equatorial latitudes, species of ''Calamagrostis'' generally occur at higher elevations. These tufted perennials usually have hairless narrow leaves. The ligules are usually blunt. The inflorescence forms a panicle. Some may be reed-like. The plants may be rhizomatous (underground stems with shoots), stoloniferous (with runners), or caespitose (growing in tufts or clumps). The bisexual spikelets have a single floret and generally they are purple or purple-brown. The spikelets are clustered into inflorescences, which usually develop in early- to mid-summer on long culms ( = stems). Many species of ''Calamagrostis'' are morphologically similar, but they generally occur in distinct habitats, and they have unique geographical distributions. Given the subtle distinctions between many closely related ...

Bryum Hedbergii
''Bryum'' is a genus of mosses in the family Bryaceae. It was considered the largest genus of mosses, in terms of the number of species (over 1000), until it was split into three separate genera in a 2005 publication. As of 2013, the classification of both ''Bryum'' and the family Bryaceae to which it belongs underwent significant changes based on DNA studies.Genus ''Bryum'', California Moss eFlora, Jepson eFlora for CA Vascular Plants, University Herbarium, University of California/ref> Description ''Bryum'' is a polyphyletic genus that has high morphological variation. Bryum species generally have shorter laminal cells with short, thick, and rounded stems. All ''Bryum'' species exhibit narrowed cells at the margins. Bryum species can be identified through patterns of asexual reproduction, coloration features of the stem and leaf base, and the strength of the leaf border. History The genus was described by Johann Hedwig in 1801, with the name being derived from the Greek word fo ...

Hedbergia
''Hedbergia'' is a monotypic genus of flowering plants, initially classified in Scrophulariaceae, and now within the broomrape family Orobanchaceae. It contains a unique species, ''Hedbergia abyssinica''. It is an afromontane genus, widespread in grasslands and scrubs of the mountains of tropical Africa, and known from Ethiopia, Zaire, Uganda, Kenya, Tanzania, Malawi, Nigeria, and Cameroons. The genus name is a taxonomic patronym honoring the Swedish botanist Karl Olov Hedberg. Description ''Hedbergia abyssinica'' is a high, very hispid perennial plant, with subsessile thick leaves, and densely crowded, white to pink or magenta flowers. Phylogeny The phylogeny of the genera of Rhinantheae has been explored using molecular characters. ''Hedbergia'' belongs to the core Rhinantheae. ''Hedbergia'' is closely related to ''Odontites'', ''Bellardia'', and ''Tozzia''. In turn, these genera share phylogenetic affinities with ''Euphrasia'', and then with ''Bartsia''. References {{ ...

Patronym (taxonomy)
A species description is a formal description of a newly discovered species, usually in the form of a scientific paper. Its purpose is to give a clear description of a new species of organism and explain how it differs from species which have been described previously or are related. The species description often contains photographs or other illustrations of the type material and states in which museums it has been deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million species have been identified and described, out of some 8.7 million that may actually exist. Millions more have become extinct throughout the existence of life on Earth. Naming process A name of a new species becomes valid (available in zoological terminology) with the date of publication of its formal scientific description. Once the scientist has performed the necessary research to determine that the discovered organism represents a ...
