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. Schutyser S. ...

Västerås
Västerås ( , , ) is a city in central Sweden on the shore of Mälaren, 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 CE. 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 CE and is over wide and is almost high. In the ensu ...

Spermatophyte
A spermatophyte (; ), also known as phanerogam (taxon Phanerogamae) or phaenogam (taxon Phaenogamae), is any plant that produces seeds, hence the alternative name seed plant. Spermatophytes are a subset of the embryophytes or land plants. They include most familiar types of plants, including all flowers and most trees, but exclude some other types of plants such as ferns, mosses, algae. The term ''phanerogams'' or ''phanerogamae'' is derived from the Greek (), meaning "visible", in contrast to the cryptogamae (), together with the suffix (), meaning "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 s ...

Senecio Hedbergii
''Senecio'' is a genus of flowering plants in the daisy family (Asteraceae) that includes ragworts and groundsels. Variously circumscribed taxonomically, the genus ''Senecio'' is one of the largest genera of flowering plants. Description Morphology The flower heads are normally rayed with the heads borne in branched clusters, and usually completely yellow, but green, purple, white and blue flowers are known as well. In its current circumscription, the genus contains species that are annual or perennial herbs, shrubs, small trees, aquatics or climbers. The only species which are trees are the species formerly belonging to '' Robinsonia'' occurring on the Juan Fernández Islands. Chemistry Pyrrolizidine alkaloids are found in all ''Senecio'' species. These alkaloids serve as a natural biocides to deter or even kill animals that would eat them. Livestock generally do not find them palatable. ''Senecio'' species are used as food plants by the larvae of some Lepidoptera specie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 ...

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 adjective ''crassus'', 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 arbore ...

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 rela ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
