Paul Fryxell
Paul Arnold Fryxell was an American botanist known for his work on flowering plants, especially those within the Malvaceae. Education and career Fryxell attended Moline public schools and later Augustana College, graduating with a B.A. in 1949, and Iowa State University (M.S., 1951, Ph.D., 1955). After employment with the New Mexico Agricultural Experiment Station (1952–1955) and the Wichita State University (Asst. Professor of Botany, 1955–1957), he joined the Agricultural Research Service, USDA, with which agency he spent most of his career as a Research Botanist, located on the Texas A&M University campus. He retired from this position in 1994 and became Adjunct Professor in Integrative Biology at the University of Texas at Austin. He was also an Honorary Curator at the New York Botanical Garden. Research His research interests have centered on the taxonomy of the Neotropical Malvaceae, including work on the evolution, biodiversity, and taxonomy of Gossypium, the ...

Lyndley Craven
Lyndley Alan Craven (3 September 1945 – 11 July 2014) was a botanist who became the Principal Research Scientist of the Australian National Herbarium. Lyndley ("Lyn") Craven worked for the CSIRO plant taxonomy unit of the New Guinea Survey Group, Division of Land Research and Regional Survey from 1964 to 1967.

Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. The term "angiosperm" is derived from the Greek words ('container, vessel') and ('seed'), and refers to those plants that produce their seeds enclosed within a fruit. They are by far the most diverse group of land plants with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species. Angiosperms were formerly called Magnoliophyta (). Like gymnosperms, angiosperms are seed-producing plants. They are distinguished from gymnosperms by characteristics including flowers, endosperm within their seeds, and the production of fruits that contain the seeds. The ancestors of flowering plants diverged from the common ancestor of all living gymnosperms before the end of the Carboniferous, over 300 million years ago. The closest fossil relatives of flowering plants are uncertain and contentious. The earliest angiosperm fossils ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Malva
''Malva'' is a genus of herbaceous annual, biennial, and perennial plants in the family Malvaceae. It is one of several closely related genera in the family to bear the common English name mallow. The genus is widespread throughout the temperate, subtropical and tropical regions of Africa, Asia and Europe. The leaves are alternate, palmately lobed. The flowers are from 0.5–5 cm diameter, with five pink, lilac, purple or white petals. Etymology The word "mallow" is derived from Old English "mealwe", which was imported from Latin "malva", cognate with Ancient Greek μαλάχη (malakhē) meaning "mallow", both perhaps reflecting a Mediterranean term. The colour mauve was in 1859 named after the French name for this plant. Uses Ornamental plant Several species are widely grown as garden flowers. Very easily grown, short-lived perennials are often grown as ornamental plants. Food Many species are edible as leaf vegetables and commonly foraged in the West. Known as ...

Malvaceae
Malvaceae, or the mallows, is a family of flowering plants estimated to contain 244 genera with 4225 known species. Well-known members of economic importance include okra, cotton, cacao and durian. There are also some genera containing familiar ornamentals, such as ''Alcea'' (hollyhock), ''Malva'' (mallow), and ''Tilia'' (lime or linden tree). The largest genera in terms of number of species include ''Hibiscus'' (300 species), ''Sterculia'' (250 species), ''Dombeya'' (250 species), '' Pavonia'' (200 species) and '' Sida'' (200 species). Taxonomy and nomenclature The circumscription of the Malvaceae is controversial. The traditional Malvaceae '' sensu stricto'' comprise a very homogeneous and cladistically monophyletic group. Another major circumscription, Malvaceae ''sensu lato'', has been more recently defined on the basis that genetics studies have shown the commonly recognised families Bombacaceae, Tiliaceae, and Sterculiaceae, which have always been considered closely allie ...

Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northern Territory
The Northern Territory (commonly abbreviated as NT; formally the Northern Territory of Australia) is an states and territories of Australia, Australian territory in the central and central northern regions of Australia.

Australian Plant Name Index
The Australian Plant Name Index (APNI) is an online database of all published names of Australian vascular plants. It covers all names, whether current names, synonyms or invalid names. It includes bibliographic and typification details, information from the Australian Plant Census including distribution by state, links to other resources such as specimen collection maps and plant photographs, and the facility for notes and comments on other aspects. History Originally the brainchild of Nancy Tyson Burbidge, it began as a four-volume printed work consisting of 3,055 pages, and containing over 60,000 plant names. Compiled by Arthur Chapman, it was part of the Australian Biological Resources Study (ABRS). In 1991 it was made available as an online database, and handed over to the Australian National Botanic Gardens. Two years later, responsibility for its maintenance was given to the newly formed Centre for Plant Biodiversity Research. Scope Recognised by Australian herbaria as the ...

Hibiscus
''Hibiscus'' is a genus of flowering plants in the mallow family, Malvaceae. The genus is quite large, comprising several hundred species that are native to warm temperate, subtropical and tropical regions throughout the world. Member species are renowned for their large, showy flowers and those species are commonly known simply as "hibiscus", or less widely known as rose mallow. Other names include hardy hibiscus, rose of sharon, and tropical hibiscus. The genus includes both annual and perennial herbaceous plants, as well as woody shrubs and small trees. The generic name is derived from the Greek name ἰβίσκος (''ibískos'') which Pedanius Dioscorides gave to ''Althaea officinalis'' ( 40–90 AD). Several species are widely cultivated as ornamental plants, notably ''Hibiscus syriacus'' and ''Hibiscus rosa-sinensis''. A tea made from hibiscus flowers is known by many names around the world and is served both hot and cold. The beverage is known for its red colour, t ...
