Loasoideae
Loasaceae is a family of 15–20 genera and about 200–260 species of flowering plants in the order Cornales, native to the Americas and Africa. Members of the family include annual, biennial and perennial herbaceous plants, and a few shrubs and small trees. Members of the subfamily Loasoideae are known to exhibit rapid thigmonastic stamen movement when pollinators are present. Taxonomy In the classification system of Dahlgren the Loasaceae were placed in the order Loasales in the superorder Loasiflorae (also called Loasanae). The Angiosperm Phylogeny Group system places them in the related order Cornales in the asterid clade. Genera 21 genera are accepted:Loasaceae Juss. '' |
Thigmonasty
In biology, thigmonasty or seismonasty is the nastic movement, nastic (non-directional) response of a plant or fungus to touch or vibration. Conspicuous examples of thigmonasty include many species in the Fabaceae, leguminous family (biology), subfamily Mimosoideae, active carnivorous plants such as ''Dionaea (plant), Dionaea'' and a wide range of pollination mechanisms. Distinctive aspects Thigmonasty differs from thigmotropism in that nastic motion is independent of the direction of the stimulus. For example, tendrils from a climbing plant are thigmotropic because they twine around any support they touch, responding in whichever direction the stimulus came from. However, the shutting of a venus fly trap is thigmonastic; no matter what the direction of the stimulus, the trap simply shuts (and later possibly opens). The time scales of thigmonastic responses tend to be shorter than those of thigmotropic movements because many examples of thigmonasty depend on pre-accumulated turg ...

Grausa
''Grausa'' is a genus of plants in the Loasaceae found in Chile and Argentina. It was previously included in the genus '' Loasa'' and was split to resolve a paraphyletic grouping of genera in the Loasaceae. The seeds of this genus have a characteristic hilar cone. Description ''Grausa'' is a small genus of perennial herbs. Species generally assume one of two vegetative habits, either rhizomatous with short internodes or climbing with winding aerial stems. The petiolate leaves are arranged in a basal rosette. Leaf shape ranges from sagittate to pinnatisect to ternately compound and rarely pinnate. The leaves are covered in rough trichomes with few or no stinging hairs. The inflorescences of ''Grausa'' species are axillary and may be one-flowered or branching and winding with multiple flowers. The bracts are pinnatisect or palmatisect. The flowers are borne on pedicels; those on one-flowered rhizomatous species are erect, whereas those on winding multi-flowered species are pendent ...

Rolf Dahlgren
Rolf Martin Theodor Dahlgren (7 July 1932 – 14 February 1987) was a Swedish- Danish botanist and professor at the University of Copenhagen from 1973 to his death. Life Dahlgren was born in Örebro on 7 July 1932 to apothecary Rudolf Dahlgren and wife Greta née Dahlstrand. He took his MSc degree in Biology in (1955) and PhD degree in Botany in (1963) at Lund University. He was killed in a car crash in Scania, Sweden on 14 February 1987. Career He continued working on South African plants during expeditions in 1956-57 and 1965–66, while affiliated with the ''Botanical Museum'' in Lund as '' docent''. In 1973, he became professor of botany at the University of Copenhagen. Here, he developed his system of Angiosperm classification, based on many more characters simultaneously than previous systems, most notably many chemical plant traits (see also chemotaxonomy). Although the system was first presented in Danish, it rapidly gained widespread acceptance, particularly due ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Plants Of The World Online
Plants of the World Online (POWO) is an online taxonomic database published by the Royal Botanic Gardens, Kew. History Following the Convention on Biological Diversity, the Royal Botanic Gardens in Kew launched Plants of the World Online in March 2017 with the goal of creating an exhaustive online database of all seed-bearing plants worldwide. (Govaerts wrongly speaks of "Convention for Botanical Diversity (CBD)). The initial focus was on tropical African flora, particularly flora ''Zambesiaca'', flora of West and East Tropical Africa. Since March 2024, the website has displayed AI-generated predictions of the extinction risk for each plant. Description The database uses the same taxonomical source as the International Plant Names Index, which is the World Checklist of Vascular Plants (WCVP). The database contains information on the world's flora gathered from 250 years of botanical research. It aims to make available data from projects that no longer have an online ...

Clade
In biology, a clade (), also known as a Monophyly, monophyletic group or natural group, is a group of organisms that is composed of a common ancestor and all of its descendants. Clades are the fundamental unit of cladistics, a modern approach to taxonomy adopted by most biological fields. The common ancestor may be an individual, a population, or a species (extinct or Extant taxon, extant). Clades are nested, one in another, as each branch in turn splits into smaller branches. These splits reflect evolutionary history as populations diverged and evolved independently. Clades are termed ''monophyletic'' (Greek: "one clan") groups. Over the last few decades, the cladistic approach has revolutionized biological classification and revealed surprising evolutionary relationships among organisms. Increasingly, taxonomists try to avoid naming Taxon, taxa that are not clades; that is, taxa that are not Monophyly, monophyletic. Some of the relationships between organisms that the molecul ...
