Шаблон:Short description Шаблон:Speciesbox
Desmodium glabellum is a species of flowering plant in the legume family Fabaceae. It is native to the eastern and central United States. It is commonly called Dillenius' tick-trefoil in honor of Johann Dillenius, a British botanist of German birth. It is also known as the tall tick-trefoil.
Description
Desmodium glabellum is a herbaceous perennial plant. It grows to 5 feet tall with alternate palmately trifoliate leaves. Light pink to purplish flowers appear June through September. Seeds in sticky pods arranged in a row of 2-5 segments appear August–October. This species is very similar to Desmodium perplexum from which it was recently split.Шаблон:R
Taxonomy
Desmodium glabellum was first described as Hedysarum glabellum by the French botanist André Michaux in 1803.Шаблон:R The type specimen was collected in a grassland in "Lower Carolina".Шаблон:R Michaux described the stem of the species as nearly glabrous,Шаблон:Sfnp hence the specific name glabellum and the corresponding common name smooth tick-trefoil (not to be confused with Desmodium laevigatum, which also goes by that common name). In 1825, the Swiss botanist Augustin de Candolle placed Hedysarum glabellum Шаблон:Small in genus Desmodium,Шаблон:R and so Hedysarum glabellum is a basionym for Desmodium glabellum Шаблон:SmallШаблон:R
The American physician, botanist, and politician William Darlington described Desmodium dillenii in 1837.Шаблон:RШаблон:Sfnp Darlington's description was based upon an illustration of Hedysarum trifoliatum published by the German-born British botanist Johann Jacob Dillenius in 1732.Шаблон:RШаблон:Sfnp Recognizing Dillenius' contribution, Darlington referred to Desmodium dillenii as Dillenius's Desmodium. In 1950, the American botanist Bernice Schubert rejected Desmodium dillenii Шаблон:Small as a nomen confusum (a term having no standing in the International Code of Nomenclature of 2018),Шаблон:Sfnp which means "confusing name". In an attempt to resolve the confusion, Schubert split the taxon into two distinct taxa, a newly described Desmodium perplexum,Шаблон:R and the previously described Desmodium glabellum. However, Schubert did not identify the plant in Dillenius' illustration. The matter remained unresolved until 2020 when the morphologies of the taxa in question were sufficiently clarified.Шаблон:Sfnp Subsequently the plant in Dillenius' illustration was identified as Desmodium glabellum,Шаблон:Sfnp and hence the name Desmodium dillenii Шаблон:Small is a synonym for Desmodium glabellum Шаблон:SmallШаблон:R The common name Dillenius' tick-trefoil is often used to refer to Desmodium glabellum.Шаблон:R
Desmodium glabellum is a member of the Desmodium paniculatum complex, a group of closely related taxa that also includes Desmodium paniculatum sensu stricto, Desmodium perplexum, Desmodium fernaldii, and the synonym Desmodium dillenii.Шаблон:Sfnp Alternatively, some botanists lump these taxa into a single polymorphic species, Desmodium paniculatum sensu lato,Шаблон:R in which case Desmodium glabellum becomes a synonym of Desmodium paniculatum.
Distribution and habitat
Desmodium glabellum is native to the eastern and central United States.Шаблон:R It grows in fields, woodland borders, and disturbed areas.Шаблон:R
