Prostrate Hutchinsia

Hornungia procumbens (L.) Hayek

Comments

provided by eFloras
Extremely variable in plant size, indumentum, number and shape of leaf divisions, fruit shape and size, and seed number per fruit. More than 40 synonyms exist. Other synonyms probably include Lepidium chinense Stokes (Bot. Mater. Med. 3: 429. 1812), not Franchet (1883) and Nasturtium sinense (Desvaux) de Candolle (Syst. Nat. 2: 699. 1821). The latter is based on Hutchinsia sinensis Desvaux (J. Bot. Agric. 3: 168. 1815), a name proposed to replace Lepidium petraeum Loureiro (Fl. Cochinch. 2: 479. 1793), not Linnaeus (1753).

Hornungia procumbens

provided by wikipedia EN

Hornungia procumbens is a species of herb native to the temperate zone of the northern hemisphere. Common names include oval purse, slenderweed and prostrate hutchinsia.

Description

It is an annual herb with white flowers. Growth habit ranged from procumbent (trailing along the ground) to upright; when upright it can reach up to 30 centimetres in height.[1]

Taxonomy

The generic placement of this species has long been in dispute. When first published by Carl Linnaeus in his 1753 Species plantarum, it was placed in Lepidium as Lepidium procumbens. In 1815, Nicaise Auguste Desvaux transferred it into Hutchinsia. In 1832 Elias Magnus Fries transferred it into Capsella. It was transferred into Hymenolobus by Hans Schinz and Albert Thellung in 1921, and four years later placed in Hornungia by August von Hayek.[2] A number of the resulting names are still maintained. Most herbaria have adopted Hornungia procumbens, but many use Hymenolobus procumbens, and a few retain Hutchinsia procumbens.

Distribution and habitat

It is native to the temperate zone of the northern hemisphere.
