Erect oxalis (Latin Oxalis stricta) - a herbaceous rhizome plant of the genus Kislitsa (Latin Oxalis), reckoned to the family of the same name Kislichnye (Latin Oxalidaceae). The plant has underground stolon stems and an overground erect, branched stem covered with complex leaves. Born in North America, Kislitsa erectus successfully moved to Europe and Asia, where it is considered a stranger, but stubbornly occupies new territories. Like other species of the genus, Kislitsa erectus is quite suitable for food, if you do not overdo it with quantity, but observe the measure.
What's in your name
The meaning of the Latin name "Oxalis stricta" is quite consistent with the Russian"
Oxalis erect , Being an almost literal translation from one language to another. True, the specific epithet in Russian provides several options with the same meaning: “
Straight oxalis", or"
Sticking out oxalis ».
Straight oxalis can be easily confused with two species close to it in morphology: horned acid (Latin Oxalis corniculata) and Dilenius acid (Latin Oxalis dillenii). It is possible to distinguish Kislitsa straight from these two species by the nature of the pubescence of the stem and fruits of the plants. In the described species, the stem often does without hairs, or its hairs are multicellular and protruding, like in fruit pods. And in two competing species, the pubescence hairs are pressed against the stem or the surface of the seed capsule.
Description
Erect oxalis can be an annual or perennial plant with a thin creeping rhizome, surrounded by a network of filamentous roots, with underground stolon shoots.
In comparison with many species of the genus Kislitsa, which love to creep along the surface of the earth, the stem of Kislitsa erect reaches a height of 15 to 45 centimeters, forming compact bushes. A purplish or reddish stem is simple or branched. The surface of the stem is protected by sparse hairy pubescence.
On the stem, petiolate compound leaves are arranged in the next order. Each leaf is formed by three heart-shaped leaves, which, in unfavorable weather conditions, can fold in half along the central vein. The leaves have no stipules, and the petioles can be bare or pubescent with hairs, like the leaves themselves, ciliate along the edge.
From the axils of the leaves, long peduncles are born, crowned with semi-umbellate inflorescences. The inflorescences are formed by two to five funnel-shaped yellow flowers. There are five delicate yellow petals, as well as hairy sepals. In the pharynx of the funnel of a flower, ten yellow stamens and a polyspermous 5-celled ovary are hidden. Flowering lasts all summer months plus September.
The crown of the growing cycle is a ribbed, pubescent oblong capsule up to 2 centimeters long, filled with numerous flattened brown ovoid seeds. When a fully ripe capsule is touched, it cracks and scatters the seeds a fairly large distance around it. The seeds adhere to anything that moves and thus expand the plant's habitat.
Areal of Kislitsa upright
The birthplace of Kislitsa erect are considered to be two American continents, where she widely spread her pretty leaves and flowers.
The agile beauty has long moved to European countries with a temperate climate, and has also taken root in Western Siberia and the Far East, taking the direction to China, Korea and Japan.
Gardeners willingly cultivate an ornamental plant. Especially popular is the variety with dark red colored leaves. Oxalis erectus loves sunny places, moist, but not damp, soil. Grows on alkaline, clayey soils.
