description

Flower of Lagerstroemia floribunda

The lagerstroemia species are deciduous trees or shrubs . The young branches are usually square. The simple leaves are opposite or alternate, stalked or sessile, depending on the species. The leaf margins are smooth. The stipules are usually small.

The terminal inflorescences are racemose or zymös. The hermaphroditic, six-fold flowers are mostly radial symmetry , only the stamens are acyclic. The flower cup is funnel-shaped. A double perianth is formed. There are six fused sepals or they are missing. There are usually many (50 to 100), less often six to twelve, acyclically arranged, fertile stamens present. Three to six carpels are a top permanent ovary fused; with a stylus with a cephalic scar. Pollination occurs by insects ( entomophilia ). There are fruit capsules formed containing winged seeds.

distribution

The species of the genus are native to the tropical to subtropical areas of Asia and Australia . In the north, the distribution area extends to Japan .

It is used as an ornamental plant in the Mediterranean area and can also be used as a container plant. Because of its hardiness to frost, the Lagerstroemia indica can also be planted in protected areas in the wine-growing region ( USDA climate zones 7-11).

Systematics

The genus Lagerstroemia was established by Carl von Linné in 1759 . He named the genus after his friend from Sweden Magnus Lagerström (1691–1769), who was the director of the Swedish East India Company and who supplied Linnaeus with plant material.

Synonyms are: Fatioa DC. , Munchausia L.

The genus distinguishes around 50 species. Here is a selection of species:

use

Several species and their cultivars are cultivated as ornamental plants , mainly because of their flowers . Especially from the Chinese Lagerstroemia ( Lagerstroemia indica ) many forms have been bred. They are also suitable for cool winter gardens.

The very beautiful, grained and reddish-yellow, medium-weight satin wood is very popular. It is known as Pyinma.
