Description

Appearance and leaves

Lysiloma species grow as shrubs or trees. On the bark lenticels are recognizable. They usually have no thorns.

The alternate arranged on the branches leaves are divided into petiole and leaf blade. At the foliage leaves glands are present. The bipinnate leaf blades contain only one pair or up to 40 pairs of leaflets continuous. If many leaflets are present, they are small; if there are only a few, they are relatively large. The stalk round Blattrhachis is usually glabrous, sometimes hairy fluffy. The stipules stop beard or early deciduous.

Inflorescences and flowers

The aged men or little head shaped inflorescences are pendent together singly or in groups. The inflorescences contain durable or early falling bracts and many -stalked or sedentary flowers.

The relatively small, hermaphrodite, white to yellowish flowers are fünfzählig double perianth. The five sepals are bell-shaped fused with recognizable five calyx teeth. The five bald or hairy fluffy petals are bell-shaped fused with recognizable five Kronlappen. The stamens of 10 to 30 stamens are fused to a short Staminalröhre and they do not protrude beyond the corolla. The anthers are not hairy glandular. In each flower only one carpel is present.

Fruit and seeds

The legumes contain some seeds. The fruit flaps of most species separate from the abdominal sutures. Due to the permanent connection of two parallel seam ribs along the whole edge of Legume be Lysiloma differs from all other genera of the Ingeae in the New World. In a few species this seam ribs remain after the fruit valves are de-energized as a whole on the branch, this is called craspediale fruit opening. There is no aril available.

Occurrence

The genus Lysiloma is common only in the Neotropics. The Lysiloma species come from the southern United States via Nicaragua to Costa Rica and the Caribbean islands. Most species ranging from Mexico to Costa Rica. The most widespread species, Lysiloma latisiliquum, is also sufficient to Florida and is also found on Caribbean islands. A kind of goes back to the southeastern Arizona. One species is found only in the Greater Antilles.

Lysiloma species thrive in seasonally dry tropical and subtropical woodlands and desert vegetation on low and submontane altitudes.

Systematics and distribution of the species

The genus Lysiloma in 1844 erected by George Bentham in Journal of Botany, Volume 3, pp. 82-84. As Lectotypusart 1920 Lysiloma was bahamense Benth. Nathaniel Lord Britton established by Charles Frederick Millspaugh and in Bahama Flora, p 158; it is now a synonym of Lysiloma latisiliquum (L.) Benth .. The botanical genus name Lysiloma is derived from the Greek words lysis - for loosening or separation and loma for a border or edge. This refers to the fact that the fruit flaps of most species separate from the abdominal sutures.

Revisions of the genus in George Bentham made ​​Lysiloma: Revision of suborder Mimoseae. in Trans Linn. Soc. London, Volume 30, 1875, pp. 533-536 and in RL Thompson: A revision of the genus Lysiloma (Leguminosae ). Ph.D. Thesis, Southern Illinois University, Carbondale, 1980.

Use

Some Lysiloma species ( common name: sabicu, t'zalam, abey, feather tree ) is the wood used. The wood is used for example as a timber for the manufacture of furniture, flooring, wagon wheels and musical instruments or as firewood. Previously, the wood of Lysiloma sabicu was one of the main export products of Cuba.

Some species are used as shade trees and ornamental plants in alleys and fences. As erosion control species to be planted. There are reports of medi hiss uses.
