description

Vegetative characteristics

Dichrostachys cinerea grows as a fast-growing, thorny and deciduous shrub or small tree and reaches heights of 1.5 to 6, rarely up to 12 meters. The branches have individual thorns 7–8 centimeters long. The gray-brown to gray, thick bark is furrowed.

The stalked and alternate leaves are bipinnate and up to 3–8 inches long. The petiole is up to 5–6 millimeters long. There are many (up to 19 pairs) pinnate with many (up to 41 pairs) very small leaflets . The rachis, the leaflets and the petiole are more or less hairy, on the rachis glands can occur. The entire-edged leaflets are only 1.5–12 millimeters long. There are small stipules present.

Generative characteristics

The conspicuous, two-colored and pendulous, axillary, small- eared inflorescences get their characteristic color from the pink, purple to white staminodes without anthers of the sterile flowers or the hermaphrodite flowers in the lower part with the mostly yellow stamens . The small, fragrant and sessile flowers are hermaphroditic and five-fold with a double flower envelope . The petals are greenish-white-pink or yellowish. There are 10 slightly protruding stamens, sometimes with a falling gland at the anthers, and a top permanent, weichaariger ovary with a long stylus with capitate, flat scar present.

The dark brown, in several, balled-up, mostly twisted, twisted and mostly non-opening, hard-leather and more or less finely haired legumes have a length of 4 to 9 centimeters and a diameter of 0.6 to 1.5 centimeters. The 4–6 brown to blackish, smooth, somewhat shiny and flat seeds with pleurogram are about 4–5 millimeters long.

Occurrence

It thrives in the sandy soils of the West African coastal areas and the savannah in tropical and southern Africa as far as India and Southeast Asia . As an invasive plant , for example in Cuba (called “Marabú” there), Dichrostachys cinerea is considered to be difficult to control “ untreated willow ” and is widespread.

Taxonomy

It was first published under the name ( Basionym ) Mimosa cinerea in 1753 by Carl von Linné . The new combination to Dichrostachys cinerea was published in 1834 by Robert Wight and George Arnott Walker Arnott .

The generic name Dichrostachys ( Greek ) means "two-colored ear". The specific epithet cinerea is derived from the Latin word cineres for "ash gray".

Further synonyms for Dichrostachys cinerea (L.) Wight & Arn. of many are: Cailliea glomerata (Forssk.) JFMacbr. , Dichrostachys glomerata (Forssk.) Chiov. , Desmanthus leptostachys DC. and Dichrostachys nutans (Pers.) Benth. or Mimosa glomerata Forssk.

Different subspecies and varieties are distinguished.

use

The high-density wood of the color kitten bush is used as fuel and can be processed into high-quality, slow-burning charcoal .
