Dichrostachys cinerea, known as sicklebush, Bell mimosa, Chinese lantern tree or Kalahari Christmas tree (South Africa), is a legume of the genus Dichrostachys in the Fabaceae family.
Other common names include acacia Saint Domingue (French), el marabu (Cuba), " Mpangara" (Shona), Kalahari-Weihnachtsbaum (German of former South West Africa), kéké or mimosa clochette (Réunion).
The generic name Dichrostachys means 'two-colored spike', referring to its two-colored inflorescence, from the Ancient Greek δί- (di-, 'twice'), χροός (khroos, 'color'), and στάχυς (stakhus, 'ear of grain'). The specific name cinerea refers to the greyish hairs of the typical subspecies, from the Latin cinereus ('ashes').
It is native to Africa but has been introduced to India, the Caribbean and parts of Southeast Asia. In Ethiopia, the species is common in the Nechisar National Park.
The tree was brought to the Caribbean in the 19th century. In Cuba, where it is known as El Marabú or Marabou weed, it has become a serious invasive species problem, occupying close to five million acres (20,000 km²) of agricultural land. Plans are underway to exploit it as a source of biomass for renewable power generation.
Dichrostachys cinerea is a semi-deciduous to deciduous tree characterized by bark on young branches, dark grey-brown fissures on older branches and stems and smooth on the spines. They typically grow up to 7 metres (23 ft) in height and have strong alternate thorns, generally up to 8 cm (3.1 in) long. Flowers of the Dichrostachys cinerea are characteristically in bicoloured cylindrical spikes that resemble Chinese lanterns and are 6–8 cm long and fragrant. Upper flowers of a hanging spike are sterile, and are of a lilac or pale purple. Pods are usually a mustard brown and are generally twisted or spiralled and may be up to 100 × 15 mm. The species can be subcategorized with two slight variations that have been recognised: D. cinerea ssp. africana and D. cinerea ssp. nyassana, the latter which is typically larger and less hairy in its foliage.
