Dombeya acutangula, the bois bete or mahot tantan, is a species of flowering plant in the family Malvaceae.

It is native to the Mascarene Islands (Mauritius, Réunion, and Rodrigues), and Madagascar, Malawi, Mozambique, Tanzania, and Zambia.

[2] It has charming pale (white or light pink) flowers in small clusters.

It is almost extinct on the island due to habitat loss; some 50 plants remain in the wild, growing in a narrowly circumscribed area at Corps de garde, Trois Mamelles, Yemen, Magenta and Chamarel.

It is somewhat variable and thus was described under a number of names, which are now considered junior synonyms:[4] This species is rather isolated among its congeners and may belong to the more basal members of its genus.
