Weinmannia is a genus of trees and shrubs in the family Cunoniaceae. It contains 90 species, which range from Mexico through Central and South America including the Caribbean, and to the Mascarene Islands (Mauritius and Réunion) in the western Indian Ocean.Weinmannia L. Plants of the World Online, Kew Science. Accessed 14 April 2023. It is absent from mainland Africa and Australia, but some fossils have been attributed to Weinmannia in Australia.
Leaves are simple or pinnate, with a margin usually toothed, and interpetiolar stipules. Flowers are bisexual, white, arranged in racemes. The fruit is a capsule opening vertically from the top to the base. Seeds hairy without wings.

Unplaced names Weinmannia spiraeoides
Taxonomy Until recently the genus included five sections: Fasciculata (mostly Malesia, from Sumatra to Fiji) Inspersa (Madagascar) Leiospermum (mostly Pacific, from Bismarck archipelago to the Marquesas) Spicata (Madagascar and Comores) Weinmannia (Central and South America, Mascarenes)
A phylogenomic study by Pillon et al. (2021) concluded that Weinmannia was paraphyletic, and formed two distinct clades. The species belonging to the four Old World sections – Fasciculatae, Inspersae, Spicatae, and Leiospermum – formed a monophyletic group, which is sister to the Old World (mostly New Caledonian) genera Cunonia and Pancheria. Section Weinmannia, which includes species from the Americas and the Mascarene Islands, is sister to the Old World assemblage. They proposed placing the four Old World sections into the revived genus Pterophylla, with genus Weinmannia limited to the American and Mascarene species in section Weinmannia.Pillon, Y., H. C. F. Hopkins, O. Maurin, N. Epitawalage, J. Bradford, Z. S. Rogers, W. J. Baker, and F. Forest. 2021.
