Craibia is a genus of flowering plants in the legume family Fabaceae (order Fabales, class Magnoliopsida). Nine species are currently accepted within the genus. It is native to sub-Saharan Africa, with a distribution extending from Liberia in West Africa east to the Horn of Africa and south to the Cape Provinces of South Africa, spanning a broad range of tropical and subtropical African habitats.
The genus was published in 1911, in the Journal of Botany (volume 49, page 106). GBIF's taxonomic backbone credits the authorship jointly to Harms and Dunn, while other sources attribute the publication to British botanist Stephen Troyte Dunn alone. The genus name honors William Grant Craib (1882–1933), a British botanist who worked as an Assistant for India at the Royal Botanic Gardens, Kew, and later became a professor at the University of Aberdeen. Craib is best remembered for his contributions to Southeast Asian botany, notably Contributions to the Flora of Siam (1912) and Florae Siamensis Enumeratio (1925).
The nine accepted species are Craibia affinis, C. atlantica, C. brevicaudata, C. brownii, C. grandiflora, C. laurentii, C. lujae, C. simplex, and C. zimmermannii. GBIF's backbone additionally lists 19 taxon records (species and synonyms) nested beneath the genus, reflecting a history of taxonomic revision within the group. As a member of Fabaceae, Craibia belongs to a family widely known for nitrogen-fixing, woody and herbaceous species distributed across tropical and temperate regions worldwide.
