Cordia is a genus of flowering plants in the borage family, Boraginaceae. It contains about 300 species of shrubs and trees, that are found worldwide, mostly in warmer regions. Many of the species are commonly called manjack, while bocote may refer to several Central American species in Spanish. The generic name honours German botanist and pharmacist Valerius Cordus (1515-1544). Like most other Boraginaceae, the majority have trichomes (hairs) on the leaves.
