A revision of the genera Alysicarpus Desv. and Desmodium Desv. (Desmodieae: Desmodiinae) for the Mexican region of the Yucatán Peninsula is presented. This treatment is based on the study of botanical material of 8 herbaria, CHAPA, CICY, CIQRO, ENCB, IEB, MEXU, UCAM, and XAL. We recognized Alysicarpus vaginalis (L.) DC., Desmodium affine Schltdl., D. distortum (Aubl.) J.F. Macbr., D. glabrum (Mill.) DC., D. incanum DC., D. procumbens (Mill.) Hitchc., D. scorpiurus (Sw.) Desv., D. tortuosum (Sw.) DC., and D. triflorum (L.) DC. Identification keys to genera and to species are included, as well as morphological descriptions, ecology, phenology, some common names and uses for each species.
