A series of crosses was performed to investigate relationships between 7 taxa of the genus Coincya Rouy: C. hispida var. hispida, C. hispida var. deflexa, C. leptocarpa f. leptocarpa, C. leptocarpa f. calatrava, C. longirostra, C.pseudoerucastrum subsp. pseudoerucastrum and C. pseudoerucastrum subsp. cintrana. Several viable seeds were obtained from the hybrid crosses performed and the number of seeds per pollinated flower was counted for each cross. Pollen fertility was determined in 18 of the crosses, and the stability of meiosis was estimated in some of the F l hybrids. Fruit morphology and seed production in 9 of the crosses was compared to those of the parents. Data corresponding to interfertility, pollen fertility and fruit morphology were used to draw taxonomic conc\usions.
