En: The Journal of the Torrey Botanical Society Vol. 139, no. 2 (2012) 113-117Resumen: We report a detailed study of the pollen wall structure in Linum burkartii and L. usitatissimum [Linaceae]. This study was carried out using scanning electron microscopy [SEM] and transmission electron microscopy [TEM]. Results confirm that the exine of the species studied is formed by: the ectexine constituted by clavae, gemmae, and a loose basal layer, a thin endexine and a fibrilar intine. These observations constitute the first report on the ultrastructure of pollen in the Linaceae that characterizes the species here studied and expands the palynological knowledge of this family.
