An undescribed species of Isoëtes (Isoëtaceae) was found during a floristic survey in Lao PDR. This Laotian species is distinctive enough to identify it as a separate species from the related taxon I. coromandelina by its megaspore characteristics, polyhedral shape, large tubercules on proximal and distal surfaces, and the uniform size. We propose I. laosiensis as a new species from South East Asia (Laos).
