Species discovery in underexplored areas
Many areas, in particular in the tropics, remain underexplored for their plant diversity and their uses. Through scientific expeditions to remote areas (mainly in sub-Saharan Africa) and through study of herbarium specimens, new species and genera to science continue to be described.
