Abstract:As a result of recent fieldwork in north-east Morocco, a new woody Malvaceae species, Lavatera valdesii Molero & J.M. Monts., is described here. The morphological characters that link it to other species in Sect. Olbia (Medik.) DC. are discussed, as are those traditionally used in defining the species that make up this section. A recently described species of this group, Lavatera plazzae Atzei, is established here as a synonym of L. stenopetala Coss. & Durieu ex Batt., a species previously considered as an endemic of east Algeria. On the basis of morphological characters, we propose the exclusion of both L. thuringiaca and L. cashmiriana Cambess. from Sect. Olbia.  © 2007 The Linnean Society of London, Botanical Journal of the Linnean Society , 2007, 153 , 445–454.
