Only one species, <strong>L. suffruticosum<\/strong>, has clearly woody stems, at least at the base, and is often some 0.5 m in height. The other species of the genus in the region, \u00b1 woody but less robust, are subshrubs with alternate leaves and pentamerous flowers.<\/p>\n<p><strong> L. narbonense <\/strong>L. (<em>Ara<\/em>. Egypt: Orq-angebar), lignified at the base and sometimes exceeding 0.5m in height (especially when growing amongst dense vegetation) is easily differentiated from the former by its flat leaves, with margin only slightly or not revolute at all and flowers with blue petals 20-30(40) mm. It grows on calcareous soils of the western Mediterranean, in North Africa it lives in N Morocco and N Algeria.<\/p>\n<p><strong> L. grandiflorum<\/strong> Desf. is a rare subshrub with lanceolate leaves, easy to differentiate by its solitary flowers with large petals (<em>c. <\/em>30 mm.) reddish with black vernation, and capsule 8-10 mm. Endemic to the littoral regions of NE Morocco and NW Algeria; the citations from Tunisia appear to be from cultivated specimens.<\/p>\n<p><strong> L. numidicum<\/strong> Murb. differs clearly by having flowers in groups with yellowish or whitish-yellowish petals (15-24 mm), and capsules 4-5 mm. Generally on siliceous soils in subhumid and humid environments in northern parts of Morocco, Algeria and Tunisia.<\/p>\n<p>Relatively common species, none are considered threatened. Currently, they have not been assessed at a global level on the <em>IUCN Red List of Threatened Species<\/em>. In the Livre Rouge de la flore vasculaire du Maroc (Fennane, 2021) <em>L. narbonense<\/em> has been considered as Endangered (EN).
