英文摘要	Osteospermum namibense, here described as a new species, is known only from the northern part of the Namib Desert in the Kaokoveld Centre of Endemism, northwestern Namibia. Within a broad generic concept for Osteospermum (tribe Calenduleae), the new species is a member of subgen. Tripteris. These dwarf shrubs grow on rocky outcrops under harsh desert conditions. Diagnostic characters for Osteospermum namibense include the perennial, woody habit, dior trichotomous branching, succulent leaves arranged in rosettes, and capitula with 12-14 rays. A comparison of some of the more prominent morphological features to differentiate between O. namibense and its possible nearest relative, O. microcarpum (=Tripteris microcarpa), is provided. Based on IUCN Red List categories and criteria, a conservation assessment of Vulnerable (VU D1) is recommended for the new species.
