Bulbine dewetii, a New Cliff-Dwelling Bulbine Species (Asphodelaceae) from the Western Cape

Abstract

Abstract: Bulbine dewetii (Asphodelaceae) is named; it is an obligatory geophytic cremnophyte from the sheer rock faces of the lower southern slopes of the Heks River Mountains (Western Cape, South Africa). Bulbine dewetii usually grows solitary (rarely proliferating and forming small groups) with soft pendent leaves, flowering during the month of November (late spring, S. Hemisphere), the flowers open during the afternoon and remain open during the night. The description of this taxon forms part of an extensive survey of cliff-dwelling succulent and bulbous-succulent taxa in South Africa and Namibia.
