Summary
Pinter M., Martínez-Azorín M., Crespo M. B., Alonso-Vargas M. Á. & Wetschnig W. 2019. Striatula (Hyacinthaceae, Urgineoideae), a new genus from South Africa and southern Namibia. – Phyton (Horn, Austria) 59 (1–2): 91–98, with 1 figure and 1 table.*
Within the framework of the taxonomic revision of subfamily Urgineoideae of Hyacinthaceae, we here describe the new genus Striatula from South Africa and southern Namibia. Striatula is at first sight related to Rhadamanthus species, but can be easily distinguished by the one or two flat, ovate to elliptic, sulcate leaves which are appressed to the ground. This genus includes Rhadamanthus platyphyllus, a species native to the Western, Eastern and Northern Cape Province of South Africa, and the more recently described Drimia oliverorum from Namibia. A morphological description for Striatula is presented, including the most important characteristics and the necessary new combinations.
