Lithospermum sylvestre (Boraginaceae): A new species from the Baviaanskloof, Eastern Cape, South Africa

Abstract

Background: Recent field work in the Baviaanskloof, Eastern Cape, resulted in several collections of an unknown species of Lithospermum (Boraginaceae), a genus that is taxonomically relatively poorly understood in southern Africa. Objectives: To describe the Baviaanskloof collections and characterise them against currently known species of Lithospermum. Method: Relevant literature was surveyed and herbarium and fresh material was examined. Results: Recent collections of Lithospermum from the Baviaanskloof Mountains in Eastern Cape represent an undescribed species. Conclusion: Lithospermum sylvestre J.Cohen J.C.Manning is a new species recognised by its well-branched stems with adpressed-scabrid pubescence, and relatively long-tubed flowers with long styles that are ± as long as the corolla tube and only shortly included within it.
