SOUTH AFRICAN JOURNAL OF BOTANY(2023)
Abstract
A taxonomic revision of the Gnidia linearifolia group (Thymelaeaceae: Thymelaeoideae) is presented. Species in this group are diagnosed by punctate leaves that are ciliate when young, a densely hairy hypanthium, and petaloid scales with a basal callus. We recognize five species: G. linearifolia (Wikstr.) B.Peterson, G. nana (L.f.) Wikstr., G. penicillata Licht. ex Meisn., G. scabrida Meisn. and G. tomentosa L. This account includes descriptions, complete nomenclature and typification, illustrations, geographical distribution, and a key to the species. A lectotype is designated for Gnidia scabrida and Gnidia penicillata. (c) 2023 The Authors. Published by Elsevier B.V. on behalf of SAAB.
