The aim of the study is to provide a revision of the genus in southern Africa. The genus is taxonomically problematic within the family Boraginaceae, due to the morphological similarities it shares with other closely related genera in the family. plants are low-growing biennial, perennial, or rarely annual herbs which are recognizable by their hairy stems and leaves, the latter are usually basal and long petiolate. Based on the latest checklist, a total of eight species of this genus are listed for the study region: , , , , , , (endemic to South Africa), and . The occurrence of in the region, however, requires further investigation since the only existing specimen was collected within a protected area in the KwaZulu-Natal province. Two specimens collected in the Doornpoort area in Pretoria, Gauteng province, assigned to this species appear to have been misidentified. Diagnostic characters are described, correct nomenclature, synonyms, typification, distribution maps, as well as the key for identifying the studied species, are provided.
本研究的目的是对南部非洲的该属植物进行修订。由于该属植物与紫草科中其他近缘属存在形态相似性，因此在分类学上存在问题。该属植物为低矮的二年生、多年生或极少为一年生草本，其茎和叶具毛，后者通常基生且具长叶柄，据此可识别。根据最新的名录，该研究区域共列出该属的8个物种：[物种名1]、[物种名2]、[物种名3]、[物种名4]、[物种名5]、[物种名6]、[物种名7]（南非特有）和[物种名8]。然而，该属植物在该区域的出现情况需要进一步调查，因为现存的唯一标本是在夸祖鲁 - 纳塔尔省的一个保护区内采集的。在豪登省比勒陀利亚的杜恩普特地区采集的两份被归为此物种的标本似乎被误认了。文中描述了诊断特征，并提供了正确的命名法、同义词、模式指定、分布图以及识别所研究物种的检索表。
