摘要

The German botanist Gustav Albert Peter is known for his extensive botanical work in South and East Africa. As a result of these expeditions, Peter described eleven species of Portulaca from present-day Tanzania in his Flora von Deutsch-Ostafrika. Many of these names lack typification or have ambiguous type designations. In this study, we review the protologues and original material housed at the B herbarium related to Tanzanian Portulaca names proposed by Peter. We designate five lectotypes and two second-step lectotypes following the rules of the International Code of Nomenclature.
