Nomenclatural revision of Portulaca names (Portulacaceae) published by Gustav Albert Peter based on specimens collected in Tanzania

Résumé fourni par la source

Summary 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.
