Abstract When Werner Rauh described the new variety Deuterocohnia meziana var. carmineo-viridiflora, he did not carefully check data in his own field books and field diary which later resulted in inaccurate statements about the type locality and gathering date of the type. Beyond that he preserved material of the taxon as herbarium specimens both collected in the wild and obtained from plants cultivated in Heidelberg Botanical Garden. This caused some complexity in distinguishing type from non-type specimens in the herbarium of Heidelberg University (HEID) later. Within the scope of the Werner Rauh Heritage Project, we have gained deep insights into Rauh’s field notes and his method of working which has allowed us to identify vouchers of the specimen designated as Holotype in the protologue as well as the correct type locality and gathering date of the new variety.
