Methods A sample of Polish-language ethnobotanical literature 45 published sources from 1874-2005 and four collections of voucher specimens from 1894-1975 were analyzed. Errors were detected in the publications by comparing the data with existing knowledge on the distribution of plant names and species ranges. The voucher specimens were re-examined. A one-letter code was invented for quick identification of the credibility of data published in lists of species compiled from historical or ethnographic sources according to the source of identification voucher specimen Latin binominal botanical expert obvious widespread name folk name mode of use range physical description or photograph. To test the use of the code an up-to-date list of wild food plants used in Poland was made. Results A significant difference between the ratio of mistakes in the voucher specimen collections and the ratio of detectable mistakes in the studies without herbarium documentation was found. At least of taxa in the publications were identified erroneously mean rate was per publication and in half of these mistakes even the genus was not correct. As many as of voucher specimens on average per collection were originally erroneously identified but three quarters of the identification mistakes remained within-genus. The species of the genera Thymus Rumex and Rubus were most often confused within the genus. Not all of the invented credibility codes .
