Visual stimuli are being used more and more in ethnobotanical research to elicit information about the use of
plants. However, the effectiveness and reliability of the information obtained through these methods are very rarely
discussed in the literature. In this work, the combined use of exsiccates and photographs to collect information about the
uses and vernacular names of plants from anthropogenic areas in a semi-arid area in the Northeast of Brazil was analyzed.
In general, this study verified that 91% of the plants were recognized by at least one of the interviewees. However, the
majority of those interviewed recognized only a small group of plants. Moreover, the recognition of a plant was not
related to its local abundance.
