case_images: Amazon, because of the logistical challenges of conducting fieldwork in remote areas and under challenging conditions, including among communities less likely to speak Portuguese. Although the herbarium data are also few in areas with few literature reports, Fig. 1 shows that data from otherwise unstudied sites are incorporated by including herbarium specimens in any study.
case_images: Temporal patterns in the recording of medicinal data in herbaria. The graph shows the total number of herbarium specimens collected in each period and now deposited in the herbaria surveyed (line) and the proportion of those specimens with any associated information indicating whether or how the plant is used medicinal (bars).

case_images: Yet, we also show that later herbarium specimens in our study are more likely to include medicinal information (Fig. 2), suggesting a renaissance in Brazil in recording plant uses on herbarium labels.
