ABSTRACT The ethnobotanical literature lacks joint analyses of the factors that may influence the differential use of medicinal plants. This study intends to fill that void by evaluating the local criteria for the differential use of medicinal plants in a rural community in Northeastern Brazil. We chose two health problems (influenza and constipation) characterized as diseases by local (emic) classification to address the following hypotheses: (1) the most important medicinal plants are easier to acquire; (2) the most important medicinal plants are perceived as being more efficient; and (3) the most important medicinal plants taste better (greater palatability). The plants mentioned in interviews were ranked according to the perception of their use...

Abstract The aim of this study was to characterize galls of three species of the Copaifera genus (C. sabulicola, C. luetzelburgii and C. depilis), which occur sympatrically in a Cerrado area from Bahia state. A total of 23 gall morphotypes were found, 9 morphotypes on C. sabulicola, 7 on C. luetzelburgii and 7 on C. depilis. Galls predominated on leaves and stems. The most abundant colours found among galls were brown and green. Regarding the period of the year, from 35,511 leaflets analysed, 16,322 were collected in the dry season and 19,189 in the rainy season. In the dry season, 1,635 leaflets having galls were observed, and the highest proportion was observed on C. luetzelburgii (16.31%). In relation to the rainy season, there is statistical difference...
