Hymenaea is a genus of the Resin-producing Clade of the tribe Detarieae (Leguminosae: Caesalpinioideae) with 14 species. Hymenaea courbaril is the most widespread species of the genus, ranging from southern Mexico to southeastern Brazil. As currently circumscribed, Hymenaea courbaril is a polytypic species with six varieties: var. altissima, var. courbaril,(More)
A transect was used to examine the environmental and biological descriptors of a compact vegetation mosaic in the Chapada Diamantina in northeastern Brazil, including the floristic composition, spectrum of plant life forms, rainfall, and soil properties that defined areas of cerrado (Brazilian savanna), caatinga (seasonally dry tropical forest thorny,(More)
ETHNOPHARMACOLOGICAL RELEVANCE Considerable medicinal plant research in Brazil has focused on indigenous and mixed-race (caboclo and caiçara) communities, but relatively few studies have examined the medicinal plants and associated healing traditions of the descendants of enslaved Africans. This study surveyed the medicinal plants employed by a relatively(More)
BACKGROUND AND AIMS The reproductive biology of Syngonanthus mucugensis and S. curralensis (Eriocaulaceae) was studied in areas of 'campo rupestre' vegetation in the Chapada Diamantina, north-eastern Brazil. These species are herbaceous and the individuals have a grouped distribution. Their leaves are united in a rosette, and their inflorescence is(More)
(Reproductive phenology of Melocactus (Cactaceae) species from Chapada Diamantina, Bahia, Brazil). This paper discusses the phenological strategies of Melocactus glaucescens Buining & Brederoo, M. paucispinus G. Heimen & R. Paul, M. ernestii Vaupel and M. ×albicephalus Buining & Brederoo, species from Chapada Diamantina, northeastern Brazil. Melocactus(More)
We examined the phenology of three species of Hymenaea L. through field observations in savanna, deciduous dry forest, and ombrophilous forest environments to assess the effects of different environmental conditions on the leafing and reproductive behaviors of the plant populations there. We also used herbarium data to examine flowering aggregation for the(More)
We investigated flowering phenology in a semiarid macroclimate along an environmental gradient encompassing neotropical savanna, transition, and seasonally dry tropical forest (SDTF) areas in the Chapada Diamantina Mountains, northeastern Brazil. We expected to find divergence in flowering patterns between the plant communities studied that would be(More)
Myrcia amazonica DC. occurs in gallery forest and “campo rupestre” vegetation in the Chapada Diamantina, Bahia State, Brazil—habitats with contrasting irradiance and humidity conditions. We evaluated variations in aspects of the cost–benefit relationships of leaf maintenance and photosynthetic activity (phenology, leaf age, gas exchange, and photosynthetic(More)
