Biocultural heritage of the Caatinga: a systematic review of Myrtaceae and its multiple uses.

The Caatinga, an exclusively Brazilian biome, stands as a reservoir of remarkable biodiversity. Its significance transcends ecological dimensions, given the direct reliance of the local population on its resources for sustenance and healthcare. While Myrtaceae, a pivotal botanical family within the Brazilian flora, has been extensively explored for its medicinal and nutritional attributes, scant attention has been directed towards its contextual relevance within the Caatinga's local communities.

Are Mixtec Forgetting Their Plants? Intracultural Variation of Ethnobotanical Knowledge in Oaxaca, Mexico.

Erosion of ethnobotanical knowledge in indigenous communities has been reported increasingly in recent decades. This study quantitatively and qualitatively analyzed the variation of ethnobotanical knowledge in communities of the high Mixtec subregion. We interviewed 64 Mixtec about edible and medicinal plants.

Ethnomedicinal survey of a maroon community in Brazil's Atlantic tropical forest.

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 isolated maroon community of Afro-Brazilians in the Atlantic coastal rainforests of Bahia, Brazil, a global biodiversity hotspot. The studied community is exceptional in that the residents were defacto slaves until several years ago, with no access to western medicine.

Morphological analyses suggest a new taxonomic circumscription for Hymenaea courbaril L. (Leguminosae, Caesalpinioideae).

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.
