Checklist and key of genera and species of the Lamiaceae of the Brazilian Amazon

A checklist and keys are provided for Lamiaceae native to Brazilian Amazonia (eight genera and 42 species), excluding the genera Vitex, Volkameria, Aegiphila and Amasonia, which have recently been transferred from the Verbenaceae, and for which the author did not have data. An herbarium voucher is listed for each state in which the species has been found. Notes on many cultivated taxa are included, and also a key to all species of Ocimum known from Brazil

Hyptidendron albidum (Lamiaceae, Hyptidinae), a remarkable new species from northern Minas Gerais state, Brazil.

Hyptidendron albidum a new and endemic species from Northern Minas Gerais state, Brazil, is here described. This new species is unique due to the morphological combination of its dense indumentum of white dendroid trichomes, covering much of the plant and the inflorescence composed of a unilateral cymose structure. The new species is morphologically similar to H. unilaterale which displays a similar unilateral cymose structure but differs in its indumentum, inflorescence length and leaf morphology. We provide a description, an illustration, a conservation status assessment, a distribution map, and comments on the recognition of this new species

Updating the checklist of subtribe Hyptidinae (Lamiaceae) from Brazilian Amazonia, with three new taxa and notes on Hyptis sect. Eriosphaeria.

Abstract Three new taxa of subtribe Hyptidinae (Lamiaceae) from Amazonian Brazil are here described: two from Pará state Eriope macrostachya var. amazonica, and Hyptis cachimboensis, and Hyptis spathulata from Rondônia state. The diagnostic characters, which distinguish them from their closest relatives are described and discussed, their conservation status is given and a plate is provided for each of the new taxa. The Hyptidinae conspectus an earlier checklist of Lamiaceae from Amazonian Brazil is updated with various name changes since its publication, and with the addition of another two species of Hyptis not previously included. Also included, is a note on Hyptis sect. Eriosphaeria, to which the two new species described here, belong. Resumo Três novos táxons da subtribe Hyptidinae (Lamiaceae) da Amazônia Brasileira são aqui descritos: dois do estado do Pará, Eriope macrostachya var. amazonica e Hyptis cachimboensis, e Hyptis spathulata de Rondônia. Os caracteres diagnósticos destes novos táxons são descritos e discutidos, incluindo o status de conservação, além de pranchas para todas as novas taxons. A parte do checklist da subtribo Hyptidinae da Amazônia do Brasil é aqui atualizado com algumas mudanças de nomes desde sua publicação, e com a adição de duas espécies não previamente incluídas. Também, foram incluídos comentários sobre Hyptis sect. Eriosphaeria, a qual as duas novas espécies aqui descritas pertencem
