Eriope barrinhae (Lamiaceae, Hyptidinae), a new montane species from northern Minas Gerais, Brazil

Nordic Journal of Botany, Volume 2026, Issue 8, August 2026.
In northern Minas Gerais, in the Monte Azul region, the Pico da Formosa mountain remains poorly explored botanically despite recent discoveries of new taxa. During fieldwork at the summit of this mountain, we discovered a distinctive population of Eriope that differs from all known species by a unique combination of morphological characters.

Functional decay in tree community within tropical fragmented landscapes: Effects of landscape-scale forest cover.

PLoS ONE, 2017
As tropical rainforests are cleared, forest remnants are increasingly isolated within agricultural landscapes. Understanding how forest loss impacts on species diversity can, therefore, contribute to identifying the minimum amount of habitat required for

New canopy legume species highlight liana gap sampling across Amazonian and Atlantic rain forests

TAXON, Volume 75, Issue 4, August 2026.
Abstract Lianas are a key component of the Neotropical flora, accounting for 10% of angiosperm richness and playing important ecological roles. However, the canopy preference of some species often leads to their underrepresentation in herbarium collections, thereby exacerbating Linnaean, Darwinian, and Wallacean shortfalls. The papilionoid legume genus
