In Microlicieae taxonomical delimitation of Lavoisiera, Microlicia and Trembleya is problematic. This study aims to fill this gap by identifying leaf characters that are useful for taxonomy of these genera. Species of Rhynchanthera were also included in this study for comparison, since it is an early‐diverging genus of the tribe. Diagnostic characters of Lavoisiera include sessile leaves with spongy parenchyma composed of isodiametric cells, and acute margins with supporting tissue. Trembleya is distinguished by petiolate, microphyllous, and hypostomatic leaves. The presence of depressions on the leaf surface and a homogeneous mesophyll is observed only in species of Microlicia. The leaf characters observed in Rhynchanthera, together with the available phylogenetic studies, were important to indicate evolutionary tendencies in the leaf structure within Microlicieae. Thus, our results indicate a tendency for reduction in leaf size within the tribe, in relation to both the petiole and the lamina. This reduction, which is more pronounced in Microlicia, results in a greater anatomical heterogeneity, due to variations in the organization of both vascular and fundamental tissues.

“…The Chapada dos Veadeiros, located in the north-eastern part of the State of Goiás, is considered an important floristic component of the Cerrado biome with different phytophysiognomies at elevations that vary from 800 to 1650 metres ( Munhoz and Felfili 2006 ; Felfili et al 2007 ; Souza and Bove 2011 ; Romero et al 2017 ). The region stands out as one of the centres of diversity of Microlicieae , being related as a recent radiation area of the tribe, due to the high number of endemic rates and high endemicity scores ( Pacifico et al 2020b ).…”

“…The region stands out as one of the centres of diversity of Microlicieae , being related as a recent radiation area of the tribe, due to the high number of endemic rates and high endemicity scores ( Pacifico et al 2020b ). The region exhibits a significant number of endemic species of Chaetostoma ( Silva et al 2018 ), Trembleya ( Pacifico et al 2019 ) and Microlicia ( Pilger 1903 ; Wurdack 1959 ; Diniz-Neres and Silva 2017a , 2017b ; Romero et al 2017 ). Moreover, at least 20 species of Microlicia in the State of Goiás occur in the Chapada dos Veadeiros ( Naudin 1845 ; Cogniaux 1883 ; Pilger 1903 ; Smith 1955 ; Wurdack 1959 ; Almeda and Martins 2001 ; Romero et al 2017 ; Diniz and Silva 2019 ).…”

Microlicia gracilis and Microlicia xylopodifera, endemic to Chapada dos Veadeiros, Goiás State, Brazil, are described, illustrated and the conservation status is also provided. Both species resemble Microlicia ordinata and Microlicia ramosa that are also endemic to Goiás, by having sessile leaf with serrate and ciliate margin, pedicellate flower, triangular and short sepal and dimorphic stamens with bicolorous and polysporangiate anthers. However, M. gracilis differs by the long internode (2–4 mm long), concolorous, semi-amplexicaul and lanceolate leaf, and petal acuminate at the apex. Microlicia xylopodifera differs in having a robust xylopodium, horizontal or slightly ascending leaf and a dense crown of glandular trichomes at the apex of flower bud.
