... The tribe Lavoisiereae (Melastomataceae) has been recognized as monophyletic based on morphological and molecular data (Fritsch et al. 2004;Versiane et al. 2021). Until recently, the tribe included the genera Chaetostoma DC., Lavoisiera DC., Microlicia D.Don, Rhynchanthera DC., Stenodon Naudin, Trembleya DC. (Fritsch et al. 2004), and Poteranthera Bong. ...
... (Rocha et al. 2016). However, the modern circumscription of Microlicia now encompasses Chaetostoma, Lavoisiera, Stenodon, and Trembleya (Versiane et al. 2021). Consequently, the tribe currently consists of only three genera. ...
... Microlicia presents pentamerous flowers, occasionally hexamerous to decamerous, a hypanthium with or without bristles, an isomorphic to dimorphic androecium, tetrasporangiate or polysporangiate anthers, a pedoconnective prolonged below the theca with a ventral appendage, a glabrous ovary apex, capsular fruit with basipetal or acropetal dehiscence, and a persistent or deciduous columella (Versiane et al. 2021). The genus comprises 286 species (Versiane et al. 2021), of which only eight occur outside the Brazilian borders (Romero et al. 2022). ...
Background and aims – The genus Microlicia consists of 286 taxa, 82 of which are found in Bahia, Brazil. This genus features pentamerous flowers, occasionally hexamerous to decamerous; a hypanthium with or without bristles, isomorphic to dimorphic androecium; tetrasporangiate or polysporangiate anthers; and pedoconnective prolonged below the theca with a ventral appendage. The ovary has a glabrous apex, and the fruit is capsular with either basipetal or acropetal dehiscence and a columella that can be persistent or deciduous. In this study, we describe three new species of Microlicia found in Bahia, Brazil, and provide a checklist of Microlicia species with yellow corollas.
Material and methods – The morphological descriptions are based on examinations of the Microlicia collections housed in six herbaria. Along with the descriptions, we provide comparisons with morphologically similar species, a distribution map, conservation status assessments, and illustrations.
Key results – We describe Microlicia aequalis, Microlicia eimeariana from Catolés, and Microlicia xanthopetala from Mucugê, Bahia, Brazil. We have preliminarily assigned these three species as Data Deficient (DD) according to IUCN Red List criteria.
... Microlicia D.Don is a diverse genus within Melastomataceae, primarily associated with cerrado and campo rupestre areas in the Neotropical region (Fritsch et al. 2004). Comprising approximately 300 species, most of them endemic to Brazil and a few species occurring in the Tepuis and Paramos of Bolivia, Colombia, Peru, Guyana, and Venezuela (Mendoza-Cifuentes et al. 2019, Pacifico et al. 2020, Versiane et al. 2020, 2021, Pacifico and Almeda 2022a. Microlicia currently encompasses taxa previously included in the genera Chaetostoma DC., Lavoisiera DC., Trembleya DC., and Stenodon Naudin (Versiane et al. 2021, Pacifico andAlmeda 2022a). ...
Microlicia ciliatobracteata sp. nov. is a newly described species from Guarani de Goiás municipality in the northeastern Goiás state, Brazil. This study provides a detailed description of M . ciliatobracteata , an illustration plate, an occurrence map, preliminary conservation status, and a comparison with morphologically related species: M. consimilis , M. denudata , M. piauiensis , and M. versianeae. Microlicia ciliatobracteata is readily distinguished from other Microlicia species primarily by its bracts and bracteoles with setose‐ciliate margins and flowers with subisomorphic stamens and polysporangiate anthers. We consider the new species ‘Data Deficient' (DD) since more knowledge on its distribution is necessary to provide an adequate conservation status.
... Minas Gerais is the most plant-diverse state in Brazil, housing 14,786 species of angiosperm (Flora & Funga do Brasil 2024) and is home to one-third of the Brazilian melastomes (Goldenberg et al. 2024). Among the neotropical melastomes, Microlicia D.Don is the second largest genus, with nearly 300 species (Versiane et al. 2021;Pacifico and Almeda 2022), mainly occurring in grasslands and campo rupestre areas of Minas Gerais (Pacifico et al. 2020). ...
One-third of Brazilian melastomes occur in Minas Gerais, the most floristically diverse state in the country. In this paper, we introduce Microlicia geraizeira, a new species of Melastomataceae exclusively collected in the Serra Nova e Talhado State Park, northern Minas Gerais. The new species has leaves, hypanthia, and sepals densely covered with spherical glands mixed with glandular trichomes, elliptic-lanceolate to oblong-lanceolate leaf blades, urceolate hypanthia, triangular to narrowly triangular sepals, pentamerous flowers, dimorphic and concolor androecium, tetrasporangiate anthers, and five locular ovaries. We compare M. geraizeira to M. gentianoides, M. indurata, M. macrantha, M. mellobarretoi, M. pilosa, and M. septentrionalis. Also, we provide an illustration plate, field images, an occurrence map, and an identification key for closely similar species.
... In Brazil, Melastomataceae stands out as the fifth largest angiosperm family (BFG 2022), comprising 59 genera and 1,483 species, out of which 10 genera are endemic to Brazil (Goldenberg et al. 2024;Michelangeli et al. 2019;Versiane et al. 2021; the number of genera according to Silva et al. 2023). The state of Minas Gerais ranks first in Melastomataceae richness, with 500 species distributed in the Cerrado and in the Atlantic Forest domains (Goldenberg et al. 2024). ...
The Serra do Rola-Moça State Park is located in the central southern portion of the Espinhaço Range, in a region known as the Iron Quadrangle in Minas Gerais, Brazil. Here, we provide a list of Melastomataceae species recorded in the main vegetation types found in the park, along with identification keys and illustrated plates portraying them. Currently, 60 species in eight genera have been catalogued for the park. Miconia is the richest genus in the area (24 spp.), followed by Microlicia (19 spp.), Pleroma (eight spp.), Cambessedesia (three spp.), Chaetogastra and Fritzschia (two species each), and Marcetia and Macairea with one species each.
...

... Most Microlicia species in Brazil are concentrated in the Espinhaço Range, with ten areas of endemism, including the Iron Quadrangle (Pacifico et al. 2020). Microlicia has merged with Chaetostoma De Candolle (1828: 112), Lavoisiera De Candolle (1828: 102), Stenodon Naudin (1844: 146), andTrembleya De Candolle (1828: 125), as most of the characters traditionally used to distinguish these genera are homoplastic (see Versiane et al. 2021). The genus is characterized by subshrubs to trees, sessile to petiolate leaves, secondary and tertiary nerves present or absent, flowers solitary or in inflorescences, 5-merous, rarely 9-10-merous, presence or absence of bristles at the hypanthium apex, ovary superior to inferior with basipetal or acropetal dehiscence, and columella caducous or persistent (Versiane et al. 2021). ...
Here, we describe Microlicia ferricola, a newly discovered species exclusive to the Iron Quadrangle, Minas Gerais state. Additionally, we provide an illustration plate, field images, occurrence map, and comparisons with its morphological relatives such as M. longicalycina, M. woodgyeriana, and M. trichocalycina. This new species is characterized by its green-reddish to reddish branches, leaves, hypanthia, and sepals covered with glandular trichomes, lanceolate to elliptic-lanceolate leaves, setose at the apices, campanulate-oblong hypanthia, long-triangular sepals, dimorphic and bicolorous androecium with tetrasporangiate anthers. Microlicia ferricola is found in the Serra do Rola-Moça State Park and is considered a Least Concern (LC) taxon since it is within a conservation unit, ensuring its preservation.
... The non-reproductive stage of the species did not allow material to be collected for deposit in a herbarium. The species identification was based on comparison with exsiccates deposited in herbaria in Brasília from materials collected by the authors themselves in previous years, as well as through exsiccates from materials published in the work of Costa ( (Versiane et al. 2021). However, the authors will use the epithets as published in <http://floradobrasil.jbrj.gov.br/>, ...
... Emergences are structures which are commonly found in some genera of Melastomataceae, such as Lavoisiera, Microlicia, and Rhynchanthera (Sousa 1997;Milanez & Machado 2011;Silva et al. 2018;Carmo et al. 2020), and Leandra and Tibouchina (Reis et al. 2005). Currently Lavoisiera is included in genus Microlicia (Versiane et al. 2021). According to Michelangeli et al. ...
Vereda (palm swamp) is a savanna vegetation type widespread in the Cerrado. This environment is characterized by high irradiance levels and waterlogged soils for part of the year, resulting in hypoxic conditions, organic matter accumulation, and nutrient limitation. Due to these characteristics, we expect leaf scleromorphism to be the predominant pattern in the community, thus ensuring the survival of Vereda plants in these harsh environments. We examined the leaves of 14 species in Vereda Grande in central Brazil to identify their anatomy. We also analyzed the light availability and edaphic aspects of the soils in which these plants grow. We found high irradiance and soils which were rich in organic matter but low in nutrients; these factors limit plant growth given the elevated aluminum values and low pH (mean of 3.6). Most species had thick leaves with a thick cuticle, a well-developed mesophyll, calcium crystals, phenolic compounds, and sclerenchyma. These results corroborate the expected pattern of scleromorphism predicted by the environmental conditions to which Vereda plants are subjected. Chelonathus alatus did not show a leaf scleromorphic pattern and avoided stress in the dry period by losing its shoots.
... It can be recognized by the opposite, exstipulate, acrodromous leaves and dichlamideous flowers with free petals, stamens usually twice as the petals, with poricidal or seldom rimose anthers (Judd et al. 2009). It is monophyletic (Maurin et al. 2021), but recent phylogenetic studies, based on molecular and morphological evidence, have proposed a new circumscriptions for the tribes (Penneys et al. 2010Michelangeli et al. 2011;Bacci et al. 2019;Bochorny et al. 2019) and genera, such as the polyphyletic Tibouchina, which was recently broken down into other genera (Michelangeli et al. 2013;Guimarães et al. 2019) and Miconia and Microlicia, with recent broader circumscriptions that include other former genera (Michelangeli et al. 2016Versiane et al. 2021). In these cases, Pleroma came to be treated as a genus, resulting in several nomenclatural changes (Guimarães et al. 2019), while Clidemia, Leandra, and Ossaea are now included in a broader Miconia (Michelangeli et al. 2016. ...
Melastomataceae is one of the richest families in Brazil, with 1,436 species, 158 occurring in the state of Paraná. Many of the species are pioneers and zoochoric, essential for regeneration and floristic composition of the Atlantic Forest, which is the phytogeographic domain covering the Iguaçu National Park (ParNa Iguaçu). We present the floristic inventory of Melastomataceae of ParNa Iguaçu. Three areas in the park were sampled from May 2019 to March 2020, where two are covered with Seasonal Semideciduous Forest (SSF), and the other in a transition between SSF and Mixed Ombrophilous Forest (MOF). Seventeen species of Melastomataceae in four genera were recorded: Miconia (14 spp.), Acisanthera, Chaetogastra, and Pleroma (with only one species each). Seven species occur in the two vegetation types in ParNa Iguaçu, while six occur only in MOF and four only in SSF. Of the 17 species, six are endemic to Brazil, four of which occur only in the south and southeast regions of the country. This study registers nine new records for the ParNa Iguaçu. Furthermore, the Miconia leaeichleri was collected for the first time in the western region of Paraná, which suggests the necessity for more collection efforts in the western region of the state.
... Microlicia D. Don (1823: 283, 301), one of three genera in the Neotropical tribe Lavoisiereae Candolle (1828: 100), has been recently recircumscribed, based on molecular data, to include Chaetostoma Candolle (1828: 112), Lavoisiera Candolle (1828: 102), Stenodon Naudin (1844: 146), and Trembleya Candolle (1828: 125), four traditionally recognized genera in the tribe (Versiane et al. 2021). With some 250+ species, Microlicia is now the second largest genus of Neotropical Melastomataceae and the fourth largest globally (Versiane et al. 2021;Pacifico & Almeda 2022a;Ulloa Ulloa et al. 2022). ...

Microlicia rosanae and M. septentrionalis are described as new species from campo rupestre in the Espinhaço Meridional and Septentrional of Minas Gerais, Brazil, respectively. Diagnostic illustrations, field photographs, a distribution map, recommended conservation assessments, and discussions of putative related species based on morphological similarities are provided. Microlicia rosanae, from Serra do Caraça, can be recognized by its sessile oblong to narrowly oblanceolate 1-nerved leaf blades that are revolute when dry, 5-6-merous solitary flowers, hypanthia that are copiously covered with a mixture of inconspicuous spreading short and longer (some gland-tipped) trichomes that are up to ca. 0.25 mm long, fruiting hypanthia that are conspicuously constricted into a short neck just below the torus, and 5-6-locular ovaries that are ca. ½ inferior. Microlicia septentrionalis, from Pico da Formosa in northern Minas Gerais, is readily recognized by its ovate-lanceolate leaves that are somewhat concave when fresh and have red callose-thickened margins, petals pink throughout with an asymmetrical red band on the abaxial surface, hypanthia (at anthesis) somewhat constricted distally above the ovary just below the torus into a neck 1-2.5 mm long, glabrous basally and distally with a sparse ring (sometimes interrupted) of gland-tipped trichomes mostly 0.5 mm long just below the constricted neck, and 5-locular ovaries that are 2/3 inferior and beset with glandular trichomes (up to 0.5 mm long) apically around the base of the style. Microlicia rosanae is compared to the superficially similar M. pilosa and M. septentrionalis is compared with M. mellobarretoi, M. gentianoides, and M. punctata. Both newly proposed species are known only from their respective type localities.
... Microlicia laniflora (D.Don) Baill. (Microlicieae, Melastomataceae) is a self-incompatible and endemic shrubby species restricted to the rocky outcrops of the campo rupestre of Minas Gerais State (Martins 1997;Soares and Morellato 2018;Versiane et al. 2021). Its showy white flowers of nocturnal anthesis are associated with a specialized buzz-pollination system mediated by large crepuscular bees (Soares and Morellato 2018), and its dry, capsular, and dehiscent fruits produce diminute self-dispersed seeds (Martins 1997;Soares and Morellato 2018). ...
... Microlicia laniflora is a woody, shrubby, and allogamous Melastomataceae species that is narrow endemic to rocky outcrops of the rupestrian grasslands at the southern portion of the Espinhaço mountain range (Martins 1997;Soares and Morellato 2018;Versiane et al. 2021; fig. 1A). ...
... With about 275-300 species, the near-endemic Brazilian tribe Lavoisiereae DC., which has long been known by the later tribal name Microlicieae Naudin, is one of the richest clades of Neotropical Melastomataceae (Fritsch et al. 2004;Versiane et al. 2021;Pacifico and Almeda 2022). Currently, three genera are accepted, i.e. ...

A systematic monograph of the Trembleya s.s. clade is presented, a Brazilian endemic lineage of Melas-tomataceae comprising 11 species and currently recognised as part of Microlicia s.l. (Melastomataceae). First, we investigate phylogenetic relationships within Lavoisiereae using two nuclear markers and two sampling datasets (102 and 134 terminals). Then, we provide a systematic revision and new circumscription of the Trembleya s.s. clade, including line drawings, photos of living specimens, leaves and floral parts, distribution maps, a key to the 11 accepted species, comments on morphology, reproductive biology, richness, endemism, biogeography and recommended conservation assessments. A nomenclatural update of all taxa previously treated in Trembleya is also provided, including the designation of 45 lectotypes and the proposal of 38 new synonyms.
