“…The analyses of nrETS and nrITS resulted in incompletely resolved trees with several weakly-supported clades, making it impossible to evaluate the monophyly of most clades within Microlicia s.l. This was expected since these lineages have been recovered with very short branch lengths in family-level phylogenetic analyses, based on the multi-loci approach that used a larger sampling of Melastomataceae ( Penneys et al 2022 ). However, a clade that is diagnosable morphologically and is a good match to Trembleya s.s. of Pacifico et al (2019) was identified.…”

“…Seed micromorphological characters have been traditionally used in the tribal and generic classification of Melastomataceae ( Cogniaux 1883–1888 ; Baumgratz 1983 ; Fritsch et al 2004 ; Ocampo et al 2014 ; Goldenberg et al 2015 ; Penneys et al 2022 ). In fact, one of the synapomorphies attributed to the Lavoisiereae is the presence of ellipsoid to reniform seeds with a reticulate-foveolate testa ( Almeda and Martins 2001 ; Fritsch et al 2004 ; Rocha et al 2016 ; Martins and Almeda 2017 ; Pacifico and Almeda 2022 ).…”

Meanwhile, many new species are still being described from little-studied genera and/or resulting from fieldwork in areas that remain poorly known or underexplored botanically.…”

A systematic monograph of the Trembleya s.s. clade is presented, a Brazilian endemic lineage of Melastomataceae 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.

“…The resulting ML tree was rooted with Acanthella sprucei Benth. & Hook.f., as this species has been recovered as the first diverging lineage of Marcetieae in recent phylogenetic analyses (Reginato et al 2020(Reginato et al , 2022Penneys et al 2022). In this study, a node was considered to be moderately supported if it showed bootstrap support (BS) between 80-89%.…”

Abstract— Three new species of the Neotropical genus Marcetia are described and illustrated: Marcetia barbadensis, Marcetia minima, and Marcetia serratifolia. The three species are known from small isolated populations in mountains of the Chapada Diamantina, Bahia, Brazil. The recognition of Marcetia barbadensis and Marcetia serratifolia is confirmed with an updated molecular phylogeny of the tribe Marcetieae (based on ETS, ITS, accD-psaI, atpF-atpH, trnS-trnG, psbK-psbL, ndhF and rbcL), and by morphological and morphometric studies. In turn, the recognition of Marcetia minima, a new species known only from the type gathering collected about 30 yr ago, is based on analyses of leaf and anther connective shape, as well as linear measurements of vegetative and reproductive structures. Based on the new phylogenetic hypothesis for Marcetieae, we reconstructed the evolution of habit and petal color in the tribe, and showed that prostrate plants and white flowers evolved repeatedly from ancestors with an erect habit and pink to magenta petals. We also provide notes on the intergeneric relationships and phylogeny of Marcetia and evaluate the generic placement of the recently described Acisanthera saxatilis.

Systematics of the fleshy‐fruited Sonerileae (Melastomataceae)

With approximately 1080 species, Sonerileae is the second‐largest tribe in the Melastomataceae. Approximately 40% of the Sonerileae species belong to fleshy‐fruited genera (Catanthera, Heteroblemma, Kendrickia, Medinilla, Pachycentria, Plethiandra). Relatively few species, especially of the fleshy‐fruited taxa, have been sampled for phylogenetic study. Consequently, there is huge uncertainty resulting in many unanswered questions about their evolutionary history, including the monophyly of the largest genus, Medinilla. In this study, the phylogeny of the fleshy‐fruited Sonerileae was reconstructed using 385 nuclear and 81 plastid protein‐coding loci recovered from newly generated target capture and off‐target reads data, and previous studies. Our study revealed that the fleshy fruited Sonerileae belong to three lineages. Kendrickia is sister to an Afrotropical endemic clade. Heteroblemma and Catanthera belong to a second clade and are most closely related to some Phyllagathis and Driessenia species. Medinilla forms a third clade that also includes Pachycentria and Plethiandra. Within Medinilla, 15 clades are identified and characterized. To make Medinilla monophyletic, the genus is redefined to include Pachycentria and Plethiandra. Major lineages identified within Medinilla lay the groundwork for an infrageneric classification system. Areas of the phylogenetic tree with high conflict or weak sampling are identified to aid further studies in the tribe.
