A new species of Pleroma, endemic to Southern Cadeia do Espinhaço in Minas Gerais, Brazil, is described. Pleroma piranii is morphologically similar to Pleroma velutinum but differs in having larger leaves 2.5 ̶ 7.1 × 1.4 ̶ 4.7 cm (vs. 2.4 ̶ 4.1 × 1.3 ̶ 2.1 cm in P. velutinum), that are densely sericeous on the adaxial surface (vs. moderately strigo...
This volume summarizes much of what is currently known about the systematics, phylogeny, classification, biogeography, and ecology of Melastomataceae, one of the ten largest families of flowering plants. The family is largely a tropical one that is mostly unknown to people who have spent their lives in temperate latitudes. A few northern-hemisphere...
The Neotropics harbor over a third of all known seed plant species, and their distribution is not homogenous. Understanding how this diversity arose and is maintained is a complex endeavor and likely dependent upon the area, vegetation type, or group of organisms studied. The Miconieae, with ca. 1900 species, are the largest tribe of the plant fami...
The classification history of the Melastomataceae is straightforward. It is summarized in two parts, the early history prior to the appearance of Triana’s system followed by a chronological history of the major systems of classification of the pre-molecular era through 1993. The early history begins with Jussieu who first recognized the Melastomata...
The tribe Merianieae is a strictly Neotropical group with ca. 300 species in eight genera: Adelobotrys, Axinaea, Centronia, Graffenrieda, Macrocentrum, Maguireanthus, Meriania, and Salpinga. The tribe is characterized by diplostemonous flowers, anthers with simple to complex dorsal connective appendages, lacking ventral appendages, short or absent...
The Melastomataceae, with some 5858 species, are among the 10 largest families of flowering plants. Melastomes are subcosmopolitan and mainly distributed in the tropics and subtropics, with a majority of the species in the Neotropics. The family consists of 173 genera, and, as currently understood, it is divided into 3 clades (subfamilies): the Kib...
The tribe Miconieae is a strictly New World group of ca. 1900 species of mostly shrubs and small trees, but also including herbs, epiphytes, and climbers. The taxonomic history of the group is very complex with anything from 28 to 17 genera recognized in the tribe. Generic delimitations have often relied on a few morphological characters that are p...
The Melastomataceae, with ca. 177 genera and 5858 species, are among the ten most species-rich families of angiosperms. Previous molecular phylogenetic analyses have recovered many infrafamilial clades that are incongruent with traditional classifications based on morphology. Here, we present the most taxonomically comprehensive phylogenetic analys...
This chapter summarizes the taxonomic history, phylogeny, and biogeographic relationships of the Lavoisiereae together with a descriptive characterization emphasizing morphological and anatomical adaptations to seasonally dry environments. We also provide an overview of reproductive biology, distribution and endemism, ecology and plant/animal assoc...
The Melastomataceae include some 5858 species predominantly distributed over tropical biomes across the planet. Despite consensus on some particular aspects in the history of the group (e.g., Gondwanan fragmentation does not explain disjunctions), other scenarios have not been fully evaluated (e.g., the role of land bridges), and the impact of mole...
Pyramieae contains 68 species belonging to three genera: Cambessedesia, Huberia, and Merianthera. We review the systematics and evolution of Pyramieae, including the history of tribal placement of the genera, phylogenetic relationships, taxonomy with emphasis on morphological characters that define the tribe and its genera, and general ecology and...
Seed morphology in the Melastomataceae has long been recognized as a variable trait with potential taxonomic, systematic, and evolutionary significance. However, seed diversity in the family has not been comprehensively studied and there is a lack of a consistent terminology to describe such variation. Therefore, the aim of this study was to provid...
Pyxidantheae (= Blakeeae) are a monophyletic tribe of Neotropical woody plants ranging from southern Mexico (Guerrero to Puebla and Veracruz southward) to the Amazon basin of Bolivia, Brazil, and French Guiana, and a few are found in the West Indies. Colombia, particularly the Pacific lowlands and slopes of the Cordillera Occidental, represents the...
The Astronieae, as traditionally circumscribed, comprise 136 woody species in four genera, Astrocalyx, Astronia, Astronidium, and Beccarianthus, and are endemic to the Malesian, Papuasian, and Pacific Island rainforests. Initial molecular phylogenetic analyses suggested the monophyly of some genera and the closer relationship between the Neotropica...
Here, we provide an assessment of the variation in both vegetative and reproductive characters within the Melastomataceae, including the subfamilies Olisbeoideae, Kibessioideae, and Melastomatoideae, and the many tribes recognized within the last few decades: an extremely large and diverse clade. These morphological and vegetative anatomical charac...
The number of species of Melastomataceae for which there is chromosome information has increased over 12-fold since 1975.

For decades, tropical ecologists distinguished primary (PH) and secondary hemiepiphytes (SH) as two structurally dependent life forms with an epiphytic phase at, respectively, the beginning or the end of their ontogeny. However, the use of these terms has been criticized repeatedly because the term “hemiepiphyte” suggests an unsubstantiated biologi...
Hemiepiphytic plants are defined by their ontogeny. They germinate on a host tree but later establish root contact with the soil. Most hemiepiphytes remain structurally dependent on their host for their entire life, but some, often referred to as stranglers, develop pseudotrunks that allow them to outlive their host. Unfortunately, the terminology...
The Cadeia do Espinhaço (also referred to as “Espinhaço Range”) is a mountain range that extends for more than 1,200 km from northern Bahia to southern Minas Gerais in eastern Brazil. Mountains in the Cadeia do Espinhaço usually have impoverished soils and complex micro-habitats, where outstanding levels of endemism are found. Pleistocene glaciatio...
The urge to organise the world around us is an essential part of human nature. Naming and categorising enable us to store and access information ef ciently. The need to name and categorise extends to the natural world and, in particular, to living organisms. The science underpinning this area of knowledge is called Taxonomy, and is as old as humani...
