Fossil berries reveal global radiation of the nightshade family by the early Cenozoic.

Fossil discoveries can transform our understanding of plant diversification over time and space. Recently described fossils in many plant families have pushed their known records farther back in time, pointing to alternative scenarios for their origin and spread. Here, we describe two new Eocene fossil berries of the nightshade family (Solanaceae) from the Esmeraldas Formation in Colombia and the Green River Formation in Colorado (USA).

Chromosome Evolution in the Family Solanaceae.

This review summarizes and discusses the knowledge of cytogenetics in Solanaceae, the tomato family, its current applications, and prospects for making progress in fundamental systematic botany and plant evolution. We compile information on basic chromosome features (number, size, morphology) and molecular cytogenetics (chromosome banding and rDNA patterns). These data were mapped onto the Solanaceae family tree to better visualize the changes in chromosome features and evaluate them in a phylogenetic context.

The Morelloid clade of L. (Solanaceae) in Argentina: nomenclatural changes, three new species and an updated key to all taxa.

Since the publication of the Solanaceae treatment in "Flora Argentina" in 2013 exploration in the country and resolution of outstanding nomenclatural and circumscription issues has resulted in a number of changes to the species of the Morelloid clade of L. (Solanaceae) for Argentina. Here we describe three new species: Chiarini & Cantero, , from wet high elevation areas in Argentina (Catamarca, Salta and Tucumán) and Bolivia (Chuquisaca and Tarija), Barboza & S.

A revision of the clade (Elaeagnifolium clade; subgenus Leptostemonum, Solanaceae).

The clade (Elaeagnifolium clade) contains five species of small, often rhizomatous, shrubs from deserts and dry forests in North and South America. Members of the clade were previously classified in sections , and , and were not thought to be closely related. The group is sister to the species-rich monophyletic Old World clade of spiny solanums.

A new species of Solanum sect. Acanthophora (Solanaceae) from Argentina and Brazil.

A new species of Solanum belonging to section Acanthophora (subgenus Leptostemonum) from Argentina and Brazil is described. Solanum neei Chiarini & L.A.
