“…Seithe (1962) classified Solanum using hair types and defined a group “chorus subgenerum Solanum ” as those species with simple or branched trichomes; within that taxon she followed Bitter (1917) in segregating subgenus Lyciosolanum from subgenus Solanum , and in maintaining all of Bitter’s sections. She placed these in a group of vining plants with sections Dulcamara (Dunal) Bitter (Dulcamaroid clade, Knapp 2013), Jasminosolanum Seithe (Dulcamaroid clade, Knapp 2013), Aculeigerum Seithe (Wendlandii+Allophyllum group, see Clark et al 2015) and Herpystichum Bitter (Potato clade, see Tepe and Bohs 2011). Danert (1970) also suggested a close relationship between sections Dulcamara , Jasminosolanum and Aculeigerum (equivalent in part to the Wendlandii/Allophyllum clade of Bohs 2005) and members of the ANS clade based on a shared vining habit.…”

“…The large size of Solanum and its poorly understood infrageneric structure has meant that Solanum taxonomy has proceeded in a piecemeal fashion until relatively recently and the genus has acquired a reputation of being intractable. A project funded by the United States National Science Foundation’s Planetary Biodiversity Inventory (PBI) program begun in 2004 has sought to accelerate species-level taxonomic work across the genus and has resulted in a series of monographic and phylogenetic treatments from both Old and New Worlds (e.g., Tepe and Bohs 2011; Stern et al 2013; Knapp 2013; Clark et al 2015; Wahlert et al 2015; Aubriot et al 2016; Vorontsova and Knapp 2016). An electronic monographic treatment of the entire genus is begin made available online in the web resource Solanaceae Source (http://www.solanaceaesource.org).…”

The (ANS)African Non-Spiny clade contains 14 species of mostly large canopy lianas or scandent shrubs confined to Madagascar (10) and continental Africa (4, with with one species reaching the southern Arabian peninsula). Members of the clade were previously classified in sections Afrosolanum Bitter, Benderianum Bitter, Lemurisolanum Bitter, Macronesiotes Bitter and Quadrangulare Bitter, and were throught to be related to a variety of New World groups. The group is an early-branching lineage of non-spiny solanums and characters shared with other vining New World solanums are homoplastic. The 14 species of the group occupy a wide range of habitats, from wet forests in western Africa to savanna and dry forests of southern Madagascar and dune habitats in South Africa. Many members of the group are highly variable morphologically, and habit can vary between shrub and canopy vine in a single locality. We here review the taxonomic history, morphology, potential relationships and ecology of these species; we provide keys for their identification, descriptions, full synonymy (including designations of lectotypes and neotypes) and nomenclatural notes. Illustrations, distribution maps and preliminary conservation assessments are provided for all species.

“…In that work, I repeated Michel Felix Dunal’s attribution of the type collection of Solanumtrifolium Dunal, a species endemic to the central Andes of Ecuador, to Ruiz and Pavón (Tepe and Bohs 2011). Ruiz and Pavón, however, never collected in Ecuador and, in fact, by the time that collection was made in August 1804, the pair had already been back in Spain for over six years (Figure 1).…”

In 1777, Spain sent The Royal Expedition to Peru and Chile, commonly referred to as the “Ruiz and Pavón Expedition”, to document the flora of this richly diverse part of its colonies. The Expedition was active in the New World for 38 years and was led by Hipólito Ruiz and José Pavón, who collected in Peru and Chile for the first 11 years before returning to Spain to work on publication of the Flora Peruviana, et Chilensis. Work on the ground for the reminder of the project in Peru and later Ecuador, was continued by Juan Tafalla and Juan Manzanilla. With few exceptions, all collections from the Expedition including types, have conventionally been attributed to Ruiz and Pavón despite the fact that Tafalla and Manzanilla were responsible for a large part of the collections. The purpose of this note is to bring to light the important but often overlooked figure of Juan Tafalla, to highlight his accomplishments as a collector and to increase precision in botanical nomenclature by giving him due credit by correctly attributing collections.

Solanum is one of the world's largest and economically most important plant genera, including 1245 currently accepted species and several major and minor crops (e.g., tomato, potato, brinjal eggplant, scarlet eggplant, Gboma eggplant, lulo, and pepino). Here we provide an overview of the evolution of 25 key morphological traits for the major and minor clades of this giant genus based on stochastic mapping using a well‐sampled recently published phylogeny of Solanum. The most evolutionarily labile traits (showing >100 transitions across the genus) relate to plant structure (growth form and sympodial unit structure), herbivore defence (glandular trichomes), pollination (corolla shape and colour), and dispersal (fruit colour). Ten further traits show evolutionary lability with 50–100 transitions across the genus (e.g., specialised underground organs, trichome structure, leaf type, inflorescence position and branching, stamen heteromorphism). Our results reveal a number of highly convergent traits in Solanum, including tubers, rhizomes, simple leaves, yellow corollas, heteromorphic anthers, dioecy, and dry fruits, and some unexpected pathways of trait evolution that could be explored in future studies. We show that informally named clades of Solanum can be morphologically defined by trait combinations providing a tool for identification and enabling predictive phylogenetic placement of unsampled species.
