Abstract:

The Leptostemonum Clade, or the ‘spiny solanums’, represents half of the species diversity of the large cosmopolitan genus Solanum (Solanaceae). Brazil is a centre of both species and lineage diversity in ‘spiny solanums’ with a number of lineages occurring mostly only there. Here, we treat the Solanum hexandrum group, a monophyletic species group that is part of the larger and unresolved Erythrotrichum clade sensu lato. The six species treated here are all robust very prickly shrubs with amongst the largest and showiest flowers in Solanum and accrescent calyces in fruit that often completely

Abstract:

The Leptostemonum Clade, or the “spiny solanums”, is the most species-rich monophyletic clade of the large cosmopolitan genus Solanum (Solanaceae) and represents almost half the species diversity of the genus. Species diversity in the clade is highest in the Americas, but significant clusters of endemic taxa occur in the Eastern Hemisphere. We present here a taxonomic revision of the 51 species of spiny solanums occurring in tropical Asia (excluding the island of New Guinea, and the lowlands of Nepal and Bhutan). Three species are described as new: Solanum kachinense X.Aubriot & S.Knapp, s

Abstract:

A new species of <i>Solanum</i> is described from Peru.<i> Solanum junctum</i><b> </b>S. Stern & M. Nee, <b>sp nov. </b>is a member of the Torva clade of the spiny solanums (Leptostemonum clade). The narrow corolla lobes and recurved prickles of <i>S. junctum</i> are similar to species in the Micracantha clade, but <i>S. junctum </i>differs in its branched inflorescences and upright green fruits. These characteristics are shared with other members the Torva clade; within this section <i>S. junctum </i>is morphologically most similar to <i>S. subinerme</i> and <i>S. poinsettiifolium</i>. <i

Abstract:

Solanum mellobarretoi, a new species of Solanum subg. Leptostemonum (Solanaceae), is described and illustrated. It is endemic to Brazil and restricted to the southern Espinhaço Range in the State of Minas Gerais, southeastern Brazil. Solanum mellobarretoi is morphologically related to S. leptostachys Dunal, from which it differs by its irregularly lobed lanceolate to ovate-lanceolate leaves, irregularly lobed, ovate to lanceolate calyx lobes, larger flowers, and pentagonal rotate corolla with cuspidate lobes. Although known in other groups of Solanum, the explosive seed dispersal mechanism fou

Abstract:

A <i>Solanum</i> species long considered an American introduction to the Cape Verde Islands off the west coast of Africa is identified as <i>Solanum rigidum</i>, a member of the Eggplant clade of Old World spiny solanums (<i>Solanum</i> subgenus <i>Leptostemonum</i>) and is probably endemic to the Cape Verde Islands. Collections of this species from the Caribbean are likely to have been introduced from the Cape Verde Islands on slave ships. We discuss the complex nomenclatural history of this plant and provide a detailed description, illustration and distribution map. The preliminary conservat

It is known from only three localities in Espírito Santo and Minas Gerais states, where granitic/gneissic outcrops (inselbergs or sugar loaves) are ubiquitous.
