“…In Peru alone 272 species of Solanum occur, of which 83 are currently listed as endemic (Knapp et al 2006; Särkinen et al, in review). Many new species continue to be described (e.g., Anderson et al 2006; Stern and Bohs 2010; Knapp 2010a,b; Farrugia and Bohs 2010; Tepe et al 2012; Särkinen et al 2013) from the Andean region, discovered both in the field and in the herbarium. Solanum comprises 13 major clades of which the spiny solanum clade corresponding to subgenus Leptostemonum is the largest (Särkinen et al 2013).…”

Four new species of “non-spiny” Solanum from South America are described. Solanum longifilamentum Särkinen & P.Gonzáles, sp. nov. (Morelloid clade) is widespread from Ecuador to Bolivia and is most similar to Solanum macrotonum Dunal from Central and northern South America. Solanum antisuyo Särkinen & S.Knapp, sp. nov. (Morelloid clade) is found on the eastern Andean slopes in Ecuador, Peru and Bolivia and is most similar to the widespread lower elevation species Solanum polytrichostylum Bitter. Solanum arenicola Särkinen & P.Gonzáles, sp. nov. (Morelloid clade) is found in low elevation habitats on the eastern Andean slopes and in Amazonia of Peru and Bolivia and is most similar to the higher elevation species Solanum aloysiifolium Dunal of Bolivia and Argentina. Solanum mariae Särkinen & S.Knapp, sp. nov. (Potato clade) is endemic to Cajamarca Department in Peru, and is most similar to the widespread Solanum caripense Dunal. Complete descriptions, distributions and preliminary conservation assessments of all new species are given.

“…Solanum is one of the most species-rich vascular plant genera in the tropical Andes (Jørgensen et al 2011), where many new species continue to be described (e.g., Anderson et al 2006; Stern and Bohs 2010; Knapp 2010a,b; Farrugia and Bohs 2010; Tepe et al 2012; Särkinen et al 2013a; Särkinen et al 2015). Here we describe two new Solanum species from Bolivia that belong to the Morelloid clade, one of major clades of non-spiny solanums (Weese and Bohs 2007; Särkinen et al 2013b).…”

Two new Bolivian species are described from the Morelloid clade of Solanum (section Solanum in the traditional sense). Solanum alliariifolium M.Nee & Särkinen, sp. nov. is found in montane forests between 1,900 and 3,200 m and is morphologically most similar to Solanum leptocaulon Van Heurck & Müll.Arg., also from montane forests in southern Peru and Bolivia. Solanum rhizomatum Särkinen & M.Nee, sp. nov. is found in seasonally dry forests and matorral vegetation in lower elevations between 1,300 and 2,900 m and is most similar to Solanum pygmaeum Cav., a species native to sub-tropical Argentina but introduced in subtropical and temperate areas worldwide.

“…Here we present a case study of MBS from Solanum , one of the most species rich vascular plant genera in the Andes. In Peru alone Solanum includes 299 species, of which 102 are endemic ( Knapp et al 2006 ; Jørgensen et al 2011 ), and many new species continue to be discovered (e.g., Stern and Bohs 2010 ; Knapp 2010a , b ; Farrugia and Bohs 2010 ). Currently we are in the process of revising the Morelloid clade, one of the largest groups of Solanum in the Andes lacking a taxonomic monograph.…”

A new species of Solanum sect. Solanum from Peru is described here. Solanum pseudoamericanum Särkinen, Gonzáles & S.Knapp sp. nov. is a member of the Morelloid clade of Solanum, and is characterized by the combination of mostly forked inflorescences, flowers with small stamens 2.5 mm long including the filament, and strongly exerted styles with capitate stigmas. The species was first thought to be restricted to the seasonally dry tropical forests of southern Peru along the dry valleys of Río Pampas and Río Apurímac. Results from species distribution modelling (SDM) analysis with climatic predictors identified further potential suitable habitat areas in northern and central Peru. These areas were visited during field work in 2013. A total of 17 new populations across the predicted distribution were discovered using the model-based sampling method, and five further collections were identified amongst herbarium loans. Although still endemic to Peru, Solanum pseudoamericanum is now known from across northern, central and southern Peru. Our study demonstrates the usefulness of SDM for predicting new occurrences of rare plants, especially in the Andes where collection densities are still low in many areas and where many new species remain to be discovered.
