Deprea micrantha (Solanaceae), a new species from Ecuador, is described and illustrated in detail. Deprea micrantha Barboza & S. Leiva is found in San Francisco Biological Reserve, km 274½ between El Tambo and Sabanilla (Zamora-Loja route), province of Zamora Chinchipe, Ecuador, between 1874-1922 m of elevation. We include data concerning its relation with other similar species, geographic distribution, ecology, phenology, current status, common name and uses of the species. [ABSTRACT FROM AUTHOR]

Deprea auccana S. Leiva, Barboza & Deanna and D. physalidicalyx Leiva, Barboza & Deanna (Solanaceae) are described and illustrated. Deprea auccana inhabits Abra Patricia Private Reserve (ECOAN, Pomacochas-Nueva Cajamarca road, District Yambrasbamba, Prov. Bongará, Dept. Amazonas, Peru). This species is distinguished by the shape and size of its leaves, number of flowers per node, length of calyx lobes, homodynamous stamens, and its erect fruits with a fruiting accrescent calyx bipartite when mature. Deprea physalidicalyx S. Leiva, Barboza & Deanna inhabits in the Aguashiyacu waterfall (Tarapoto-Juanjuí road, Prov. Tarapoto, Dept. San Martín, Peru) and it is characterized by the corolla lobes deep purple on the middle and cream on the margins internally, homodynamous stamens, and the creamy berry when mature loosely enveloped by a fruiting calyx very accrescent and inflated, 3.5-4 cm long, 2.3-2.7 cm diameter. Data about geographic distribution, ecology, phenology, conservation assessment and differences with related species are included. [ABSTRACT FROM AUTHOR]

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 Solanum L. (Solanaceae) for Argentina. Here we describe three new species: Solanum hunzikeri Chiarini & Cantero, sp. nov., from wet high elevation areas in Argentina (Catamarca, Salta and Tucumán) and Bolivia (Chuquisaca and Tarija), S. marmoratum Barboza & S.Knapp, sp. nov., from central Argentina in Catamarca, La Pampa, La Rioja, San Juan and San Luis, and S. tiinae Barboza & S.Knapp, sp. nov., from the mountains of Jujuy, La Rioja, Salta and Tucumán. We provide descriptions, illustrations and distribution maps for all new taxa. A table of nomenclatural changes and additional taxa now known to occur in Argentina summarizes additions and changes since the "Flora Argentina". We also provide an updated key, including all new taxa for the country, to facilitate identification and further exploration. [ABSTRACT FROM AUTHOR]
