The article discusses the findings of a study to describe the morphology of the new Famatinanthus genus of Asteraceae flowering plant found in the Andes of Argentina. It notes that the study was conducted through field observations and stereomicroscope examination of the herbarium specimens. Researchers have tentatively assigned Famatinanthus to the Onoserideae tribe due to its shrubby habit, solitary capitula, and bilabiate marginal corollas, and rounded style branches.

The article discusses a study which described new species of Capsicum (C.) from the Caatinga Biome, Brazil. It notes that the species are similar to C. parvifolium. It also mentions that Capsicum is a genus that can be recognized by the unlobed calyx bearing appendices or teeth. Particular focus is given to the lectotypification for C. parvifolium and the analysis of karyotype for the species.

The article presents information on a study which determined the identity of Witheringia (W. ) sellowiana, a narrow endemic species from São Paulo, Brazil. A review of the related literature on the studies of the family Solanaceae is offered. The typification of W. sellowiana and its transfer to Aureliana is described. Also listed are the distinctive taxonomical key to the species of Aureliana.

The article describes and illustrates three species of Capsicum from eastern coastal Brazil. Capsicum pereirae from Espirito Santo and Minas Gerais is related to C. flexuosum and C. schottiamon. Capsicum friburgense, endemic to a restricted area in Nova Friburgo is similar to species from Sao Paulo. A key to differentiate the wild Capsicum species from Brazil is provided.

Three new species of Deprea, found in Ecuador and Peru, are described and illustrated. Deprea pauciflora has close morphological affinities with D. sachapapa, from which it is readily distinguished by the hirsute leaves, heterodynamous stamens, and invaginatepyriform fruiting calyx always loosely enveloping the berry. Deprea pecaensis shows similarities to D. maculatifolia, D. dilloniana, and D. pumila, although it is characterized by a combination of 1-3 flowers per node, narrowly elliptic leaves without any white macules, corolla lobes-tube length ratio 1.5: 1.75, homodynamous stamens, non-mucronate anthers, exserted style, and membranous leaves. Lastly, D. zakii is similar to D. hawkesii and D. purpureocarpa, but it can be distinguished by a combination of a glabrous to glabrescent vegetative indumentum, a campanulate corolla with revolute lobes which are equal to or shorter than the corolla tube, short calyx lobes, and staminal filaments broadening gradually in width basipetally. Discussions on taxonomy, geographic distribution, and conservation status are provided, as well as an identification key to the 50 species of Deprea. [ABSTRACT FROM AUTHOR]
