Solanaceae Source

A global taxonomic resource for the nightshade family

Mar 19th, 2021 - Andrés Moreira Muñóz

Next SOL Seminar Online will be presented by Andres Moreira Muñoz on Advances in the knowledge of the Chilean Solanaceae and a taxonomic synopsis of the genus Schizanthus

Abstract. The family Solanaceae is the fourth most diverse in Chile, both in numbers of genera and species. The Chilean flora also shows outstanding levels of endemism in the regional context. Although there are no monographs for all genera to date, a synthesis of the state of knowledge about the diversity of the family in Chile is presented here, together with an analysis of the distribution of its most diverse genera (Solanum and Nolana), and their respective richness centers. Solanum has around 63 species in Chile (44 native and 19 endemic) distributed along the latitudinal gradient from the border with Peru at 17°35'S to the hyperhumid south around 50°S. Solanum species are also found in the Juan Fernández archipelago, Desventuradas Islands and Easter Island (Rapa Nui). The rediscovery of Solanum polyphyllum Phil. has recently been reported in the Atacama mountains. Finally, a taxonomic synopsis of the genus Schizanthus Ruiz & Pav is presented. We currently recognize 17 taxa (14 species plus 3 infraspecific taxa). This taxonomic treatment is based on the analysis of specimens from 30 herbaria. The genus has its main distribution in Central Chile; only two species surpass the Andes and are found in the Argentine provinces of Mendoza and Neuquén. Three new taxa have been described: Schizanthus porrigens subsp. borealis, Schizanthus carlomunozii and their variety dilutimaculatus, all of them from the coast of the Coquimbo region. Schizanthus litoralis var. humilis, is also a new combination. Morphological details and key characters, habitat, distribution information and presence in protected areas are shown for each taxon, together with a list of representative localities for the materials examined.
