Schizanthus: the backstage of a synopsis and future perspectives
Schizanthus Ruiz & Pav. is a small genus (ca. 16 sp.) within Solanaceae, comprising annual and perennial herbs which are endemic to the South cone (Chile and Argentina). According to the phylogenetic analysis, Schizanthus forms a clade at the base of the family, being the sister group of all other Solanaceae. While working on the synopsis of the genus (Morales-Fierro et al., 2020), we faced several challenges to clarify some of the taxonomic problems of the group. One of the main ones was the lack of nomenclatural types since some species were described from cultivated specimens that were not conserved at herbaria. On the other hand, species identification from herbarium specimens is difficult, as most of them lose color and hide morphological characters which are essential for identification. Finally, the COVID lockdown prevented us from doing fieldwork or even reviewing some collections. However, it was a good opportunity to test how far we can go with online sources. That is why this talk rescues the taxonomic work that we can carry out through new sources of information (e.g. illustrations, databases, digital herbarium specimens, etc.) and the process that we follow to obtain our results. Additionally, we will mention some of the problems or questions that remained unresolved due to the limitations mentioned above.
