Typifications and nomenclatural notes in Physalis (Solanaceae) from the United States

Physalis is an economically important and morphologically diverse genus of plants with solitary flowers and fruits that are enveloped by an inflated fruiting calyx. Although work to resolve phylogenetic relationships in this clade is ongoing, Physalis remains a taxonomically complex genus with multiple nomenclatural problems. Here, we review 28 species from the United States and their synonyms as well as clarification on the status of their types. We propose 53 typifications. We select a lectotype for 49 names and a neotype for three names (P. ixocarpa, P. linkiana, P. ramosissima). We additionally designate an epitype for P. longifolia.Fil: Pretz, Chelsea.
