Holotypes of three Turczaninow’s species names in Malvaceae s. str. rediscovered at the National Herbarium of Ukraine (KW), with nomenclatural comments

Turczaninow published in the mid-19^th century at least 58 binomials (species-rank names) in Malvaceae sensu stricto. In their nomenclatural overview of Turczaninow’s names in Malvaceae, Fryxell and Krapovickas (in 1990) reported several supposed holotypes of some names as “not located”. Here we report the re-discovery of three holotypes of species-rank names published by Turczaninow in Malvaceae, viz. Malva mathewsii (now considered a synonym of Fuertesimalva peruviana), M. scorpioides (now of Fuertesimalva chilensis), and Sphaeralcea galeottii (now Phymosia umbellata), discuss the current taxonomic status of these names, and provide several miscellaneous nomenclatural comments on some other names of taxa of that family. We confirm our earlier conclusion that holotypes (if applicable) of names published by Turczaninow in his Animadversiones… series are normally deposited in the Turczaninow Memorial Collection (KW-TURCZ, now at the National Herbarium of Ukraine, KW), if not indicated otherwise in the protologue. We also report an additional isoneotype of the name Sphaeroma floribunda (now Phymosia floribunda) discovered at KW and comment on some previous type designation in view of our newly discovered holotypes. Digital images of four type specimens are provided. Further digitization tasks at KW are emphasized, especially in view of the current wartime threats.
