Typification of the names of three Sicilian endemic Orchidaceae published by Agostino Todaro

In the framework of the ongoing nomenclatural revision of the plant taxa described by Agostino Todaro, this paper is focused on three orchids described by him. The name Arachnites biancae (≡ Ophrys oxyrhynchos subsp. biancae) is here lectotypified with a specimen kept in PAL, while the names Arachnites fuciflora var. panormitana (≡ Ophrys exaltata subsp. panormitana) and Ophrys oxyrhynchos are neotypified using specimens preserved at P. Nomenclatural, taxonomic, ecological, and phytogeographical notes are provided for each taxon.
