Orient . Suppl.: 64. 1888 .  Isatis tinctoria subsp. athoa (Boiss.) Papan. in Strid, Mount. Fl. Greece 1: 238. 1986 . Type: “Hab. in monte Atho unde semina ex quibus hanc plantam colui retulit cl. Pichler”. Lectotypus (designated here): GREECE : “Mt Athos ”, cult. 1875, Pichler s.n. ( G-BOIS [ G00332612 fruiting plant]) . Syntypus : GREECE : “Mt Athos ”, cult. 1875, Pichler s.n. ( G-BOIS [ G00332612 flowering plant]) . Notes. – The plant was grown in Boissier’s private garden at Valeyres from fruit collected by Pichler in 1873, and the voucher was collected by Boissier in 1875. It is not known if Pichler made a voucher specimen of the fruits he sent to Boissier, but there is no such material in the Geneva herbaria. The lectotype is a collection folder of two sheets, the plants of each were collected by Boissier at different times of the year because each sheet has plants in early flower and others with mature fruit. However, no collection dates were given. The flowers in Isatis hardly have any taxonomic value, but the fruits are essential. Therefore, the fruiting material is designated as the lectotype and the flowering branches as a syntype .
