Ξ Zosima absinthifolia (Vent.) Link

Lectotypus (designated here): [TURKEY]: Hort. Cels, Ventenat s.n. (G [G00341310]!) (Fig. 5).

Notes. – When validating the name Heracleum absinthifolium, Ventenat referred to “Sphondylium orientale humulius, foliis absinthii”, a pre-linnean name coined by Joseph Pitton de Tournefort (1656-1708) in the herbaria of Vaillant and Jussieu. A specimen has been located in Herb. Vaillant and is here considered as original material [P00662760]. Further collections of Bruguière and Olivier from Turkey have been located in G-DC [G00477269]. The only collection f rom Cels’s garden in Ventenat’s herbarium is designated here as the lectotype. Recent revisions of the genus Zosima Hoffm. (Alava, 1987; Menemen & Jury, 2001) cited as type material a collection at G with the locality information taken from Ventenat; however no collection exists with this locality.
