18. Chrysanthemum praealtum Vent., Descr. Pl. Nouv.: tab. 43. 1801.

Lectotypus (designated here): IRAN: Mt. Albourg, Bruguière & Olivier s.n. (G [G00341493]!; probable isolecto-: G [G00341494]!).

= Tanacetum parthenium (L.) Sch. Bip.

Notes. – Two gatherings have been located for this species: the specimen collected by Bruguière and Olivier in Iran in Ventenat’s herbarium and the cultivated specimen from Cels’s garden in G-DC [G00450767]. A second collection in Ventenat’s herbarium has no information on its origin. The Bruguière and Olivier collection is here designated as the lectotype. A second collection at G [G00341494] is considered as a probable isolectotype but could also represent a Cels’s garden collection and should then be considered as a duplicate of the material in G-DC.
