Kopsiopsis

Kopsiopsis (Beck) Beck in Engler (1930: 304) Ξ Orobanche sect. Kopsiopsis Beck (1890: 74 , 85)— Type: Kopsiopsis hookeri (Walp.) Govaerts (Ξ Boschniakia hookeri Walp. ).

Kopsiopsis hookeri (Walp.) Govaerts (1996: 14) ≡ Boschniakia hookeri Walpers (1844: 479) ≡ Orobanche hookeri (Walp.) Beck (1890: 85) ≡ Orobanche tuberosa Hooker (1834: 92) , nom. illeg., non Vellozo (1829: 257) ≡ Boschniakia tuberosa Jepson (1925: 954) , nom. illeg. ≡ Kopsiopsis tuberosa Beck in Engler (1930: 304), nom. illeg.— Type: N.W. Coast of America, A. Menzies s.n. (K).

Kopsiopsis strobilacea (A.Gray) Beck in Engler (1930: 306) ≡ Boschniakia strobilacea A. Gray (1856: 118) — Type : United States of America. California: Yuba County, 23 May , 1854, J. M . Bigelow s.n. (holotype, GH, barcode 00071672!; isotype, NY) .

When establishing Orobanche sect. Kopsiopsis, Beck von Mannagetta (1890) had recognized that Orobanche tuberosa Hooker (1834: 92) is a later homonym of O. tuberosa Vellozo (1829: 257) . Therefore, on the basis of B. hookeri, Walpers (1844: 479) proposed a combination O. hookeri , which is a replacement name for O. tuberosa Hook. Later, Beck von Mannagetta (1930: 304) adopted the illegitimate combination “ K. tuberosa (Hook.) Beck ” in his separated genus Kopsiopsis . Under this situation, “ K. tuberosa Beck ” cannot be adopted as a new name based on the same type (Article 58.1), because it was a superfluous name by citing B. hookeri and O. hookeri in the synonymy. Moreover, the replacement name “ B. tuberosa Jeps. ” (1925: 954) also must be rejected as a new name, because B. strobilacea was listed in the synonymy.
