Designated by: Carlón & al. (2012) [in press]. Domina & al. in Plant Biosystems 147(3) (2013) [N. B. The name was correctly lectotypified by Domina & al. in Plant Biosystems 147(3). 2013) because our lectotypification was not validly published].

Host: exclusively on Centaurea species, s.l. [e.g., Centaurea fragilis Durieu in Algeria], Compositae [Asteraceae] (Annotated Checklist of Host Plants of Orobanchaceae, accessed Apr 2010).


Taxonomic observations: Orobanche leptantha Pomel [O. curvata Pomel; O. icterica Pau], Orobanche loscosii L. Carlón & al. [O. ritro auct.], Orobanche kochii F.W. Schultz [O. ritro Gren.] and Orobanche elatior Sutton [O. stigmatodes Wimm.] are considered conspecific by many authors (e.g., Chater & Webb 1972: 292; Greuter & al. 1989: 260; Foley 2001: 71). But in our taxonomic treatment we have preferred to consider these taxa as different species, which have different morphological characters and, frequently, different host plants.

"Species imperfecte cognitae et dubiae" (Beck 1930: 301-302). We have recently recovered the name Orobanche leptantha Pomel as a priority name for Ibero-African plant Orobanche icterica Pau (Carlon & al. 2011: 97). Orobanche curvata Pomel, from our point of view, is only a yellow colour variant of Orobanche leptantha Pomel (Pomel 1874: 111, "Plante d'un jaune concolore pâle"). The yellow forms are relatively common in this species.

Morphological observations: "Etaines insérée près de la base du tube... pubescents, ciliés dans le bas ... Tige ... porvue de squammes allongées, nombreuses" (Pomel 1874: 111); "sépales simples subuninerviés ... corolle arquée ... lobes fortement denticulés. Plante concolore, d'un jaune pâle. Sur Centaurea fragilis. Oran" (Battandier 1890: 663). Obs. according to this author, Orobanche curvata Pomel should be included within Orobanche minor aggr.
