35. Helminthotheca Zinn (ox-tongue)

About 5 species, Europe, Africa.

Traditionally, Helminthotheca has been treated as a specialized group within Picris by most authors (Barkley, 1986; Gleason and Cronquist, 1991), but Lack (1974) demonstrated that it is separable from that genus based primarily upon its unusual involucral bracts and beaked achenes, as well as some micromorphological traits. Preliminary molecular studies (Whitton et al., 1995) have placed Helminthotheca as the most primitive member of the Picris lineage, but taxon sampling has been far too incomplete for this conclusion to be well supported.
