A group of such critical plants. Several authors have reduced it to L. sapphirinia Hoffmgg. & Link, Fl. Port. I. 241, t. 42 (1809), but the more or less deeply bifid style of this latter and the shape of the seeds together with the more south- westerly distribution seem sufficient for valid specific distinction. Willkomm in Willk. et Lange, Suppl. 174 (1893) makes L. sapphirina itself a synonym of L. linogrisea Hoffmgg. et Link, while Nyman, Consp. Fl. Europ. 538 (1881), makes L. linogrisea a synonym of L. bipartita Willd. This diversity of opinion indicates the desirability of further field and cultural studies on this group. The place of valid publication of the name L. delphinioides is not quite certain. Gay first used the name, without description, in his account of Durieu's botanical journey in Asturias (Duriaei iter Asturicum Botanicum). The name was printed (as Linaria delphinoides Gay) on the labels of Durieu's 1835 collection, No. 258, but again without description. In the Kew Herbarium there is pinned on to.
