Original material for the endemic Iberian species Odontitella virgata, initially described as linifolia sensu Brot., non L., does not exist. A specimen from Valorado’s herbarium (LISU) is chosen here as neotype for the name of the species now placed in the monotypic genus Odontitella. The same specimen is selected as neotype for Euphrasia tenuifolia Pers., basionym of Odontites tenuifolia (Pers.) G. Don, the correct name for these in Odontites. In addition, a lectotype is selected for the synonym Odontites aragonensis Willk. Macrosyringion longiflorum, the type of the generic name Macrosyringion, is lectotypified here by a specimen deposited in the Lamarck collections in Paris (P-LA), since that French botanist was the author of the basionym Euphrasia longiflora and not Vahl, to whom authorship has hitherto been generally attributed.

Several names have been applied to Euphrasia linifo- type, whether under the separate genus Odontitella, or, lia sensu Brot., non L. Two of these names were published following some classical taxonomic treatments, e.g., in 1806: E. virgata by Link (1806: 138) in January (Stafleu Flora Europaea (Webb & Camarasa, 1972: 267), under & Cowan, 1985: 319) and E. tenuifolia by Persoon (1806: Odontites s.l., given that E. tenuifolia is the basionym of 150) in November (Stafleu & Cowan, 1983: 183). Odontites tenuifolius, the correct name for the species in Euphrasia virgata and hence Odontitella virgata Odontites. are undoubtedly based on the name misunderstood by Two illustrations are available from which to choose a Brotero.
