Boissier & Spruner described E. albidus   providing a detailed description, in Boissier (1846) and quoting the following type localities: “Hab. in Hymetto Atticae et prope Thebas Spruner (sub. Ech. ruthenico,)” We were able to trace two herbarium specimens housed in G-BOIS, which can be considered original material (Art. 9.4 of the ICN; Turland et al. 2018). These herbarium specimens are complete, well conserved and agree with the protologue and with the current application of the name. There are two sheets with identical labels: G00765089 and G00765089a. The specimen G00765089 is selected here as lectotype for E. albidus   .


Echinops albidus   was quoted for the Balkan Peninsula and for SE Italy according to Kožuharov (1976, as E. sphaerocephalus subsp. albidus   ). In Italy, it is indicated as doubtful for Abruzzo and Campania though still recorded in Basilicata ( Conti et al. 2018; Bartolucci et al. 2018). Thorough search did not reveal any records of the species from the reported localities in the Majella mountains ( Tammaro 1986). As these are the only findings published for Abruzzo, the species has been excluded from this region ( Conti et al. 2019). Similarly the occurrence in Basilicata and Campania is not supported by any specimens in FI, APP and in HLUC herbaria, thus, at the given point, it is to be excluded from Italy at all.

From the Ionian Islands, the species was first reported by Georgiou (1988, as E. sphaerocephalus subsp. albidus   ). Ac- cording to relevant literature ( Kožuharov 1976), it is said to differ from typical E. sphaerocephalus   by its smaller capitula (with involucres less than 18(-20) mm long) and accordingly smaller synflorescences, and by its glabrous involucral bracts. However, based on comparison with collections present in WU (from Greece, Albania, Bulgaria) this has to be corrected: with exception of young synflorescences, the material shows involucre lengths between (16-)18-22(-25) mm, and usually at least some of the (outer) phyllaries are furnished, so often sparse, with minute glandular papillae (of only c. 0.05- 0.1 mm) or subsessile glandular hairs at the tips (seen also in material from the type region). In the Ionian collections measurements of involucre length slightly exceed this with 19-25 (-27) mm and are more or less congruent with those of C European E. sphaerocephalus   . The latter differs from the Ionian (Corfu) plants by glandular hairs of the phyllaries up to 0.2 mm long, and present in abundance abaxially on the apical part of outer and middle phyllaries. In E. albidus   , leaves are more deeply divided and spines are longer than in typical E. sphaerocephalus   . We think that given the characteristic combination of features it is adequate to consider this taxon at the species level.
