Viola demetria Prolongo ex Boissier (1839: 73)

Synonyms:— Viola tricolor Linneus (1753: 935) var. demetria (Prolongo ex Boiss.) Nyman (1854 –55: 228) ≡ Viola arvensis Murray (1770: 73) subsp. demetria (Prolongo ex Boiss.) W. Becker (1904: 40 , 47)

Lectotype (first-step designated by Burdet et al. 1991):— Per totam Sierra de Yunquera , 20–25 Aprilis 1838, Prolongo [G, ex herbier Boissier (3 feuilles). “ Le lectotype est constitué par les spécimens montés sur la feuille n° 1; les autres sont des isolectotypes ”]; (second-step designated here):— SPAIN. Málaga : Per totam Sierra de Yunquera, 20–25 April 1838, Prolongo s.n. (G, ex Herbier Boissier, “Séries n’ayant par servi à la rédaction du Flora Orientalis ”, G00343993!; Fig. 1 )

Notes: —This name was previously typified by Burdet et al. (1991), providing the specification of the herbarium and the collection but not followed by any available number permanently and unambiguously identifying the lectotype (ICN, Recommendation 9C.1, Turland et al. 2018): “ G, ex herbier Boissier (3 feuilles). Obs. 1. Le lectotype est constitué par les spécimens montés sur la feuille n° 1; les autres sont des isolectotypes.”. Recently, the three not numbered sheets at G have been rearranged in two sheets and it cannot be ascertained which of them was selected as lectotype. Then, according to Art. 9.17 of ICN, the type citation of Burdet et al. (1991) must be accepted as the first-step lectotypification and it is narrowed to a single specimen, G00343993 ( Fig. 1 ), by a second-step lectotypification.

Viola demetria is a Spanish endemic with a distribution limited to the mountains of Andalucia.
