Linaria tonzigii Lona [1949: 66 (–67, 65–72, figs. 1–4)]

Type (lectotype, designed here):— ITALY: Pizzo Arera, macereto vallone ovest, 2,300 m, July 1948. F. Lona s.n. (FI barcode FI002452!, image available at http://parlatore.msn.unifi.it/types).

Other original material:— ITALY: Mte Arera, dolomia, c. 2,200 m, 11 August 1911. [P. Chenevard s.n.] (G Herb. Chenevard barcode G00446127, digital image!).

Nomencaltural notes:— Lona (1949) described Linaria tonzigii providing a detailed description and reporting the following type locality: “In glareosis montis Arerae (dolomia) (Alpes Orobienses), 2000–2400.” Moreover, in the article he reported two pictures of dried specimens, one from his personal collection (with no label and collection information), the other one from the Herbarium Chenevard (G) with flowers in bud only, identified by Paul Chenevard (1839–1919) himself as Linaria thymifolia ( Vahl 1791: 67) DC. in Lamarck & Candolle (1805: 587). The latter specimen was subsequently considered a teratological form of Linaria alpina ( Linnaeus 1753: 615) Miller (1768 : Linaria No. 4) by Ernst Wilczek (1867–1948) (on the label it is written “galle de Mecinus sp. ”), that however Lona recognized as Linaria tonzigii . We traced this specimen in G and we confirm the Lona identification.

We are able to trace only one specimen, collected by Lona in Pizzo Arera prior to the publication of the name, deposited by the same author in FI (barcode FI002452) in 1950. This specimen completely agrees with the protologue (in this sheet, there are the same plants reproduced in the protologue) and can be considered as original material (Art. 9.4 of the ICN, Turland et al. 2018). The specimen FI barcode FI002452 is selected here as lectotype for the name L. tonzigii .

Distribution:— Linaria tonzigii is an Italian endemic exclusive of few localities of the Orobian Prealps (Lombardia) ( Orsenigo et al. 2016, Bartolucci et al. 2018).
