Lectotype : LECTOTYPE : G. Santi,Viaggio al Montamiata, tav. III (designated here by A. Chiarucci, G. Cristofolini and S. Crema).The original material by Santi, searched in several Italian herbaria (BOLO, FI, PI, RO, SI), could not be traced.The plant at the locus classicus
(see below) is no more extant. Fortunately, Santi’s diagnosis is accompanied by an excellent plate (Fig. 4) that we select as lectotype, in the absence of original exsiccata.
