Picris scaberrima Guss. in Tenore (1830: 113).

Type (lectotype, designated here):— ITALY. Calabria. In apricis prope Tarsia in Calabria, s.d., Gussone s.n. ( NAP!).

Tenore (1830) quoted a specimen collected in Spezzano Albanese by Thomas and another specimen collected by Gussone in Tarsia (“In Calabria legit primum cl. Thomas: Spezzano Albanese; nuperrime autem in iisdem locis Tarsiae cl. Gussonius invenit, et specimina mecum benevole communicavit”). We did not trace any specimen collected by Thomas, neither in the Herbarium Gussone nor in the Herbarium Tenore (both conserved in NAP). However, we found in the Herbarium Tenore (in NAP) a specimen collected by Gussone in Tarsia, which corresponds well to the protologue. The label of this specimen lacks collection date, but the analysis of the G. Gussone unpublished manuscripts allows to infer that this author visited Tarsia in 1827 ( A. Santangelo, pers. comm.). Hence, this sheet ( Fig. 2) can be considered as original material and is here selected as the lectotype. This typification fixes the application of P. scaberrima in line with its current usage (e.g. Sell 1976, Pignatti & Lack 1982). Herbarium material from BM, K and P was also checked, but no putative original material was found.
