Corydalis densiflora C.Presl in Presl & Presl (1822: 10)

Type (lectotype, here designated):—SICILY. Scalamadaggio, June 1817, C. Presl s.n. ( PRC 454783!).

Note:— Corydalis densiflora was described from Sicily “in nemorosis Nebrodum” ( Presl 1822). We traced in PRC a specimen collected by Presl in 1817 at “Scalamadaggio”, a locality in Madonie mountains (“Nebrodi” in classical times). Thus, this specimen clearly conforms to the information provided by the protologue and is here selected as the lectotype. According to the study of type material, we can consider C. densiflora as endemic to Italy and Sicily ( Peruzzi et al. 2014, continuously updated at https://docs.google.com/spreadsheet/ccc?key=0AiJpWnsqul0MdG1hSk k1azBjN3BoLXB4VTAzc3l1Smc#gid=0). This taxon is recorded for central-southern Italy in Umbria, Lazio, doubtful in Abruzzo, Basilicata, Calabria and Sicilia ( Conti et al. 2005, Del Vico et al. 2014). During field investigations undertaken in 2013 we were able to confirm the presence of C. densiflora in Abruzzo and to identify as C. densiflora a population from Marche recently reported as C. solida ( Gubellini et al. 2014) . However, our observations on fresh material and the study of herbarium specimens in APP, BC, CAT, CLU, L, LD, MA, MPU, P, PAL and PRC evidenced a certain degree of morphological variability within C. densiflora , seemingly linked to geographical distribution. A biosystematic study is in progress to investigate this topic (Conti et al. 2014).
