7b. Corylus cornuta subsp. californica View in CoL View at ENA (A.DC.) A.E.Murray

Kalmia View in CoL 12: 19 ( Murray 1982). – C. rostrata var. californica View in CoL A.DC., Prodromus Systematis Naturalis Regni Vegetabilis 16 (2): 133 ( Candolle 1864). – C. californica View in CoL (A.DC.) Rose, Garden & Forest 8: 263 ( Rose 1895). – C. cornuta var. californica View in CoL (A.DC.) Sharp, Relationships between the Floras of California and Southeastern United States: 58 ( Sharp & James 1951). – Type: USA, California, 1848, K.T. Hartweg 1960 (lecto-, designated here: G-DC! (G00478869); isolecto-: BR!, G00418163!, GH00033775!, K000859889!, K!). – Note: Corylus cornuta subsp. californica View in CoL is recognized in Flora of North America and World Checklist and Bibliography of Fagales ( Govaerts & Frodin 1998) View in CoL . The name C. californica View in CoL was published twice before Rose’s combination. Petzold & Kirchner (1864: 671) mention a plant in the park of Schloss Sanssouci Garden in Potsdam, Germany, but neither provide a description, nor explicitly recognize it as something different from C. avellana View in CoL , therefore their name is invalid. Koch (1873: 15) also mentions a C. californica View in CoL , but also mentions only its status as a cultivated plant without providing a description. Neither of the publications refers to Candolle, therefore, Rose’s combination is the first valid publication of this name.
