Clifford: 229,  Ranunculus8 (BM-000628885).   Note: Ranunculus auricomuswas treated as the generitypeby Britton & Brown ( Ill. Fl. N. U. S., ed. 2, 2: 104. 191); see McNeill & al. (in Taxon36: 381. 1987). However, under Art. 10.5, Ex. 7 (a voted example) of the Vienna Code, this is a type choice made under the American Code and is to be replaced under Art. 10.5b by Green'schoice ( Prop. Brit. Bot.: 163. 1929) of  R. acrisL.  Jasiewicz (in Fragm. Fl. Geobot.2: 70. 1956), aware that 715.21 and 715.22 (LINN) represented more than one taxon (illustrated as t. 4, f. 1,2), rejected the name as a nomen ambiguum.Kvist (in Ann. Bot. Fenn.24: 73-77. 1987) also discussed and illustrated (as f. 2 and 4) these specimens and concluded that 715.22 (LINN) should be the lectotype. These authors were apparently unaware of Benson'searlier choice, as noted by Ericsson (in Ann. Bot. Fenn.29: 134. 1992), who also discusses the possible identity of the type. 2611571438 BM BM-000628885 lectotype
