"Habitat in Austria." RCN: 1127. Type not designated. Original material: Herb. Linn. No. 191.20 ( LINN ) ; [icon] in Clusius, Rar. Pl. Hist. 2: 164. 1601. Current name: Echium sp. ( Boraginaceae ). Note: Lacaita (in J. Linn. Soc., Bot. 44: 423. 1919) discussed this name in some detail, and Piggin (in Muelleria 3: 277. 1977) notes that it has been discarded as ambiguous because it is a mixture of E. rubrum Jacq. and E. rosulatum Lange. It appears to be a candidate for rejection.
