Lactuca quercina Linnaeus , Species Plantarum 2: 795. 1753.

"Habitat in Insula Carolina Balthici." RCN: 5817.

Lectotype (van Raamsdonk in Wisskirchen in Feddes Repert. 108: 105. 1997): Herb. Linn. No. 950.1 ( LINN) .

Current name: Lactuca quercina L. ( Asteraceae ).

Note: Stearn (in Biol. J. Linn. Soc. 5: 11. 1973), in an account of Linnaeus’ Öland and Gotland journey of 1741, treated Lilla Karlsö, near Gotland, as the restricted type locality, and noted the existence of 950.1 (LINN). In his paper, he attributed restricted type localities irrespective of whether any material existed in LINN and, where specimens do exist, he does not refer to any of them as type specimens. The collection subsequently designated as the type shows no annotation associating it with Gotland.
