Equisetum arvense Linnaeus, Species Plantarum 2: 1061. 1753.

"Habitat in Europae agris, pratis." RCN: 7730.

Lectotype (Jonsell & Jarvis in Nordic J. Bot. 14: 148. 1994): Clayton 341 (BM-000062951).

Current name: Equisetum arvense L. ( Equisetaceae).

Note: Hauke (in Nova Hedwigia 13: 106. 1966) indicated Löfling 713 (1241.4 LINN) as "a type for the name", but he believed that it was a post-1753 addition to the herbarium, and evidently treated it as a neotype. As original material is in existence, designation of a neotype is contrary to Art. 9.11, and Jonsell & Jarvis therefore rejected Hauke’s choice in favour of a Clayton collection.
