Parietaria officinalis Linnaeus, Species Plantarum 2: 1052. 1753.

"Habitat in Europae temperatioris ruderatis." RCN: 7606.

Lectotype (Paclt in Phyton (Horn) 4: 48, f. 1 (left). 1952): Herb. Clifford: 469, Parietaria 1, sheet A (BM-000647535) .

Generitype of Parietaria Linnaeus (vide Green, Prop. Brit. Bot.: 193. 1929).

Current name: Parietaria officinalis L. ( Urticaceae).

Note: Townsend (in Watsonia 6: 365-370. 1968) rejected Paclt’s designation in favour of 1220.2 (LINN), arguing that Linnaeus did not have Clifford’s herbarium available to him when writing Species Plantarum and that the description was arguably based on the LINN sheet. However, the Clifford material is clearly original material for the name, despite the probable role of the LINN specimen; Paclt’s choice has priority and is accepted here with his use of “holotype” treated as a correctable error under Art. 9.8.
