"Habitat in America septentrionali." RCN: 3509. Lectotype (Croizat in Webbia 17: 191. 1962): Herb. Linn. No. 630.11 ( LINN ) . Current name: Euphorbia maculata L. ( Euphorbiaceae ). Note: Wheeler (in Contr. Gray Herb. 127: 75. 1939; Rhodora 43: 143, pl. 668B. 1941; Rhodora 62: 134-141. 1960) attempted to show that 630.4 (LINN) was the correct type. The papers which contributed to the extensive debate that followed are listed by Croizat (in Webbia 17: 187-188. 1962), and include Fosberg (in Rhodora 48: 197-200. 1946), who illustrated one of the LINN specimens and the cited Plukenet plate. However, 630.4 has been shown to be the type of E. hypericifolia L., and Croizat designated 630.11 (LINN) as the type of E. maculata . This choice has been accepted by authors such as Fosberg & Mazzeo (in Castanea 30: 199. 1965), Burch (in Rhodora 68: 156-160. 1966) and Benedi & Orell (in Collect. Bot. ( Barcelona ) 21: 31. 1992).
