scientific name

Alternanthera sessilis (L.)
status

 

Gomphrena polygonoides Linnaeus  , Species Plantarum 1: 225. 1753 View Cited Treatment .

"Habitat in America meridionali." RCN: 1682.

Basionym of: Illecebrum polygonoides (L.) L. (1762)  .

Type not designated.

Original material: [icon] in Hermann, Parad. Bat.: 17. 1698; [icon] in Sloane, Voy. Jamaica 1: 141, t. 86, f. 2. 1707.

Current name: Alternanthera sessilis (L.)  DC. ( Amaranthaceae  ).

Note: This name had frequently been rejected as a nomen dubium (e.g. by Pedersen in Darwiniana 17: 438. 1967 and Mears & Gillis in J. Arnold Arbor. 58: 62. 1977) before Mears (in Taxon 29: 91. 1980) attempted to dispose of the name by typifying it using material in Herb. Sloane 2: 106 ( BM-SL), which he stated would make it a synonym of Alternanthera sessilis (L.)  DC. However, his chosen type is not the material from which Sloane’s t. 86, f. 2 (which was cited by Linnaeus) was prepared, which is identifiable as A. paronychioides A. St.  -Hil. Although Mears’ intention was laudable, a neotype cannot be designated when original material exists (Art. 9.11). It appears that formal rejection of the name may be necessary.
