Coniolia bracteosn Huber, Bull. Soc. Bot. Gen. 11. 6: 191. 1914.

Aeisanthera bracteosa (Huber) Tloehne, Anex. Mem. Hutantin 1: ."4. 1922.

I have examined the following Mnseu Goeldi specimens, all collected by Ducke and determined by Huber: 8008 (holotype of C. bracteosa), from Alto Ariramba, 20/XII/1906; 10465, from Campos de Faro, 17/1/1910; 11636, from Campo grande, Parintins, 8/V/1911; and 12101, campinha de cabeceira de Lago Itapecuru, 30/VII/1912. These Brazilian collections agree perfectly with the Guianan material of A. tetraptera. The hypanthium and calyx are sparsely to moderately fine-setulose with gland-tipped hairs along the nerves, and not glabrous as described by Huber.
