Description:Distribution and Ecology - VENEZUELA. Apure: Reserva forestal San Camilo, alt 300 m, Steyermark et al. 101377 PERU. Loreto: Aguaytia, Schunke 1970/23; Huanuco: Tingo Maria, Zavortink 2282. BRAZIL. Territory Amapa: basin of Rio Jari, Nilo T. Silva 1282, 3038, 3125; Territory Rondonia: basin of Rio Madeira, Prance et al. 5367. This is the first record of this species from Territory Amapa, Brazil, from the State of Apure, Venezuela, and from Peru (Loreto and Huanuco).
Except for A. grisebachii, different in its smaller leaves, narrowly spiciform
staminate inflorescence, and small staminate perianth, A. splendida is the only abuta
in the Amazon Basin and adjoining floristically related regions in which the leaves
are at once pallid-tomentose beneath and quite smooth above, the reticulation
immersed in the epidermis. Its relationship to A. rufescens sens. str. is mentioned
under that heading. In the form of the staminate perianth and androecium it closely
resembles the allopatric, southeast Brazilian A. convexa, but is easily separated by the
smooth upper leaf-surface and dense often velvety tomentum of the lower. In the
type region and sporadically elsewhere the tomentose indument is permanently gray
or silvery in tint, but elsewhere may be yellowish (at least when dry) or even rufescent.
