Description:Distribution and Ecology - Distribution. Amazonian Brazil (Estado Amazonas and Territorio Acre), Colombia (Intendencia Meta), Peru (Dept. Loreto), and Ecuador (Prov. Santiago-Zamora).

Discussion:Amaioua hirsula P. & E. Nov. Gen. & Sp. 3: 25. pi. 230. 1845, type: without locality, Peru (probably Dept. Loreto), Poeppig 2823 (photo of type from Delessert herb., N Y ). The elongated hispid calyx-lobes of this species distinguish it from the other species of this genus. Duroia spraguei Wernli. ( K e w Bull. 1914: 66. 1914), described from Mocoa, Caqueta District, Colombia, collected by Sprague 369, apparently is conspecific with D. hirsuta. F r o m the description and photograph of the type, it seems to represent a pistillate plant of D. hirsuta. Although stated to differ from D. hirsuta in having solitary flowers, the solitary flower is characteristic of the pistillate plant of D. hirsuta, while the many flowered branching type is characteristic of the staminate plant. The densely long sericeous, very hispid ovary described for D. spraguei is likewise encountered in D. hirsuta, as are the subulate-setaceous sericeous-hispid calyx-lobes.
