Abstract
Pera manausensis Bigio & Secco, a new species of Euphorbiaceae endemic to Manaus, Amazonas, is described and illustrated. This species is closely related to P. decipiens Muell. Arg., P. bicolor (Klotzsch) Muell. Arg. and P. tomentosa (Benth.) Muell. Arg., but can be recognized by the following: leaf abaxial surface with entangled, lepidote-stellate trichomes; staminate flowers with calyx 3-lobed and pistillodium filiform; pistillate flowers with tomentose ovary, stigma 3-lobed, lobes bifid, and staminodia sepaloid, filiform. The affinities of the new taxon are discussed and a key to separate closely related species is presented.
