Anthurium angustifolium Theófilo & Sakur., a new species of Anthurium (Araceae) sect. Urospadix subsect. Obscureviridia from Espírito Santo (Eastern Brazil) is described and illustrated. Anthurium angustifolium is closely related to A. viridispathum and A. gladiifolium. It differs from A. viridispathum by its deflexed leaves, purplish peduncle and spadix, and reddish berries, and from A. gladiifolium by its narrowly elliptic blades, with obscure secondary veins, and by a smaller number of flowers on the principal and alternate spirals. A key for Eastern Brazilian species of subsect. Obscureviridia is given and a comparison of the characters that separate A. angustifolium from related taxa is provided.

A preliminary taxonomic revision is presented of the Neotropical genus Heteropsis, widely known as the source of a regionally important non-timber forest product; a tough resistant root fiber used in craftware and furniture making. Eighteen species and one variety are recognized, including two new species, Heteropsis reticulata and Heteropsis vasquezii; Heteropsis melinonii is considered to be of doubtful status. Descriptions, illustrations, geographical distribution and taxonomic commentary for each species, and an identification key are provided. Lectotypes are designated for Heteropsis oblongifolia, Heteropsis rigidifolia and Heteropsis salicifolia. Short reviews are provided of taxonomic history, phylogeny, vegetative and reproductive morphology, growth cycle, uses, and conservation status.
