摘要：
Piptocarpha angustifolia (Vernonieae, Asteraceae), a new cite for the Argentinean flora. The genus Piptocarpha R. Br. contains 46 species widely distributed from southern Mexico to northeastern Argentina and southern Brasil. The species are scandent shrubs or rarely trees, with axilary inflorescences composed of globose clusters. For Argentina has been only reported to P. sellowii (Sch. Bip.) Baker as the single member of the genus. In the present paper is reported for the first time for Argentina to P. angustifolia Dusen ex Malme, which can be distinguished from the remaining species of Piptocarpha by the tree habit and the inflorescence clusters having a lesser number of heads, among other features.
