Abstract

Two new species of Borreria are described: the first, Borreria johnwoodii from the Campo Cerrado area of the Noel Kempff Mercado National Park; the second, Borreria siberiana from the cloud forest of the Yungas, between 2600 and 3100 m above sea level. Declieuxia cordigera is recorded for the first time from Bolivia. Borreria nectarifera is shown to be synonymous with B. eryngioides var. affinis.
