Abstract

Borreria santacruciana and  Mitracarpus bicrucis from Bolivia are described and illustrated. B. santacruciana is close to  B. wunschmannii, but differs for having inconspicuous pubescence of apressed hairs, leaves 7-17 mm long, glomerules with an involucre of 2-4 bracts of 7-13 mm long. Mitracarpus bicrucis is enterely glabrous, notable for its stipular sheath with only one lacina and seeds with a cross-shaped furrow on  both surfaces.
