A new rheophytic species of Euceraea (Flacourtiaceae) from Sierra de la Neblina, Venezuela

Abstract

Euceraea rheophytica is newly described and illustrated. It differs from the two other species in the genus, E. nitida and E. sleumeriana, in its much smaller and narrower leaves and in its smaller, spicate (vs. branched) inflorescences. It is known only from frequently flash-flooded riverbanks in the large, central canyon of the Sierra de la Neblina massif in southernmost Venezuela.
