Abstract

Dacryodes uruts-kunchae is described, illustrated, and contrasted with D. steyermarkii. It is from white-sand plateaus and slopes of the sub-Andean cordilleras east of the Eastern Cordillera of the Andes in Ecuador, and from eastern foothills of the Andes in Peru. The new species is unusual for a number of reasons: (1) relatively few Burseraceae are found in tropical pre-montane and montane habitats; (2) it is dominant where it occurs, a rare phenomenon for Neotropical Dacryodes; (3) its staminate flowers show three stages in the transition from disk+pistillode to “ovariodisk”; and (4) it has relatively small, densely glandular-punctate, sclerophyllous leaflets.
