Two new genera and a new species of Anacardiaceae from northern South America

Resumo

Cyrtocarpa is a generic name that has been applied to members of a complex of dry-habitat Neotropical taxa, but recent investigations have revealed that in fact this group represents three distinct genera. Tumultivenia and Uniostium, two new genera of Anacardiaceae-Spondioideae.are described and illustrated, as is one new species, Cyrtocarpa caribaea Both new genera are strongly supported as distinct in a published phylogeny. Uniostium velutinifolium was originally published in Bursera and subsequently combined in both Tapirira and Cyrtocarpa, while Tumultivenia caatingae was originally published in Cyrtocarpa. The number of locules and number and position of opercula in the pyrene provide the salient characters distinguishing these genera. The new species is a distinctive member of Cyrtocarpa sensu stricto but requires more collections (including fowering material) as well as material for molecular studies.
