REVISION OF NEOTROPICAL CALYCOBOLUS AND PORANA (CONVOLVULACEAE)

Abstract

The neotropical species of Calycobolus (Convolvulaceae) are revised. Three species are recognised. A fourth species is here recognised as belonging to the genus Porana. All four species are described, keys for identification are provided, selected characters are illustrated, distributions are mapped, and an index to numbered herbarium specimens examined is included to aid herbarium curation.
