Abstract
Preparation of the Flora of RIo Palenque has produced new insights into the status of some taxa which have been considered by the respective authorities as being of subspecific rank. We have taken the position that closely related plants which grow sympatrically, yet which do not hybridize naturally, should be treated as separated species, particularly when adequate morphological features for distinguishing them exist.
