Both varieties of
X. paraensis in the Guianas, but particularly the type variety, are often confused with a common associate, X. savanensis. However, the former has smooth leaf and scape surfaces, broader dorsal areas, bearded staminodes and longer, narrower, conspicuously acuminate seeds, while X. savanensis in the same region has rugulose, papillose- scabrid scapes and foliage, has narrower dorsal areas, beardless, reduced staminodes, and shorter, plumper seeds with truncate and apiculate tip.
