Patima is characterized by its little-branched, generally woody habit; its paired leaves with interpetiolar, triangular, generally persistent stipules; axillary, few-flowered inflorescences; homostylous flowers with subglobose ovaries of 5-6 locules, and each locule with numerous ovules; truncate calyx limbs; salverform, yellow to pale green corollas with 5-7 valvate lobes; and baccate fruits. Patima was studied as a monotypic, poorly known genus of the Guianas by Delprete et al. (2005), who noted the presence of raphides in Patima; noted some previous taxonomic confusion around it and classified it in Hamelieae, where its valvate corolla aestivation is unique; and described its inflorescence position supranodal. Taylor & Lorence (2010) subsequently described a second species of Patima, and considered the corolla aestivation to be valvate-induplicate and the inflorescence position to be axillary.

Patima has been rather infrequently collected, at least until recently, and has been overlooked by several authors. Patima guianensis has also been misidentified as a species of Hoffmannia, which is indeed similar but differs in its imbricate corolla aestivation. Patima is also similar to Faramea maguirei, which is found in the same region but differs in its leaves with well developed submarginal veins, 4-merous flowers, and fruits with a single seed.
