Discussion

Cordylanthus nevinii has relatively short inflorescence bracts, similar to those of C. rigidus subsp. brevibracteatus, which is sympatric. Cordylanthus nevinii can be distinguished by having only one fertile pollen sac per stamen and flowers much longer than the inflorescence bracts.

The corolla of Cordylanthus nevinii is very wide at the middle just proximal to the base of the adaxial lip. The flowers appear to have a pair of lateral pouches. This appearance is enhanced because the pouches are white, in contrast to the purple-veined adaxial lip.
