"Stelis dies-natalis is recognised by the relatively large plants with short, successive inflorescences, born from a small bract, the apiculate petals, the short, thick, conspicuously apiculate lip that is yellow with dark purple warts. It is somewhat similar to Stelis hydra but can be distinguished especially by the short inflorescence bearing dark purple flowers, with a yellow lip covered by dark purple warts, the apex of the petals apiculate and the lip with a shortly acuminate apicule."
