Dendrobium carronii resembles Dendrobium canaliculatum but its flowers are quite distinct with purple-maroon petals that are narrower, a mentum that points backwards and often curves upwards towards the apex and a bright yellow lip with a low callus of three ridges, beaded and scarcely raised at the apex, on the oblong midlobe. Its inflorescence is characteristically produced at a right angle to the pseudobulb.
