Cogniaux compared this species to Veyretia sagittata but it has much shorter sepals and the lateral lobes of the lip are rounded versus unguiculate in V hassleri but a better comparison is with Veyretia neuroptera but V hassleri has lateral lobes on the basal portion of the lip versus none to slight and the midlip has a cushion towards the base and the apex of the lip is ovate and entire versus no cushion and the apex is spathulate with an apcial isthmus carrying a triangular extension.
