"Related to Brachionidium juliani but differs in the much larger habit and flowers. the lip is twice braoder with a minutely denticulate margin, the lip of B julianii has a double, denticulate margin and is much narrower. In habit B renzii resembles Brachionidium folsomii but the lip of the latter is geniculate with a deflexed base and incurved lateral angles." Luer 1995
