Note.
Our description is based on Pearce and Cribb (2001) and an image of the holotype, which is apparently the only collection made of this species so far. Herminium albosanguineum is similar to H. albomarginatum , but differs in having a fewer-flowered inflorescence, white sepals, red petals and lip. It is also similar to H. albovirens ; see under that species for a comparison.
