 The labellum often has three lobes, in which case the side lobes are erect.The genus "Bryobium" was first formally described in 1836 by John Lindley who published the description in "A natural system of botany, or, A systematic view of the organization, natural affinities, and geographical distribution, of the whole vegetable kingdom".The name "Bryobium" is derived from the Ancient Greek words "bryon" meaning "moss" and "bios" meaning "life", an apparent reference to the habit of plants in this genus.
