"A minute creeping specie that is related to B cogniauxiana but twice smaller. the tiny leaves are broadly elliptical, the flowers however are only slightly smaller than those of B cogniauxiana and differ ony in monor details of the lip. Both have shallo articulations with a bulbous tip of the column foot but the pair of calli on the center of the disc are more prominent in B dusenii." Luer 2000
