The members of the genus Trichoglottis can be divided into two groups: those with inflorescences much shorter than the leaves, and those with inflorescences at least as long as the leaves. The latter group is often considered to represent a separate genus, called Staurochilus. In both groups, however, the structure of the flowers is very similar, and there seems to be little justification in keeping them apart. The lip varies from shallowly concave at the base to distinctly spurred; in each case an erect, hairy lamella is found at the base of the lip. Although little used in hybridisation, this genus is frequently cultivated by amateurs.
