Taeniophyllum section Microtatorchis is an interesting section of very inconspicuous, often leafless orchids. The only character state that consistently separates this section from the other sections in Taeniophyllum is the presece of 2 pollinia in sect. Microtatorchis opposed to 4 in the latter. But most species of sect. Microtatorchis can easily be recognised by the inflorescences with an elongated rachis and the unusual floral bracts. Based on these bracts a subdivision in two sections was proposed by Schlechter (who else?):
1a. Floral bracts at the base without lateral projections == Genus Taeniophyllum sect. Microtatorchis subsect. Microtatorchis
1b. Floral bracts at the base with a lateral projection on each side == Taeniophyllum sect. Microtatorchis subsect. Geissanthera
