Note: some Cohniella species, in the past, were originally described as Dendrobium and later were recombined into Cymbidium, Lophiaris and Epidendrum.

Despite some authors, based in molecular studies, recently recombined various genera derived from Oncidium sections like Cebolletae, Plurituberculata and Pulvinata subordinating it to Trichocentrum we agree that morphological affinity for identification purposes are better represented accepting other genera nomenclature to subordinate this recent combinations.

Thus we are adopting here the following nomenclature in spite of Trichocentrum phylogenetic affinity of species that have been moved to traditional Trichocentrum:

1. Trichocentrum for traditional species that aren't recombined recently. This species have plain leaves and apparent conspicuous calcar (nectary).

2. Cohniella for those species who derived from classical Oncidium sect. Cebolletae Lindl. This species have speckled terete leaves without apparent calcar.

3. Lophiaris for those species who derived from Oncidium sect. Plurituberculata Lindl. This species have speckled plain leaves without apparent calcar.

4. Grandiphyllum for those species who derived from Oncidium sect. Pulvinata Lindl. and those who haven't recombined into Trichocentrum recently like Oncidium sect. Paucituberculata Lindl. pro parte. This species have large or short plain no speckled leaves like "mule ear" and they have usually trichomaceous elaiophores on flower's lip without apparent calcar.
