I purchased this plant as Trisetella sororia, which it most definitely is not. I believe instead that it is Trisetella klingeri, from Ecuador. The plant is tiny, like all Trisetellas, only about 3-4 cm tall, and the flowers, born on 6 cm spikes are about 1 cm in size. This plant was at one time classified as a Masdevallia, but was separated into its own genus in the 1980's. It is named after an American orchidist.
