Trisetella strumosa

Trisetella vittata is a tiny species from Ecuador.  All the species in this genus are small, are closely related to Masdevallia and were once classified with Masdevallia.  The plant is 3cm tall, the spikes 4cm long and the flowers 2.5cm from tip to tip.  The Trisetellas can be very difficult to identify but I am reasonably certain that this is Trisetella strumosa.
