Macroclinium aurorae

This tiny orchid is from Peru and is named for a Peruvian orchid enthusiast, Mrs. Aurora Bennett.  The plant is a small fan of thickened leaves less than 3/4 inch tall with a pendant spike of flowers which are each nearly 3/4 inch tall.  The flowers, as can be seen in the photos, form a kind of spherical starburst.  It related to Oncidium.
