This pendant orchid used to be Lepanthes nummularia, but has been reclassified to Andinia. It seems to be pretty hardy, and has been slowly growing for a few years. The room it’s in stays between 60-80F depending on the time of year. It’s being grown on a narrow branch in medium light.
This particular Lepanthes species occurred in small numbers at about 1000 meters in elevation. After taking a few photographs I could see the petals clearer, which looked to me like hairy arms resting on wide hips, impatiently waiting for me to take a photo and move on.
