Picked up this little NOID years ago at Hausermann’s Orchid show in Chicago. Maybe from there or Fox Valley Orchids; unsure. Lost his tag, so seeking help in ID. He’s surviving, but not growing; never bloomed. Sits in north window, watered weekly with fish tank water and occasional fertilization. Leaves smooth, slightly shiny. Has never pushed out another leaf in all the time I’ve had him?! This one a slightly darker green leaves than my others with a silvery netting overlay. Undersides of leaves are a greenish purple. Thinking if I had an idea of what variety he is I could adjust growing conditions and (at least) get a third leaf? Thanks!
