Water enough to keep the roots from drying but don’t let it sit in water.

Zygon: means yoked petal
Native to South American ( Venezuela, Peru, Brazil ) rain forests about half way up the mountains, usually in recently disturbed locations that have an increase in light.
The flowers are often green with purple splotches. The lip usually has white stripes.The pseudobulbs tends to be rounder than most
