Vanda coerulescens

[Mokeck]

When you have 100+ orchids placed in trees around a sprawling yard that looks like a jungle, it's not until some are in full bloom before you notice them. This one is small, a single growth with one spike. The flowers are about 2-3 cm wide so it's easily out of sight until it blooms. Some of this species are fragrant but not this one. No matter, the well-spaced flowers look like swans to me.
