Genus: Brassia, common name, "Spider Orchids". Genus consists of about 30 species from South America. Named in honor of William Brass, a 19th-century British botanical illustrator, these orchids grow in the wet forests of tropical Central and South America, but are also easily cultivated. Many species in the genus Brassia are pollinated by parasitic wasps, which normally lay their eggs on spiders. The patterns and structure of Brassia orchids resemble a spider in its web enough to encourage these wasps to lay their eggs in the plants' blossoms and in doing so pollinate them.

This one appears to be Brassia Rex "Sakata".
