Holcoglossum wangii - lovely white flowers have a pink blush.

 Holcoglossum wangii
     These are terete-leaved members of the Vanda tribe; best grown hanging. Native to sourthern China and Vietnam, it is a relatively new species in cultivation; first described in 1998. They have lovely white and purple flowers and are relatively small plants. We grow ours in intermediate conditions in our greenhouse, and they’d do well in a bright home window.
