This is Onc. Sharry Baby 'Short Sharry', my favorite of the five different clones I have grown.
It has been growing in water culture for 3 years and this is one of 4 divisions since. It has grown faster than in any other medium I had tried in the past 20+ years and the flowers last longer. This is one plant I keep in water culture permanently because I can keep it compact when not in bloom since the roots are growing dense and short, as you can see from the close-up picture, and the plant remains easy to lift. The older I get the more important this has become. Division is also easy. One cut and I can put the divisions in semi-hydro and give them away.
Right now there is a sibling about to bloom in South America in the yard of a friend who has many in pots and wild orchids all over her trees but wanted this one.
