It looks like this little Den has the mermaid genes too. The plant I bought this Spring fell apart and 1 part was put in S/H and this one in water culture.This one tried to bloom once before but I cut of all buds to encourage root growth, instead. As you can see it has beautiful new roots. The one in S/H is also growing OK but has not yet bloomed.
These flowers are only a little over 1/2 inch. Laura and Susanne has better photos of the flowers I link to below. It was because of Susanne photos that I learned about this great little bloomer in the first place.
Dendrobium oligophyllum
