Calydorea amabilis

Calydorea amabilis 

Like some other tropical irids, the flowers of this species last only a few hours. In this case those few hours are in the morning. And the flowers are about the diameter of a quarter. And the colors are very soft. And if there is a fragrance, I have not noticed it. So, let's add it up: fleeting flowers, small size, inconspicuous color,  no scent - a plant designed to be overlooked?
On the other hand, it does take care of itself. Other than bringing it in for the winter, it's carefree. And my single plant does set abundant seed freely.
At first glance this looks a lot like Iris dichotoma.
