One species P imraei, has no visible annulus or it is entirely absent. The sepals are glabrous externally but are often pubescent within. The lateral sepals are connate at least to the middle.

The column is elongate and amy or may not have teeth or wings and often but not always cover the anther. The anther and the stigma are always ventral.
