Pterygodium flanaganii flower

A Pterygodium flanaganii flower has a curiously pointed, purple-striped, erect lip tip, here lemon-yellow in its lower part.

Some of the Pterygodium species transferred from Corycium have lips with oblong limbs. The lip is fused at its base to the gynostemium or column of the flower where a complex arrangement of male and female floral parts are compactly together (Leistner, (Ed.), 2000; iNaturalist; http://www.africanorchids.dk).
