Pterygodium magnum leaves

Pterygodium magnum bears many stem-sheathing leaves, broadly lance-shaped with down-curving margins. They taper and ascend, nearly erect, their tips pointed. The smooth blades are bright green to light green and hairless.

Leaf size reduces on the way up below the inflorescence, the lowest leaves about 25 cm long and 6 cm wide. Further up the leaves grade into the flower bracts, continuing without further reduction, if bract size is taken at open flowers in the spike. The bracts have flat surfaces, no marginal curvature (Manning, 2009; Pooley, 1998; iNaturalist; www.africanorchids.dk).
