A large number of crowded, yellowish green, non-resupinate flowers and many bracts are crowded along a brittle green flowering stem 150–350 mm (6–10 in) long.

The petals are a similar length but less than 1 mm (0.04 in) wide and curve downwards.

The labellum is horseshoe-shaped, about 5 mm (0.2 in) long and wide with between six and eight teeth near its tip.

[2][3][4] Crepidium flavovirens was first formally described in 1997 by David Jones and Mark Clements from a specimen collected near Malanda.
