The hollow pouch is elongated and up to 12 cm long. The sac is filled with many stomata on the inner surface and has an opening at the upper end near the stalk.
Organic debris and rainwater may be supplemented with secreted fluids to accumulate in the cavity of the bag and over time provide a source of nutrients that the plant uses by growing roots indoors. The main flower is yellow and striped with green. The fruit consists of a pair of horn-shaped follicles. The seeds have fine hairs at one end.
