In horn Dendrobium, the pseudobulbs are long, vertical canes of up to 1.5 m long, and are dangling pendulous rods in the nobile Dendrobium. The pseudobulbs are round and fat in Epidendrum and Spathoglottis , and flat and wrinkled in the mature bulbs of Oncidium. The pseudobulbs enables the orchid plants to withstand periods of drought. In some orchids, the pseudobulbs are buried deep in the ground and these plants are capable of surviving bush fires.
