Giant boat-lip orchid

This common epiphytic or lithophytic orchid grows in rainforest or damp forests around Brisbane. It typically grows in hollow limbs or tree stumps, but is often found growing on the ground.

The grass like leaves grow to 90 cm by 4 cm from the large pseudobulbs. The flower stems grow to 80 cm with up to 70 flowers about 25 mm across. 

The only similar orchid is Cymbidium suave which can be easily distinguished by its lack of pseudobulbs.
