Bulbophyllum fletcherianum, the tongue orchid, is a rare orchid native to southern New Guinea. It prefers sunny rock outcrops or mossy tree branches, but besides being lithophytic or epiphytic, it can also be pseudo-terrestrial.
Bulbophyllum fletcherianum is one of the largest species of orchid in the world, with leaves growing to almost 1.8 meters (6 feet) or even 2.1 meters (7 feet) with a width of up to 30 cm (one foot) from a pseudobulb the size of an orange. The leaf is pendant and can be green, or purple with green edges, and is the largest leaf of any known orchid. It is allied to other large orchid species such as B. phalaenopsis and B. macrobulbon. The flowers are maroon and spike-shaped, and release an over-powering aroma which attracts blowflies and carrion beetles for pollination. The fragrance of these flowers, like those of B. beccarii, have been compared to a whole herd of dead elephants.
