About this species

During the warmer months, Bulbophyllum macranthum bears large, solitary flowers with an exotic, sweet perfume. The bright flowers are somewhat variable in colour and are unusual in that they are held upside-down in comparison to the majority of orchids. Instead of being resupinate (twisted so that the lip is borne upside-down), the lip is held at the top of the flower (non-resupinate).

Bulbophyllum macranthum belongs to the Sestochilos section of Bulbophyllum, the largest orchid genus in the world. Section Sestochilos contains about 23 species, most of which have one-flowered inflorescences and rather showy flowers with relatively large petals; species in this section often have thick, long-creeping rhizomes.
