About
Tropical epiphytic orchid with elliptic, dark green, leathery leaves. Downwards facing, complex flowers are pollinated by male Euglossine bees (also called Orchid Bees) that confuse the flowers for females. This orchid has evolved in an unique way - to mimic and deceive its pollinator. Scented flowers are short-lived, lasting only 2 or 3 days, but large plant produces numerous racemes that flower in succession. Pendant flowers stems emerge from the basket base in summer and carry up to 10 yellow-orange, lightly spotted flowers. Each pseudobulb carries one large, 40cm long and 12cm broad leaf. The plant produces a clump of pseudobulbs (thickened stem of ovoid shape on the base of each growth), which serve as a storage organ for water and nutrients.
About the genus
A genus of the orchid family from Central and South America. This genus of epiphytic orchids is characteristic for its complex flowers. Flowers grow downwards and are strongly fragrant, but fairy short-lived. Ribbed, ovoid pseudobulbs form a tight clump, with each carrying one large, stemmed leaf

Care notes
CultivationGrow in a hanging basket lined with moss, in an open, bark-based orchid compost with addition of perlite and sphagnum moss. Provide enough bright filtered light, but keep away from direct sunlight or a heating source. May be grown in intermediate to warm conditions with temperatures between 12-30 °C. Seasonal and daily fluctuation of temperatures encourage flowering. Average humidity of 50-70% is sufficient and watering should be frequent enough during growing season (approximately once per week), with being reduced by half during winter months. Large specimens produce best flowering, however it is desirable to repot plants every few years to avoid stale, disintegrated potting mix.
PruningNo pruning required. Remove spent flowers after flowering.
PropagationPropagation by seed is only possible in a controlled laboratory environment. Mature plants may be divided when the plant overgrows its container. Each division should have at least 3 older pseudobulbs with a sufficient amount of stored energy and water, to support new growth and reduce stress after repotting.
Pest resistanceGenerally pest-free, but may be susceptible to scale insects or mealybugs
Disease resistanceGenerally disease-free. Insufficient ventilation combined with overhead watering may cause bacterial spots on the leaves.
