ORIGIN Catasetum is a genus of some 80 - 120 species which are found from Mexico in Central America to as far south as Argentina in South America.
	DESCRIPTION Most catasetums have fleshy pseudobulbs with 8 - 12 thin, pleated, pointed leaves; and display a complex pollen ejection mechanism.The flowers of Ctsm. integerrimum are yellowish green to deep green, sometimes spotted with maroon. The lip is at the top and is shaped like a hood giving the flower a monk-like look. This species flowers from April to November.
	LIGHT REQUIREMENTS All catasetums like a high amount of light. Male flowers can be produced by providing some shade, female flowers by allowing the plant to receive direct sun or bright unshaded light.
	TEMPERATURE These plants are intermediate to warm growers. They should also have plenty of fresh air ventilation. Summer day temperatures should be from 80 - 95 F with night temperatures of 60 - 65 F. The winter temperatures should be cooler: 75 - 85 F in the daytime and to as low as 55 F at night.
	MOISTURE & HUMIDITY All catasetums need plenty of moisture and humidity during their growth period. Provide high humidity of 80% or greater throughout the year. Water often during the active growth period and make sure it drains through the medium so the roots do not sit in water. When the leaves fall in late autumn, decrease watering to almost none. Resume watering when new spring growths reach about 1/2 inch tall.
	FERTILIZING Catasetums are heavy feeders so feed with your usual fertilizer mix (1/2 directed strength) with every watering. Withhold feedings in the winter rest period and resume when new growth starts in the spring.
	POTTING MEDIUM Grow these plants in well drained pots or hang in baskets of NZ sphagnum moss. Use a freely-draining bark mix for potted plants. Repotting yearly when new growth begins is strongly recommended.
