Here is something that might help... I hope...
•Pseudobulbs of Catasetum flowers are cigar-shaped and clustered.
•After the leaves drop off, catasetum's pseudobulb become spiny.
•Presence of Unisexual flowers, is the exceptional feature of Orchids and so also with catasetums.
•Male catasetums are produced in shaded regions and female catasetum flowers are produced in high light.
•Catasetums are deciduous flowering plants which become dormant in winter.
•During dormancy, Catasetums can be removed from the orchid house and kept dry until spring.
•Plant Catasetums in a container which encourages good drainage conditions.
•Repotting should ideally be done when the plants are growing, usually in spring.
•Water the plants heavily as plant growth becomes more heavier, producing more roots to satisfy the plants' needs.
•Catasetums need Fertilizers almost once every week.
•Dry out the catasetum plant after flowering and water it to prevent shrivelling of the bulbs.
•Water the plant until the new lead and roots start to appear.
•Stake the spikes of 4-6 inch, which is helpful in encouraging good flower arrangement on the developing inflorescence of a catasetum.
