 baskets. They also require an abundance of water

 only enough water is applied to prevent the pseudo- 

 bulbs from drying.

 abundance of overhead water during active growth.

 in the summer; otherwise, the culture is the same 

 as for Cattleya. 



Culture of Odontoglossum

 and a cool moist temperature during the summer. 

 They are grown in pots or baskets filled with soil 

 made of equal parts peat, live sphagnum moss, and 

 osmunda fiber.
