Oncidium varicosum Rogersii (see page 20) 
ONCIDIUM 
The Oncidiums are epiphytal Orchids of rare beauty, great variation in form and color, and are most 
prolific bloomers. Being natives of Mexico, Peru and the West Indies, they grow best in a temperature 
of from 50 to 55 degrees, and require plenty of air and moisture during growth. They may be grown in 
pots, pans or baskets, in a mixture of fibrous peat and sphagnum moss, and water must be given sparingly, 
but not withheld when showing flower-spike.
