St. Albans, in 1913, and our drawing was made when it 
flowered at Kew in June, 1916. Under cultivation, C. 
integerrima thrives well in a tropical house in a compost 
of fibrous peat and sphagnum. During its season of 
growth it requires a liberal supply of water, but when 
the growth has become fully matured all that is necessary 
is to supply moisture just sufficient to prevent the 
pseudobulbs from shrivelling.

in. long, 2-foliate. Leaves elliptic-lanceolate, acute or shortly acuminate,
