only necessary when the snn is powerful ; at other times the plants should 

 receive all the light possible. During the season of active growth, water 

 should be copiously given, as well as an occasional syringing to keep the 

 bulbs plump and the foliage clean and healthy. As the season advances 

 towards autumn, the waterings must be diminished in frequency and 

 quantity till the plants are quite at rest, when only sufficient must be given 

 to keep the bulbs from shrinking. For large masses of C. eristata, 

 square teak baskets are often used, but perforated pans of about 6 inches 

 in depth are still better ; the drainage must be ample and free, and the 

 compost should consist of equal proportions of fibrous peat and chopped 

 sphagnum.

Sent by Cuming from Singapore, in 1840, to Messrs. Loddiges, in 



whose nursery it flowered for the first time in 1841. It is a 



pretty and distinct species, usually flowering in the month of 



August, but it is now rarely seen in British collections. We are 



indebted to Sir Trevor Lawrence, Bart., for materials for description.

 rhomboidal, inflated, as long as the pedicels and ovaries, dusky brown. 

 Flowers 2 — 2| inches in diameter; sepals and petals stellate, pale nankeen-
