The plant generally ltegins to grow after tlie flowers have fallen, and it will sometime* make two 

 growths in one season, and often two from cncli bull) if the plant is vigorous; but one growth is belter limn 

 two if it be strong and licaHliy, a* it will flower liner. After the growth is completed, a good season of rest 

 muat be afforded, by giving less water at the roota. Tho roots must, however, new he kept in too diy a 

 state, as the plant will then shrivel, which is dangerous and often conducive of an unhealthy condition of 

 growth. They should have just water enough to keep the leaves and bulbs plum]). The plant forms its 

 bulbs in summer and autumn, and during this time it must have a liberal supply of moisture. It should tic 

 watered about two or three times a week, so as to keep the soil moist; but, on the other hand, it is never to 

 be kept wet, for, as already mentioned, it is in its native habitat found growing on the branched of trees, and 

 no plants that naturally grow on trees like too much water at the roots: they gel heavy rains at times, 

 but l>eing so thoroughly elevated, tho water passes off quickly, and besides they arc exposed to a free current 

 of air. When, therefore, they come to be confined in our hothouses, tliey require moisture to be supplied 

 with great care. After a hot sunny day more moisture is required, and this is best applied by pouring 

 water on the tables and pathways; but if the weather be dull outride les* of it is required. The condition 

 of the weather should servo as a guide to all Orchid cultivators, for the changes in the weather outside the 

 bouse should make a material difference in their treatment inside. 



During the season of active growth the temperature should range from 70° to 85 by day, and from 

 G5* to 75" by night During winter from 55° to GO* is sufficient ; and in the Spring this temperature should 

 be increased, so as to range from GO* to G5* by night. In potting, pots of moderate size ought to be used, and 

 these should be filled up with potsherds to within two inches of the top, mid die remaining space made up with 

 good fibrous peat, mixed with a little charcoal to keep it open. The roots delight to cling to the charcoal. 

 Above the rim fdl in peat to the height of three inches, and on the lop of this place the plant, and secure 

 it firmly by placing peat over the roots. The best time to pot is just after blooming; and this is also 

 the best time for propagating the plant, if required. Tins latter is very easily done, as the plant is of free 

 growth, and will divide well- The best way is to cut between the bulbs, leaving one or two older bulbs to 

 each leading shoot These divisions should be potted into small [>ots, and must not bo allowed to llowcr until 

 they have become well established t for it is such a free-blooming plant that it will often flower and exhaust 

 itself before it has had time to become sufficiently rooted. 



These Driehofitiiua arc not like many other Orchids, subject to insect attacks, but sometimes they 



become infested with white scale or thrip, both of which are easily cleaned off with a sponge and pure water. 



If however the plants are watched, they may be generally kept free from such (jests. Tobacco-smoke affords 



the best means of keeping down the tlirip, the house being fumigated two or three times in a week till it is 



destroyed* It is desirable not to have loo much heat in the house when this operation is performed* and 

 not to apply the fumes too strong.
