of Ceylon, and in the collection of His Grace the Duke of Northumberland, at 

 Sion-house, where it flowered in August, 1837. According to Dr. Blume, it 

 varies with white and pink flowers, and with more or less oblong coriaceous leaves. 

 It is easily cultivated. 



Dendrobium aureum, var. pallidum. Golden-flowered Dendrobium, pale 

 variety. Bot. Reg. 2 S. t. 20. This too is a pretty species, bearing white and 

 orange-tinted flowers. It is also a native of Ceylon, where it was found by Mr. 

 Macrae, growing upon trees near Nuera Ellia, flowering in January. It is not 

 uncommon in collections. The drawing was made from a specimen in the col- 

 lection of Messrs. Loddiges. It has a delicate scent, intermediate between violet 

 and primrose. It is as easily propagated as D. crumenatum. Bot. Reg. 



CALENDAR OF GARDENING OPERATIONS FOR MAY. 



The fires in the plant stoves may be discontinued if the weather prove mild 

 about the middle of this month. The stove should have air early, as soon as the 

 thermometer reaches about 75 degrees ; and by shutting up early in the after- 

 noon and sprinkling the floors, it will make a moist heat that ought to be suffi- 

 cient to keep the house up to 60 degrees in the morning. 



The time for planting out greenhouse and half-hardy plants into the open 

 ground is from the middle to the latter end of the month, being somewhat 

 earlier or later, according to the state of the weather. These and Dahlias ought 

 to be gradually hardened before planting out, by being placed in frames or pits 

 for a week or ten days previously, where the sashes can be drawn off during fine 

 weather. 



Transplant hardy and half-hardy annuals into their flowering stations, taking 

 • advantage of cloudy or showery weather for that purpose. 

 Ridge out Cucumbers for fruiting in the open ground. 



Attend to shifting Balsams, Cockscombs, and other tender annuals. These 

 ought to be finally got into their flowering pots by the middle of the month, that 

 they may be ready to be put into the greenhouse when the plants are turned out 

 of doors. 



Rose trees, when attacked by the green fly, ought to be watered with a 

 mixture of water and tobacco liquor in the evening. 



Look over the peach trees upon the walls, and pick off all blistered leaves as 

 they appear, and thin out the wood shoots so as to give strength to those wanted 

 to make wood for the next year's crop. 



Prepare beds of Neapolitan violets in a sheltered border of good soil. If 

 made of a size for covering with frames, they will flower fine during the ensuing 

 winter.
