require a liberal supply of water during the growing and 

 flowering season. During the time they are making vigorous 

 growth, they may be syringed twice a day, or even oftener. 

 This is far better than using a watering-pot, as it serves the 

 purpose of a shower of rain, and helps to keep the red spider 

 from the leaves — an insect which is very injurious to these 

 plants. Green fly is also very troublesome ; it should be 

 kept under by washing them with a sponge and cold water. 

 The plants rest after the flowering season is over, and 

 during this time less moisture is required. It is a good plan, 

 after the growing and flowering seasons are over, to place the 

 plants in rather a shady part of the garden, and syringe them 

 occasionally — not keeping them too moist — as they may pro- 

 bably perish if allowed to get dry at any time. The most 

 suitable time for potting them is just as they are beginning to 

 make roots, which is usually in the months of January and 

 February. They are easily propagated, as they throw up 

 suckers in abundance. These should be left till well rooted, 

 and then be taken ofi" and potted in the material recommended 

 for established plants ; after which they must be kept moist, 

 and in the shade, until they make fresh roots. When they 

 become established, place them near the light, and apply more 

 water to the roots. What they principally require is coolness 

 and moisture at the root, and a good season of growth during 

 the winter months. C. Leach, Esq., of Clapham Park, grows 

 the D. grandiflora in cold pits, and we never saw any shown 

 in better condition ; these plants have been thus grown by 

 him for years. 



D. Barellii. — This is a showy and handsome species in the 

 way of D. grandiflora. The flowers are orange scarlet, lip a 

 lighter shade of the same colour with crimson veins. It 

 should receive the same treatment as D. grandiflora,
