40 Annals of Horticulture. 



pink, with delicate yellow center ; Sabine, white, with a pale 

 yellow center ; Mrs. Gane, an early white ; Mrs. R. Owen, also 

 white and of good size ; Nelson, a large dull red ; Mrs. M. 

 Russell, yellow, and Bessie Pitcher, rose with a lighter center, 

 seem desirable and worthy of more general cultivation ; some 

 of them when grown for single flowers make fine specimens 

 and give a pleasing variety. Something too should be said 

 for the Pompons, but so few are to be found that a select list 

 would be hard to make. It seems a pity that such an interest- 

 ing class should be so entirely overshadowed by the Japanese ; 

 the profusion of flowers and their bright and natty appear- 

 ance more than make up for what is lacking in size. It is 

 not profitable to extend any list of these flowers, although 

 it is difficult to pass by many favorites ; every gardener 

 will have his own successes and failures. What can be well 

 grown in one place is not always satisfactory in another. 



' ' There remains to be said a few words about insects. With 

 the more extensive and elaborate cultivation, as would be 

 expected, there have appeared several new pests, the most 

 injurious of which attack the plant while growing out-doors, 

 both in field culture and in pots. In many places, the plants 

 have been greatly damaged, and in some cases practically 

 destroyed during the past season by what appeared to be 

 a very small fly. The trouble begins soon after the plants 

 have been put in their summer quarters, but does not become 

 evident until they have attained some size ; then it will be 

 seen that there is a marked failure in the growing points ; 

 growth is stopped, and when new growth begins, it is again 

 stopped ; and so on until the vigor of the plant is destroyed. 

 This is probably caused by a leaf-hopper, but it is quite possible 

 that other insects may help. These insects are described with 

 care, and figured by J. G. Jack, of the Arnold Arboretum, in 

 Garden and Forest, Vol. iii. No. 133, page 439, and remedies 

 are suggested. It is doubtful whether this trouble is wide- 

 spread, but when it comes it seems to stay and increase. 

 When plants are grown under glass, the insects do not 

 appear in sufficient numbers to do harm, and it is certainly a 

 cure to lift and bring in the plants. Fumigation will drive 

 the insects from the greenhouse if it does not destroy them. 

 The mere work of lifting and potting in some cases seems to 

 drive them away. Mr. Jack advises spraying with a kerosene
