CINERARIAS AND CALCEOLARIAS. 131 



leaf, and, increasing very rapidly, will do considerable injury 

 before its presence is discovered ; therefore we must examine the 

 underside of the leaves frequently. The strewing of chopped 

 tobacco stems in quantities around the pots is the best way to 

 ward off this enemy. Calceolarias require an abundance of water 

 until well grown ; but as little moisture as possible should be 

 tolerated on the benches, when they are in full flower, otherwise 

 the flowers will get spotted very quickly. Shading is very 

 necessary when they are in flower, their beauty being thereby 

 preserved to double the time it would otherwise continue. 



A vast deal more could be said in regard to cultural and other 

 details in connection with these two plants, but in view of your 

 possible weariness over the subject, I deem it best to stop. 



Discussion. 



Mr. Finlayson brought with him several cineraria plants in pots. 

 Some of them had few, but rather long and straggling branches ; 

 they had been supplied with all needed plant food, water, heat, 

 light, and ventilation, and had been protected from all insect pests. 

 These plants, he said, showed their natural habit of growth, as 

 they had not been nipped, cut back, or otherwise pruned. He 

 then brought forward other plants, which he said were of the same 

 age as those first shown, and had received the same treatment in 

 all respects mentioned, except that these had been judiciously 

 nipped early, and whenever it was judged necessary. This treat- 

 ment caused them to throw out more branches, which were shorter 

 than those on the nature-trained plants, but were more stocky, 

 and the plants were more symmetrical. They would also produce 

 more flowers than could be grown on the other plants. He next 

 showed a plant in bloom, saying that it had been nipped back 

 twice, which made it a shapely and good plant, and that the variety 

 was a good one. He called attention to another flower which 

 he condemned as a poor one, as he could see through it between the 

 petals. If the flowers are zoned, the zones should be well defined, 

 as all colors should be when more than one occurs in a flower. 

 One plant bore flowers in which the central or disk florets were 

 yellow, making a fine contrast with the crimson ray florets or 

 so-called petals. He said that the plants shown were all seedlings. 



In reply to a question as to the probable color of flowers on 

 seedlings from the seeds which grew in one capsule or seed
