448 THE GARDENER. [Oct. 



best way to get rid of this insect, or to keep it within bounds. Syringing 

 wall-trees in summer should always be practised, for it is good for washing ofT 

 dust, red-spider, and other things which militate against the trees' health. 

 Scale sometimes attacks wall-trees in warm positions. The easiest way to get 

 rid of it is to syringe the trees thoroughly in winter, with water mixed with a 

 sixtieth part of parafFiii-oil. It is not likely to be troublesome in cold localities. 

 Sometimes different kinds of caterpillar attack the leaves of this and other 

 fruit-trees. Handpicking is the best cure. A. H. H, 



H^MAWTHUS CINWABAHINUM AND H. KALBREYERI. 



H.EMANTHUS is a genus of Amaryllidaceae, and these two are very 

 striking plants. They were introduced from the west coast of Africa, 

 and are evergreen bulbous plants, the foliage of which, in general 

 appearance, resembles that of Eucharis amazonica, and they throw 

 up their flower-scapes in very much the same way as that popular 

 plant. They produce dense globular heads of bloom on strong stems : 

 good bulbs of cinnabarinum have heads 6 inches in diameter, and 

 Kalbreyeri are still larger. The colour of cinnabarinum is a most bril- 

 liant cinnabar scarlet, tinted with carmine, resembling the colouring of 

 Masdevallia Veitchii. The anthers are of a brilliant yellow, which 

 add to its effective appearance. Kalbreyeri, of more recent introduc- 

 tion, produces splendid heads of bloom of vermilion-red colour, on 

 very stout stems, that are spotted with bright claret. 



These two plants should be in every plant-stove. Their flowers are 

 very lasting, and keep fresh for a long time when cut and put in water. 

 They are of easy culture, and, like most bulbous plants, should have 

 small pots rather than otherwise. They do not require any peculiar 

 treatment to make them produce their blooms annually. If grown in 

 loam, a little rotten manure, and a dash of sand, not too far from the 

 glass, and their foliage kept clean, these two Hsemanthus will amply 

 repay, with their long-lasting and strikingly brilliant heads of bloom, 

 any trouble bestowed on them. R. M'C. 



WINTER-FLOWERING PLANTS. 



The time of year is again at hand when all winter-flowering plants will 

 or should be placed in their winter quarters. The nights have turned 

 cold rather earlier than usual in this locality, and plants have in con- 

 sequence been placed where they are safe. It frequently happens that 

 when housing time arrives we are not ready for it, and plants are 

 often checked while houses are being prepared for their reception. 

 Sooner than run the risk of failure in this respect, it is better to 

 house the plants, and then wash and do the necessary cleaning to the 

 houses afterwards. Great difficulty is often experienced in finding
