are the tallest in the world, 400-500 ft. high. The best-known kinds are 

 globulus, the "Blue Gum Tree", with large grey-green leaves. It is easily 

 raised from seeds in a warm greenhouse, and is much used for subtropical 

 bedding in summer. E. citriodora is a smaller-growing kind remarkable 

 for its delicious lemon scent, almost exactly like that of the Lemon-scented 

 Verbena (see p. 125). A few kinds are grown in the open in the mildest 

 parts of the kingdom, one of the best for this purpose being urnigera, 

 which has attained a height of 80 ft. in places. 



Eucharis grandiflora (amazonica). This fine Colombian bulbous plant 

 is still valued as a market crop. It flourishes in rich and rather heavy 



loam with a little well -decayed 

 manure or leaf mould and sand. 

 Stove treatment is necessary, and 

 plenty of water during growth 

 and frequent syringings to keep 

 the foliage clean. When coming 

 into bloom a little weak liquid- 

 manure water may be given occa- 

 sionally. The pure-white flowers 

 are packed in shallow boxes in 

 cotton wool, about two dozen 

 flowers to a box, prices ranging 

 from Is. to 10s. per dozen accor- 

 ding to circumstances during the 

 winter months. When several 

 bulbs are placed in large pots or 

 tubs, they grow well for several 

 years without repotting, although 

 they receive, perhaps, an annual 

 topdressing. To keep the plants 

 free from Mealy Bug, scale, and 

 Thrips, the syringe should be freely 

 used, with nicotine or quassia solutions occasionally. Sometimes the mite 

 is troublesome, perhaps owing to too high a temperature, and badly infested 

 bulbs should be burned. Others may be dipped in a strong solution of 

 permanganate of potash. Other species of Eucharis are Bakeriana, 

 Mastersi, Sanderiana, Lowi, all with white flowers but not so valuable 

 as E. grandiflora (fig. 280). 



Eupatorium. These are easily grown Composites with Ageratum- 

 like flowers, white or reddish purple. They are raised from cuttings in 

 spring, and require greenhouse treatment in winter. The best kinds are 

 atrorubens, riparium, trapezoideum, &c. 



Eurya latifolia variegata. A beautiful Japanese greenhouse shrub 

 of the Camellia family, with oblong lance-shaped leaves variegated with 

 creamy yellow. As it can only be raised from cuttings of the young 

 shoots, and is not a particularly rapid grower, its trade is somewhat
