vex surface wlif-ii finished. A plentiful supply of water 

 is essential at all seasons with copious syringing over 

 the foliage in l)right weather. The compost should 

 never be allowed to remain dry for a long time. 



r. tricolor and species like it grow very well among 

 foliage plants in the wanuhou.se, where their large 

 aerial root.s, which are freely emitted from the sides of 

 the stems, may ramble among the foliage and thereby 

 retain moisture a long time after syringing. A few 

 species, such as V. Aniesiana, V. cierulea and I'. 

 KlmhaUiana, with one or two other alpine species, re- 

 quire about ten degrees cooler temperature, but otlier- 

 wdse similar treatment to other species of the genus. 



.Stock is increased by remnviug a foot or more of the 

 leading growth with a shar]) knife, allowing several 

 routs to remain attached to each growth and basketing 

 them in the usual manner. These new pieces shoiild be 

 frequently .syriuged overhead until they become es- 

 tablished or they are likely to shrivel. The old stems 

 will nearly always send out several new growths. 



The principal insect enemies to Vandas are several 

 species of scale, whi<di breed fast in a dry atmosphere. 

 Th(n- r-an l)e kept in clieck by syringing with strong 

 toliacco water and by sponging the plants with a 20 

 per cent solutiitn of alcohol. jj j| Gkey
