BAKKERIA. 93 



Barkerias merit a place in every collection ; they are compact 

 growing, with upright slender bulbs, from the top of which 

 the numerous flower stems are produced. These plants suc- 

 ceed best on blocks of wood of a flat shape, so that the plants 

 can be tied on the top without any moss. They send out 

 their thick fleshy roots very freely, and will soon cling to the 

 blocks. They require to be grown in a cool-house, where 

 they can receive air every day during their season of growth. 

 The Mexican house will be the most suitable place for them, 

 and during their season of gi'owth a good supply of water — 

 twice a day in summer \d\\ not be too much for them ; but 

 dui'ing their season of rest very little water will sufiice — only 

 enough to keep their bulbs from shrivelling, about two or three 

 times a week. They should be suspended from the roof, near 

 the glass, where they can receive plenty of light, but not too 

 much sun.
