It is generally grafted on to Cereus speciosissimus or Pereskia 

 aculeata, but those who have no stocks may insert cuttings. 

 The plants may be started in a warm greenhouse about mid- 

 winter, put into a cool house in summer, and given very little 

 water in winter.)

Caladium (cala-dium, from kaladion, a cup. Ord. Aroideae). 

 Except for the species argyrites, these are large-leaved, expansive 

 plants, and need large pots and a roomy 

 house to be done justice to. They are grown 

 entirely for their foliage, which is of great 

 size, borne shield-like on the stems so as to 

 show to advantage, and beautifully coloured. 

 They thrive best in a warm greenhouse in 

 which a humid atmosphere can be main- 

 tained. When huddled with other plants in A CALADIUM TUBER. 

 a small, dry house they soon lose their glow. x Point of division. 

 They form tubers, to which they die back 



in autumn, and from which they start afresh in winter or spring, 

 according to the heat available. Loam (3 parts), leaf mould (i part), 

 and sand suit them. They may be propagated by division while at 

 rest. Good varieties

Calanthe (calan-the, from kalos, beautiful, and anthos, flower. 

 Ord. Orchidaceae). The Calanthe is one of the most important of 

 all Orchids, because in addition to great beauty it has the advantage 

 of easy culture. It is what is called a " terrestrial " Orchid, that is, 

 it is grown in soil, not on blocks. Most of the species are evergreen, 

 but vestita is deciduous. One of the most valuable traits is the 

 long duration of the flowers, and fortunately this quality is retained
