Caladinm continued. 



freer and more vigorous growth than if otherwise treated. 

 Water sparingly at first, but as soon as the leaves expand, 

 increase the supply ; and, when the pots are well filled with 

 roots, apply clear liquid manure at every other time of 

 watering. As the season advances, the temperature and 

 humidity of the house should be increased. During bright 

 sunshine, Caladinms should be slightly shaded for a few 

 hours in the middle of the day, with some thin material, 

 just to break the fierceness of the sun's rays ; but the more 

 they are exposed to the light at other times during growth, 

 the brighter, richer, and more beautiful will the foliage 

 be. As soon as the plants have attained a good size, 

 some of them should be placed in the coolest part of the 

 house, and partially hardened off ; they may then be taken 

 to the conservatory, allowing them a situation free from 

 currents of cold air, and giving water only when really 

 necessary. They may remain here for some time, but 

 care must be taken to return them to the stove before 

 they suffer from cold. 



Small neatly grown specimens make beautiful orna- 

 ments for table decoration, and their suitability for exhibi- 

 tion purposes is well known, and largely taken advantage 

 of. Towards autumn, and as the foliage begins to fade, the 

 supply of water should be gradually lessened, until all the 

 leaves die down ; the pots should then be placed under the 

 stage in the stove, where they can be looked to now and 

 then, and a little water given if required. By no means 

 allow the tubers to get dried up, as is often done ; for, if 

 so, they will frequently rot away inside ; whereas, kept in 

 a semi-moist condition, even the most delicate can be pre- 

 served. In this state, they may remain until the follow- 

 ing season. Caladinms will not endure a very low tem- 

 perature ; from 55deg. to 60deg. is as low as they can be 

 safely kept. Very few of those known as " true species " 

 are grown, being superseded, for general decorative pur- 

 poses, by the numerous hybrids which have been raised of 

 late, principally from C. bisolor.
