be necessary until young roots begin to push into 

 the soil. A light place near the glass in a moist 

 stove is required during' the growing season. 

 When the pots are filled with roots, manure water 

 must be given twice a week. When the " bulbs " 

 have attained to full size they should.be placed in 

 a cooler, drier house. The deciduous species re- 

 quire little or no water after the leaves begin to 

 turn yellow, until the flower spikes are several 

 inches long, providing the bulbs do not show signs 

 of shrivelling.

CALATHEA. 



Description. Ornamental - leaved herbaceous 

 plants (ord. Scitaminese), natives of tropical 

 America and the West Indies. The species are 

 numerous, and form dense masses with very short, 

 contracted stems, from which the large, often 

 prettily marked foliage and terminal spikes of 

 rather insignificant flowers spring. Many of the 

 species are often confused with the closely allied 

 genus Maranta, slight botanical differences only 

 dividing the two genera. The leaves of some 

 species are used for basket making in South 

 America. 



Propagation is easily performed when growth is 

 active by dividing the clumps, potting the pieces 

 in rich light soil, and placing them in a close and 

 warm propagating case until established. 



Soil. A light, loose compost is essential. This 

 may be obtained by mixing two parts of peat to 

 one part of loam and one of leaf mould, adding a 

 good proportion of silver sand and charcoal. 



Other Cultural Points. Shallow pans one-third 

 full of crocks are preferable to pots, and potting 

 must be light. If the plants can be planted out 

 on a rockery or rootery much better results will be 

 obtained. When growth is active, abundance of 

 water must be given, but it must always drain 

 away quickly, Calatheas being very impatient of 

 stagnant moisture. The warmest place in the 

 stove should be given them, and they should be 

 syringed several times a day, always keeping the 

 surrounding stage, paths, etc., damp. They should 

 never be subjected to very bright sunlight, as the 

 leaves are easily scorched. Replanting or potting 

 must be done annually.

Plants growing in borders may have a top-dressing 

 of light, rich soil annually. Liquid manure once a 

 week in summer heightens the colour of the leaves.

CALCAREOUS SOIL. 



Soil containing an abundance of chalk (carbonate 

 of lime). Chalk or lime is absolutely essential to 

 fertility, but the proportion may be too great. Soil 

 that is too heavily supplied with carbonate of lime 

 is not retentive of moisture, and the crops dry up 

 quickly in the summer. The sun's rays are reflected 

 so much that the soil remains unheated, and crops 

 are consequently late. Such soils are improved 

 by the addition of loam and animal manure. 



CALCEOLARIA. (SLIPPEE WORT.) 

 Description. A genus (ord. Scrophularinea:) 

 comprised of many distinct species, and numerous 

 hybrids and varieties, including annual and per- 

 ennial herbs, and dwarf shrubs. In gardens the 

 chief interest in the Calceolaria is centred in the 

 herbaceous varieties grown for greenhouse decora- 

 tion, and the shrubby evergreen sorts employed 

 for bedding, though some of the species are well 

 worth growing. Chiefly increased from cuttings.

Florists' or Herbaceous Calceolarias. Since culti- 

 vatorsand cross-breeders took up the improvement of 

 the herbaceous greenhouse Calceolaria great strides 

 have been made, till at the present time there are 

 numerous strains and varieties which are nearly 

 perfect in the size, form, and colour of the flowers, 

 the plants also being of dwarf, compact habit. 



Propagation. From seeds sown in July and 

 August. Calceolaria seed is very fine, and requires
