CALLUNA. (LING. HEATHER.) 



A beautiful little hardy shrub, so well known as 

 to need no description. It prefers a peaty soil, but 

 can be grown in ordinary garden soil. The type, 

 vulgaris, is surpassed in beauty by the varieties ; 

 the white forms being favourites. Harnraondi and 

 Serlei are the best of these. Alportii and carnea 

 are good coloured varieties ; Foxii and pygmjea are

valued for their dwarf habit; flore-pleno for its 

 double flowers ; and argentea, aurea, and cuprea 

 for the colour of their foliage. All are propagated 

 by cuttings. Calluna is generally catalogued by 

 nurserymen with Erica. 



CALLUS. 



This name is applied to a corky swelling or out- 

 growth from the base of cuttings after they have 

 been inserted in soil for some time. If a Pelar- 

 gonium cutting is examined after it has begun to 

 callus, the cushion of tissue will be found to arise 

 at the junction of the bark and the wood ; in other 

 words, it arises from the cambium layer, and is a 

 sign that the cutting is going to form roots. The 

 latter arise from the inner side of the cambium 

 layer, and push or pierce their way through the 

 callus. The same process may be seen where 

 branches have been cut off trees, the callus being 

 the method of covering or healing the wound. 



CALOCHILUS. 



Terrestrial Orchids (ord. Orchidacese), whose 

 chief beauty resides in the lip, which is densely 

 fringed on the upper surface. The rootstock is

tuberous. Increase is obtained by removing the 

 offsets, or by dividing the clumps of tubers. 

 Fibrous loam and turfy peat, witli sand, will suit 

 them. They require a greenhouse temperature, 

 with an increase of heat when about to bloom, and 

 again when making their growth, at which time 

 plenty of water should be given.

CALOCHORTUS. (MABIPOSA LILY.) 



Description. Exquisitely beautiful bulbous 

 plants (ord. Liliaceoe) of great value for the garden, 

 or for frame cultivation. Many of the flowers are 

 beautifully marked, and it may be safely said that 

 all are worthy of cultivation. 



Propagation. By seeds sown in pans, and the 

 plants grown in a cool house, planting out the 

 seedlings the third year. Also by offsets, removed 

 when the parent plants are at rest, and by the 

 small bulbs some produce on the stern. 



Soil. A light, peaty soil, well drained, will suit 

 the Calochorti, but it is preferable to make up a 

 compost of sand, leaf soil, and road grit. 



Other Cultural Points. Plant from the middle 

 of September to the end of November, 3" deep, and 

 the same distance apart, in raised beds of the soil

recommended above. A sunny place should gener- 

 ally be chosen, where the plants can be shaded 

 when in bloom. Cover the surface with Bracken,
