Corynella 



( 242 ) 



Cosmibuena 



fruits are named. (Sec also NUTS.) They avo prop- 

 agated by seeds (Nuts), la.vers, suckers, and 

 grafting, the first for the reproduction of the 

 species, and the other methods for multiplying the 

 varieties. They will grow in any friable soil, fairly 

 moist but well' drained, a hillside for preference; 

 but the land should be fairly fertile for fruiting 

 plantations.

 agated by cuttings of half-mature side shoots in 

 sand under a bell-glass, or in a propagating case.

 plenty o sharp sand, MI it them.

CORYNEUM. (GUMMING FUNGUS.) 

 Stone fruits that is, Cherries, Plums, Peaches, 

 and their allies are liable to gumming, otherwise 

 termed guinmosis. This is often caused by a fungus 

 named Coryneum Beijerinckii, the mycelium of 

 which penetrates the outer tissues of the host 

 plant that is, the cambium region and sets up a 

 ferment, whereby the protoplasm of the growing- 

 cells acquires new properties. The young cells 

 (parenchyma) in turn secrete the ferment, with the 

 result that their walls and contents nre more or 

 less changed to gum. This disease can be com- 

 municated to healthy trees, and only requires the 

 bark to be injured or broken by frost after 

 insufficient ripening of the wood, by accidental 

 breakages, and by injudicious pruning. Prevention 

 is better than remedy, and gardeners should avoid 

 excessive cutting by pinching young shoots in 

 summer where their presence . is unnecessary. 

 Lifting and root pruning, as well as planting in 

 poorer soil, are means whereby excessive growth 

 may be checked or prevented, so that the wood 

 will ripen better. 



CORYNOCARPUS. 



This New Zealand tree -(ord. Anacardiaceae) is 

 evergreen, and should be grown in the greenhouse 

 in rich, loamy, well-drained soil. It may be prop- 

 agated by layers or cuttings in light scil.

 cultivation.

CORYNOSTYLIS. 



A genus (ord. Violaritii') of stove perennial 

 climbers that flourish in lilirous loam, peat, and 

 coarse sand. They may be propagated by cuttings 

 in very sandy soil under a bell-glass, in gentle 

 bottom heat. 



Principal Species :

CORYPHA. 



These are the well-known Fan Palms (ord. 

 Palmse). They attain to a considerable height in 

 their native places. They grow best in the stove; 

 in a mellow, sandy loam, and may be raised from 

 seeds. The leaves grow upon the summit of tho 

 plant, and are handsome when clean and well 

 grown.

These small terrestrial Orchids (ord. Orchid- 

 acea>) are mostly found in Australia and New 

 Zealand, and may be grown in a greenhouse in a 

 mixture of peat, sand, and chopped sphagnum.

COSCINIUM. 



A stove climber (ord. Menispermacea:"). that, 

 hails from Ceylon, where it is accredited with 

 some medicinal virtues. It flourishes in peat and 

 loam, and may be raised from cuttings in sand 

 beneath a bell-glass over bottom heat.
