most rapid and certain mode is by cuttings of the roots made in the fall, 

 kept in sand or moss over winter, then sown in diiHs early in spring. 

 The Chinese Qutnee ( 0. OhinenMs), is a very distinct species, bearing fruit 

 of an enormous size, but it is scarcely edible. Propagated by seed, or 

 grafting on stocks of the common Quince. 



Cyrilla. — A genus of two species of evergreen trees ; one species is 

 found in the Southern States, and the other in the West Indies and 

 South America. Readily propagated by seed and cuttiugs planted in the 

 open gi-ound in the South, or under glass in the North. 



Cytistis (Scotch Broom, Etc.). — A lai-ge genus of low, slender- 

 branched shrubs, bearing pea-shaped flowers. AH indigenous to the 

 Eastern Hemisphere, and many of the species are known under such 

 local names as Scotch Broom, Irish Broom, Spanish Broom, etc. The 

 hardy species are readily increased by seeds and layers, and the tender, 

 or those cultivated in the gieenhouse, by cuttings of the tender shoots 

 planted in close frames, or imder a belT glass. 



Dacrydium (Tear Tree). — A genus of handsome coniferous ever- 

 green trees, from New Zealand, Tasmania and New Caledonia. All 

 tender, except in the extreme South. Propagated by cuttings of the 

 matm-e twigs planted in sand imder glass, and by seed when it can be 

 obtained in a fresh state. 



Daphne (Spurge Laurel, Mezereon). — A highly-prized genus of low- 

 growing evergi-een and deciduous shrubs. Some of the species, like 

 the common Mezereon (i). mezereum), and the Garland Flower {B. 

 Cneorum), have been cultivated in this country for many yeai-s ; but 

 there are many other species, fuUy as hardy and valuable, that ai-e 

 rarely or never seen in our gardens. All thrive best in a half-shady 

 position, as the leaves are likely to bum during the hot weather in sum- 

 mer. Propagated by seed, when these can be obtai ned, by layers, cuttings 

 and grafting ; the stronger-growing being used as stocks. D. Oneorwn 

 is one of the very best of the hardy, low-gi-owing species for cultivation 

 in this country, and it may be increased by layers put down in spring, or 

 by cuttings of the ends of the young shoots obtained from young plants 

 forced in winter, or even from cuttings of the nearly matui'cd wood, it 

 taken off early in the fall and planted in a greenhouse where they wiU 

 receive only moderate heat— not much above fifty-five or sixty degrees 

 whUe the callus is forming. Veneer grafting on stocks gi-own m pots 

 is the best mode, as with other evergreen shrubs. 



Vartvinia. — Handsome evergreen shrubs, indigenous to Austraha 

 Flowers large and showy, either red or white, produced m tei-minal 

 fascicles. Cultivated in greenhouses in cold climates. Propagated by 

 cuttings of the young succulent roots placed in a close frame. 



Dasf/Uron (Lily Tree).— A genus of tall-growing dioecious ever- 

 green shrubs, natives of Mexico, and only hardy at the South, but 

 they are fine, showy plants, adapted to greenhouse culture, although.
