PROPAGATION OF PLANTS. 



Ceratiola.A low-growing evergreen shrub of the order Empetmcece, 

 native of South Carolina and Florida. Thrives in dry, sandy soil. Propa- 

 gated by seed or green cuttings under glass. 



Ceratonia (Carob Tree). An evergreen tree bearing pea-shaped 

 flowers, succeeded by long pods containing a sweet tasted, mucilaginous 

 ,ulp. Propagated by ripe wood cuttings planted in frames, or from 

 Jreshly gathered seed. 



Cerctdtphylliun. A slender, rapid-growing, hardy, deciduous 

 tree, introduced about twenty years ago from Japan under the name of 

 C. japonica. It has small, smooth, heart-shaped leaves, of a purplish 

 color while young. Propagated by green cuttings, made of the tips of 

 the twigs during the summer, planted in sand in a close frame in a propa- 

 gating house. I have found that the cuttings strike root more readily 

 if slightly dried or wilted before they 

 are placed in the frames. The leaves 

 should be cut away, leaving only two 

 or three of the terminal ones. 



Cercis (Judas Tree, Ptedbud). A 

 genus of three species, one each in 

 America, Europe, China and Japan; 

 the former two small trees growing 

 twenty to thirty feet high, the latter a 

 stocky shrub six to eight feet. Propa- 

 gated by seeds kept in moist sand over 

 winter, and by layers. 



Chamcecyparts (Cypress, White 

 Cedar, Etc.) An extensive genus of 

 coniferous trees, according to the re- 

 cent re-arrangement and classification 

 of the Conifcrce. It is represented in 

 this country by three species : the 

 White Cedar (C. tJiyoides), the Lawson 

 Cypress (C. Lawsoniana), and Nootka 

 Sound Cypress (C. Nulkacnsls) of the 

 Pacific Coast. The Rctinlspora, or 

 Japan Arbor-vitoes, are also included in 

 this genus. Propagated by seed, layers, 

 and cuttings of the smaller twigs and 

 branches taken off in the autumn and planted in frames, or in a cool 

 greenhouse where they will callus slowly ; then given a little higher 

 temperature to force out the roots. Some of them produce roots readily 

 and freely, while others under the same treatment will remain fresh and 

 sound for a year before any roots will be emitted. This difference may 

 often be observed in the varieties of a species, as well as in the different 

 species. With both the varieties of a species, as well as species which 

 are found to be difficult to propagate by cuttings taken from plants in 



Fig. 97.
