root easily from cuttings, or can be layered with 

 success. The variegated forms are best grafted on 

 stocks of the species they belong to, and /. Sabina 

 (the Savin) and its varieties are easily raised from 

 cuttings or layers, the latter being a very easy way 

 of propagating them. 



CUPRESSUS. — This genus is divided into two 

 sections, viz., the true Cypresses, represented by 

 C. macrocarpa, C. sempervirens, &c., and Chamaecy- 

 paris, of which Cupressus lawsoniana is the best 

 known species. With the former section seeds 

 are the best means of reproducing the species, 

 while the few varieties should be grafted on stocks 

 of the parent species. The handsome C. macrocarpa 

 var. lutea especially should be worked on the type, as 

 it is practically a failure from cuttings, and if grafted 

 on C. lawsoniana, as is sometimes done, it makes a 

 short, stumpy bush instead of a typically tall colum- 

 nar tree. In the Chamaecyparis section Cupressus 

 lawsoniana, C. nootkate.nsis, C. obtusa, C. pisifera, and 

 C. thyoides are the only species, though there are 

 a host of varieties attached to them, the forms of 

 the three latter species, in fact, including all the 

 various plants more commonly known under the 

 generic title of Retinospora. The species should 

 be raised from seed, which is easily obtainable and 

 germinates readily, or in default they will root from 

 cuttings. The varieties, with a few exceptions, are 

 quickly propagated by cuttings, those that require 

 to be grafted being C. lawsoniana var. lutea, the 

 variegated forms of C. nootkaiensis, and C. obtt4sa
