Var. plumosa, Masters. 



Retinispora plumosa, Veitcli ; Chamaecyparis i:)isifcra, var. i)Iumosa, 

 Veitch. 



Usually a dense bush of conical habit with crowded, more or 

 less overlapping branchlet systems ; the leaves awl-shaped, soft 

 and spreading. This juvenile type of the foliage is more or less 

 permanent ; now and then, however, a tree breaks away and 

 produces the adult type of leaves. This variety is very hardy 

 and is one of the commonest conifers in cultivation. It was 

 introduced by John Gould Veitch at the same time as the type. 

 The following colour forms are known : — 



Var, plumosa albo-picta. 



Foliage often white at the tips. 



Var. plumosa argentea. 



Foliage grey or silvery, becoming green in the following spring. 



Var. plumosa aurea. 

 Young branchlets golden yellow, changing to green as the 

 season advances. 



Var. Sanderi, Hort. 



Retinispora Saixderi, Hort. 



A very dwarf plant with juvenile leaves. It is not certain 

 that this variety belongs to C. jnsifera, but it is placed here pro- 

 visionally until it bears fruit. 



Var. squarrosa, Masters. 



Retinispora squarrosa, Siebold and Zuccarini. 



A small tree or dense shrub with handsome glaucous foliage ; 

 the leaves are soft in texture, in alternately opposite pairs, or 

 whorls of four, with the bases clasping the branchlets, narrow, 

 flattened, I in. long, whitened on both surfaces. It was intro- 

 duced in 1843. 



Var. squarrosa sulphurea. 

 Very like the preceding, but the leaves have a yellowish hue. 



From the other species of the ChamcBcyjmris section this 

 cypress is separated by its sharply pointed leaves and prominent 

 white markings below, and by its small cones. 



The Sawara cypress is indigenous in the Central and S. parts 

 of the mainland of Japan at an elevation of 2,000-5,000 ft., and 

 has much the same distribution as C. obtusa. It is a common 

 tree in temple grounds and was introduced into England in 1861. 

 With the exception of the ubiquitous " Lawson cypress," it is
