Thread -branched Japan Cypress (Retinospora filijera Fowlei ) is a unique form 

 having" peculiar, thread-like or whip-like branches, and seems to be one of the 

 most vigorously constituted of the entire group. In time it becomes a bushy 

 shrub or small tree from which stiffness and formality are wholly lacking-. 

 It should be used, even in very small collections, on account of its hardiness and 

 vigorous habit of growth. 



Golden Thread-branched Japan Cypress. Retinospora filif era aurea. In this 

 we have the showy golden form'of thread-branched Japan cypress. Its foliage 

 is abundantly marked with yellow in a glowing tint, which is well retained 

 through summer, even when the tree is grown in partial shade; a peculiar, dis- 

 tinct and valuable variety. 



Obtuse-leaved Japan Cypress. Cupressus obtusa Sieb. and Zucc. By some this 

 is regarded as the finest of all the Japan cypresses. In Japan, where it be- 

 comes a tree sixty feet tall, it is considered sacred and its wood is used in the 

 construction of temples. The foliage is a clear, brilliant green in color and for 

 ornamental purposes the value of the tree can scarcely be rated too high. As 

 the tree acquires size it is apt to become open and thin, which can be obviated 

 by annual shearing or pruning in its younger years to increase the number of 

 branches. 



FIG. XVII Graceful Obtuse-leaved Japan Cypress. Cupressus obtusa gractlts. 

 Compact obtuse-leaved Japan Cypress ( Cupressus obtusa compacta] is a neat, 

 dwarf, compact grower, which has foliage similar to the obtuse-leaved Japan 

 cypress and is one of the very best of the small, low-growing evergreens.
