T. occidentalis Booth's Dwarf. Here we see a variety of these 

 forms already referred to that are very similar to one another. 



The next larger and broader tree in the middle after the last 

 American Arbor-Vitae is a Variegated American Arbor- Vitae. 

 Another specimen of it is directly ahead, also in the middle, and a 

 third stands to the left by the outer road, and between these two. 



The next two larger and broader specimens, one in the middle 

 and the other by the outer road, are the American Arbor-Vitae. 

 Now we come to a group of eight yellow- foliaged evergreens. 

 They are Golden Peabody Arbor-Vitae (p. 129). The next two 

 darker-colored trees, one in the middle and the other with an open 

 center by the other road, are the Spiral Arbor-Vitae. Next in the 

 center the slender-foliaged and thready looking tree is 



Thuja occidentalis var. nliformis, Threadtwig Arbor-Vitae 



This odd form has very slender branches. 



The next ten trees are the Japanese Arbor-Vitae (p. 125). 



Beyond them stands a large American elm and on the other 

 side of it are the last specimens of Arbor-Vitae. The first one on 

 the left near the outer road is a Spiral Arbor-Vitae (p. 129). The 

 first in the middle is a Siberian Arbor-Vitae (p. 128). Of the next 

 two, nearer the outer road, the outer one is a George Peabody 

 Arbor-Vitae, and the inner is a common Arbor-Vitae. There 

 remain now six small trees. The three nearest the cross walk are 

 the American Globe Arbor-Vitae and the other two low bushy 

 ones are Siberian Arbor-Vitae. The remaining small slender one 

 by the outer road is the common American Arbor-Vitae. 



General Discussion 



The species of Thuja are all evergreen cone-bearing trees. 

 There are six different known kinds. Two are not represented in 

 the Garden, viz. : the Korean Arbor-Vitae, T. koraiensis, found in 

 Korea, and T. setchuensis of western China. The last is not in 

 cultivation. The foliage of these trees resembles that of the 

 cypress, Chamaecyparis, in the flat, scaly divided branchlets and 

 the leaf arrangement. There is apt to be confusion at times in 

 this respect. But the cones are markedly different, though not
