longer than that of any other species, and for this quality 

 principally, as well as for its extreme lightness, it is prefer- 

 red at Baltimore and Philadelphia for shingles, which are 

 cut transversely to the concentric circles, and not parallel 

 like those of the Cypress." 



Var, Tariegata, London. This is a distinctly marked 

 plant that we have grown for several years with much 

 satisfaction. It is entirely hardy, and forms a striking 

 contrast in a collection. A portion of the branchlets and 

 leaves are marked with white and yellow dots and stripes. 



Var. liana, London. A glaucous and very compact 

 dwarf variety, which is perhaps unknown in this country. 



Var. Kewensis, Hort. Syn. ChamaBcyparis sph&roidea 

 glauca, Endlicher. A variety that is said to be very dif- 

 ferent from the species in many characteristics. The 

 foliage is of a peculiar silvery glaucousness, and the form 

 of the tree is more compact. It grows about the same 

 height as the species. 



Var, atrovirens, Lawson. This differs from the species 

 only in having the leaves almost entirely free from the 

 glaucousness of the parent, and of a bright shining green 

 color. 



4. C. fragrans, Kellogg. FRAGRANT CYPRESS. 

 Is described in the Proc. of the Cal. Acad. of Nat. Sci- 

 ence, Vol. I, page 103, as follows: "This species bears 

 the nearest resemblance to Cupressus Lawsoniana, but 

 differs from it most strikingly in the brighter green of its 

 foliage, and its far denser branchlets ; also in the leaves 

 being narrower, much more angular, and sharper pointed ; 

 the cones are from one-third to twice the size, more rough ; 

 also in color, form, and more sparse distribution, etc. ; it 

 is also a tree of larger proportions in all respects." 



The wood abounds in an oil, which exhales a peculiar 

 spicy aroma ; hence it is frequently known among lumber-
