CUPRESSUS CYDONIA 451 



C. THYOIDES, Linnceus. WHITE CEDAR. 



(Chamaecyparis sphaeroidea, Spach.~) 



"*f 



A tree usually 20 to 50, but up to 70 or 80 ft. high in a wild state, with a 

 reddish brown trunk 2 ft. or more in diameter ; of slender columnar form in 

 a young state, and shortly branched. The smaller ramifications are flat, two- 

 ranked, and somewhat fan-shaped ; the branching as a whole is bushy, spiral, 

 and irregular. The trees shed their effete branchlets in fan-shaped pieces, 

 i to 3 ins. long. Leaves in four ranks, the lateral ones usually longer than 

 those above and beneath, which are marked with a conspicuous raised gland ; 

 they are ^ to ^ in. long, pointed, the lateral ones spreading at the tips ; dull 

 grey-green. Cones to in. in diameter, globose, very glaucous ; scales six, 

 each with a triangular boss in the centre. 



Native of Eastern N. America, usually found in cold, swampy, often 

 inundated ground ; introduced in the eighteenth century. This tree was more 

 frequently cultivated in earlier times, before the Californian and Japanese 

 cypresses were introduced, than it is now. It is not so striking as they are, 

 but is worth growing for its ne*at columnar habit. Although a swamp tree 

 in its native country it will thrive better here in ordinary, deep, moist soil. 

 In New Jersey immense quantities of trunks of this tree have been found 

 immersed in swamps, many of them, although buried for hundreds of years, 

 perfectly sound and not at all water-logged. It is very distinct in its branch- 

 ing from any other of Chamaecyparis group. 



Var. GLAUCA (syn. kewensis). Leaves glaucous, especially beneath. 



Var. LEPTOCLADA (Retinispora leptoclada, Gordon) A very distinct form 

 of dwarf, close, pyramidal habit ; the main branches erect, the smaller ones 

 very short. Besides the ordinary type of adult foliage it has branches with 

 the juvenile type of leaf, longer and more awl-shaped. It appears to have 

 been raised in a nursery at Andelys, in N.W. France, about 1850. 



Var. VARIEGATA. Young branchlets yellow. 



C. TORULOSA, Don. HIMALAYAN CYPRESS. 



A tree up to 150 ft. high in the Himalaya, with horizontal branches, and 

 bark peeling off in long strips. Branchlets arranged in opposite ranks, more 

 or less drooping, the final subdivisions equally four-sided, about ^ m - m 

 diameter. Leaves of equal size, deep green, scale-like ; overlapping at the 

 base, the terminal part ovate, bluntish, incurved and thickened at the point, 

 often grooved on the back. Cones purplish when young, globose, very shortly 

 stalked, \ to f in. in diameter ; scales eight, rarely ten each, with a small 

 central boss. 



Discovered by Buchanan-Hamilton during his famous journey in Nepal, 

 1802-3; introduced in 1824. It is tender, and only seen to advantage in the 

 southern and western counties. I have specimens from Hewell Grange, 

 Worcester ; Ravenhill, Sevenoaks ; and Penrhyn, Wales. 



Var. CORNEYANA, Carrtere, has the branchlets arranged irregularly rather 

 than in two opposite ranks, and they are more pendulous. 



CYDONIA. QUINCE. ROSACES 



A group of five species of trees and shrubs closely allied to Pyrus, 

 but differing in the many-seeded cells of the fruit. Leaves alternate, 

 deciduous, simple, with large stipules. Flowers normally in almost 

 stalkless clusters, or solitary. Petals five; stamens numerous; calyx
