46 HARDY COKlIfEROUS TREES. 



mental plant than the parent, with thickly-set branches, the 

 greater portion of which is of a desirable golden-yellow colour. 

 It is one of the best of the small growing ornamental conifers. 



C. pisifera squarrosa- This is of bush-like growth, 

 thickly arranged both in branches and branchlets, and with 

 needle-shaped, silvery-white foliage. 



C. pisifera squarrosa dubia is a compact, little 

 bush, but varies a good deal both in shape and density of 

 branches. The colour of foliage nearly approaches the latter, 

 but individually the leaves are stouter and longer. The cones 

 of all these varieties are identical with those of C. pisifera. 



C- sempervirens, Linnaeus. {Sy7tonyms:C. fasti- 

 giata, D. C. ; C. pyramidalis, C, Whitleyana^ Carriere.) Levant, 

 Himalaya. This is of distinctly pyramidal growth, the 

 branches usually heavy, and thickly beset with tiny branch- 

 lets, covered with smooth, imbricated, yellowish-green leaves. 

 The cones are plentifully produced, and being of a light 

 brown colour, contrast strangely with the heavy masses of 

 foliage. Each cone is fully i inch in diameter, nearly round, 

 and composed of convex angular scales, with a raised point 

 in the centre of each. There is a noble clump of these trees 

 at Penrhyn Castle, North Wales. 



C. sempervirens horizontaiis differs only from 

 the species in the spreading branches and smaller cones, but 

 it is by no means common in cultivation. 



C. thurifera, Humboldt Mexico. This bears a great 

 resemblance to the better known Thuya orientalis, but the 

 branches are usually more pendent, and altogether it is a 

 more desirable specimen for ornamental purposes. It re- 

 quires a warm situation and rich soil ; indeed, the largest 

 specimen I have seen is growing on an estate in Ireland. 

 Wherever it will grow this species is well worthy of culture, 

 but it is not generally hardy. The specimens I have seen 

 under the name of C. thurifera are quite distinct from any 

 other species of my acquaintance. 



C- Thyoides, Linnaeus. {Synonyms : Chamcecyparis 

 sp/ucroidea, Spach ; Retinispora ericoides^ Gordon.) Eastern
