and short, flat branchlets. The leaves are arranged in opposite 

 pairs, and are of a greenish-yellow hue. C. Fortuhei is one of the 

 most handsome members of the genus, with spreading branches 

 plentifully supplied with narrow leaves, rich green above and 

 soft green below. C. pedunculata (Taxus Harringtoniana) is a 

 distinct Japanese shrub, with horizontal branches and deep. green 

 leaves; it grows about 8ft. high, and is of bushy, pyramidal 

 habit. C. p. fastigiata (Podocarpus koraianus) (Fig. 311), also 

 from Japan, in habit bears some resemblance to the , Irish 

 Yew. It is of slow growth, quite hardy, and well adapted 

 for winter bedding and window boxes. Its narrow leaves, about 

 2in. long, spirally arranged around the erect shoots, are deep 

 green above and paler below. 



Cryptomeria- — Only one species is found in this genus, and 

 that is thoroughly hardy in the British Isles. It enjoys a rich, deep 

 soil, thoroughly well drained and beyond the influence of cold east 

 winds. C. japonica (Japan Cedar) (Fig. 312) is a charming tree, 

 and useful also for avenues. Of free growth, with a straight 

 trunk covered with rough brown bark, it forms a much-branched 

 tree of pyramidal habit. The spreading branches are inclined 

 to droop, and are very effective when carrying the spikes of male 

 catkins. C. j. elegans is an elegant tree, less vigorous than the 

 type, with a straight, upright trunk, and horizontal branches 

 clothed with narrow, sharply-pointed leaves, tender green in spring, 

 but which in autumn assume a brownish-crimson hue, giving 

 it a distinct and pleasing appearance. A beautiful tree for the 

 lawn as well as for winter bedding, and in a young state is useful 

 for window boxes. C. j. e. nana forms a bushy shrub in the rock 

 garden. Like the last-named the foliage becomes stained with 

 rich crimson, which shade it retains until spring. C. j. Lobbii 

 differs from the type by reason of its more compact, sturdy habit, 

 and smaller and deeper green leaves, as well as being of more rapid 

 growth. C. j. L. nana is a much-branched spreading bush, 

 growing only a few feet high. C. j. spiralis is useful for the 

 rockery, but is more curious than beautiful. 



Cunninghamia. — Unfortunately C. sinensis is hardy only in 

 sheltered parts of the British Isles. Suitably placed it makes a 

 handsome specimen, but in localities where severe frosts are 

 prevalent the foliage becomes discoloured, and is then any- 

 thing but decorative. It prefers a light, well-drained soil, and 

 on no account should it be exposed to east winds. Propagation 

 is best effected by seeds, as plants raised from cuttings do not 

 as a rule give satisfaction. 



Cupressus. — This very ornamental group now comprises the • 

 Retinosporas of gardens. Their habit is equally varied, some 

 being columnar, or fastigiate, others spreading and pendulous, and 

 a few quite globose. The following list, although not complete,
