richly marked with gold and tinted with bright red; 
C. siberica variegata, a beautiful variety, with silvery 
variegation, and stronger in growth than the other 
forms, with leaves margined with white; and S. siberica 
Gouchaulti, a golden-leaved form strong in growth and 
rich in colour. The dogwoods with coloured foliage 
make neat bushes, two or three feet high. 
CoryLus or Haze,.—There are three varieties of 
the hazel (Corylus avellana) with ornamental leafage, 
and they are all distinct and effective and worthy of 
a place in gardens of quite limited dimensions. They 
attain a height ranging from four to six feet, according 
to the conditions under which they are placed, and with 
space for their development they form handsome bushes. 
They appear to the best advantage when arranged 
in the middle or back row of the shrubbery, and 
the purple-leaved variety is singularly effective when 
associated with the golden elder. 
The varieties are Corylus avellana aurea, a useful form 
with yellowish leaves; C. a. purpurea, a very handsome 
variety with large rich bronze-purple leaves; and C. a. 
Jacinata, an interesting variety with handsomely cut 
leaves. 
ENONYMUS OR SPINDLE TREE.—The European spindle 
tree (Exonymus europeus) has one variety with orna- 
mental foliage that merits a place in the shrubbery. 
This is known as Enonymus europaeus atropurpureus, and 
has bronzy-purple leaves which become purple and 
scarlet in the autumn. It is equally as vigorous as the 
specific form and attains a height ranging from seven to 
ten feet and grows vigorously in all descriptions of soil. 
The most suitable position for this shrub is towards the 
back of the shrubbery. Propagation can be readily 
effected by means of cuttings in the autumn. 
Hiproruz or Sea BuckTHorn.—This distinct shrub 
is more remarkable for the rich effect produced by its
