Euphorbracee—Buxus. 401 
3. BUXUS. 
Evergreen shrubs or small trees with alternate exstipulate 
leaves and axillary bracteolate clusters of polygamous flowers. 
Perianth of 4 segments in the male, and 4 to 12 segments in 
the female flowers. Stamens 4. Cells of the capsule l- or 
2-seeded. Besides the hardy species, there are several others 
in Africa and the West Indies. The name is derived from the 
Greek appellation zvé£os. 
1. B. sempervirens. Common Box.—This handsome shrub 
is indigenous in Surrey, covering a large area on Box Hill. 
The varieties in cultivation are numerous, both variegated 
and green. There is the dwarf bushy form used for edging, 
and several varieties with gold and silver striped foliage. 
B. s. myrtifolia is a robust form with relatively large coria- 
ceous foliage; and B. s. rosmarinifolia is a dwarf bush with 
slender branches and narrow leaves. The names of the 
varieties, arboréscens, angustifolia, rotundifolia, etc., suggest 
their characteristic features. 
2. B. Baledrica.--This is a more robust-growing species 
with yellowish green oblong-elliptical emarginate coriaceous 
leaves about 2 inches long with a cartilaginous margin. The 
female flowers only are sessile in this species, whilst in B. sem- 
pervirens those of both sexes are sessile. This handsome ever- 
green shrub is a native of Minorca. 
B. Japéniea is a variable species closely allied to the com- 
mon European B. sempervirens, differing in the large dilated 
furrowed rudimentary ovary of the male flowers.

with large convolute stipules. Flowers unisexual, incon- 
spicuous, usually arranged in dense spikes, heads, or catkins.
