Varieties. ‘ 
« D.C. 2 foliis variegatis, — The leaves have 
a narrow portion of yellow at the edges, = 
« D.C. 3 flore dlbo. — Flowers white. 
The prettiest species of the genus, more especially 
when grafted 1 or 14 foot high on D. Lauréola. It is 
also valuable for rockwork, and growing in pots, 
on account of its dwarf habit, and the beauty and 
delightful fragrance of its flowers. For ordinary 
purposes it is propagated by layers, and it thrives j 
best in peat soil kept rather moist. 1552. D, Cnedram

Virginia. Height 3 ft. to 4 ft. Introduced in 
1750, and common in collections of peat-earth 
shrubs. Flowers yellow ; March. 
The whole plant has a yellow aspect, and the 
flowers are of a brighter yellow than the leaves, 
without the admixture or contrast of any other 
colour; thus producing a monotonous ap- 
pearance rare among plants. The flowers are 
produced while the plant is leafless, and, in 
England, they are seldom, if ever, followed by 
seeds. The bud of the shoot of the same year 
is enclosed in the bud of the inflorescence. The 
young plants are very liable to be eaten by snails 
Propagated by layers, which require two yearn to 
root properly, or by American seeds.
