OSMANTHUS. 0. rotwndifolius is a dwarf variety 
of O. Aquifolium, with very coriaceous, obovate, slightly 
lobed leaves. The varions forms of Osmanthus, especially 
the green- and purple-leaved varieties, are serviceable for 
town gardens, also for growing in pots or tubs for 
the decoration of vestibules, balconies, &c. The variety 
named atropurpurea makes a splendid subject for 
winter bedding, especially when in association with the 
Golden-leaved Yew, the leaf-colonr standing out in bold 
yet good contrast. They delight in good loamy soil and 
an open sitnation, yet one shielded from biting winds. 
Copious supplies of water should be given, particularly 
in the early part of the growing scason. Propagation
