IV. FLOWERS. 
In quite a number of plants, particularly the Labiatae 
and Composite, principles having medicinal and other 
properties occur in relatively large amount in the 
flowers. These principles are, as a rule, more or less 
volatile and aromatic, many of them being used in 
perfumery and for flavoring, as well as for medicinal 
purposes.

enous to the Molucca Islands, where it is also cultivated, 
as well as in Zanzibar, Ceylon and Java. The flower- 
buds are collected, dried in the sun or artificially, the 
color changing from a crimson to a brownish. The 
chief commercial supplies come from Amboyna, Penang 
and Zanzibar, the former two varieties being preferred.
