Properties and Uses.—The plants of this order have fragrant, 
aromatic, tonic, astringent, and febrifugal properties, and many 
of them are valuable timber-trees. 
Cedrela.—The bark of the plants of this genus is generally fragrant.— C. 
Sebrifuga, C. Toona, and other species have febrifugal and astringent barks ; 
they have been used as substitutes for Cinchona.—C. odorata is the source 
of Jamaica or Honduras Cedar.—C. Toona furnishes a wood resembling 
mahogany, which is much used in the East Indies, and is occasionally im- 
ported into this country. It is termed Toon, Tunga, Poma, or Jeea wood ; 
and is said to be one of the woods known as Chittagong w ood.—C. australis 
produces the Red Cedar of Australia. 
Chloroxylon.—The leaves of this genus are dotted, and yield by distilla- 
tion an essential oil.— C. Swietenia is the source of East Indian Satin-wood, 
which is sometimes imported into this country for the use of cabinet- makers. 
It is also employed for making the backs of hair and clothes-brushes, and 
by the turner. 
Oxleya xanthoxyla furnishes the Yellow-wood of Queensland. 
Soymida febrifuga, the Rohuna or Red-wood Tree.—The bark, which 
is Official in the Pharmacopeeia of India, iscommonly known under the name 
of Rohun Bark, and is regarded as tonic, febrifugal, and astringent. In the 
Bengal bazaars, the bark of Strychnos Nuzx-vomica is also known under the 
native name of Rohun, and this has led to its occasional substitution for 
Soymida bark (see Strychnos). It is much employed in the East Indies in 
intermittent fevers, diarrhoea, and dysentery.
