YLANG-YLANG. 
As erroneous ideas are current respecting the botanical source of 
Ylang-ylang oil, it is considered necessary to describe at some 
length the tree yielding it, also the trees yielding analogous per- 
fumes. The facts hitherto published in foreign journals regarding 
the physical properties of the oil are also given in extenso, as the 
constitution of the oil indicates the possibility of its synthetic 
formation. 
The tree whose flowers furnish the essential oil known by this 
name—sometimes spelt Ihlang-Ihlang and Alan-guilan (meaning 
“ Flower-of-Flowers ”’)—is the Cananga odorata of Rumphius * 
belonging to the natural order “ Anonacee.” 
Rumphius gives a detailed description + of the Bonga-Cananga, 
as the Malays designate the tree, but his illustration is defective. 
Lamarck gives short notices of this tree { under the headings 
“ Canang Odorant ” and ‘Uvaria odorata.” 
According to Roxburgh, who describes it under the name 
Uvaria odorata §, the plant was brought in 1797 from Sumatra to 
the Botanic Gardens of Calcutta, and he states that in 1809 it had 
a trunk 36 inches in circumference at 4 feet from the ground, and 
was tall in proportion. 
Dunal gives a somewhat more detailed description of (varia
