Benzoin (Styrax Benzoin).—Not to be confounded with Laurus 
Benzoin. It is an aromatic gum resin, not much used except 
in incense. Native of Borneo and Indian islands. It is some¬ 
times called “Gum Benjamin.” False Benzoin is obtained 
from two or three species of the genus Terminalia. 
Bergamot (Monarda didyma). 
Bitter Almond.—Yielded also by Cherry Laurel (Cerasus Lauro- 
Cerasus). 
Bluebell (Scilla nutans). 
Boronia megastigma.—Nearly all the species have aromatic 
leaves, but in the one named the brown and yellow-lined 
flowers are deliciously fragrant. It is a well-known Austra¬ 
lian plant, largely grown now for its perfume both on the 
Continent as well as in English gardens. 
Boswellia serrata (Frankincense or Gum Olibanum).—An Indian 
tree yielding an aromatic gum that is one of the principal 
ingredients in modern as of ancient incense. 
Box Tree (Buxus sempervirens).—A well-known native ever¬ 
green tree which 0. W. Holmes describes as “ breathing 
the fragrance of eternity, for this is one of the odours which 
carry us out of time into the abysses of the unbeginning 
past.” 
Buchu.—The leaves of Barosma crenulata. 
Buxus sempervirens (see Box Tree). 
Cajeput (Melaleuca Cajeputi and M. minor) yields greenish 
aromatic essential oil, employed as an antispasmodic and 
stimulant. The leaves are used in China and Malaysia as a 
tonic in the form of a decoction. 
Californian Bay. 
Calycanthus floridus (Carolinian Allspice).—Young and fresh 
flowers, as also the bark, agreeably scented. 
Camel Grass (Andropogon lanigerum).—Another scented grass 
allied to “ Lemon Grass.” 
Camphor (Kopher, H.).—Dryobalanops Camphora, D. aromatica, 
and probably other species, forming large forest trees in Borneo 
and other Eastern islands, where, as in China, Camphor- 
wood trunks and boxes are valued as resisting the 
termites, or “white ants.” 
Camphor is also obtained from Laurus Camphora, a tree found 
wild in Formosa, and it also exists in the Common Rosemary 
(Rosmarinus officinalis). Antispasmodic.
