64 BOOK OF THE SCENTED GARDEN 
Iang-Ilang (see Ylang- Ylang) (Flower of Flowers). 
Tris florentina (Orris-root).—The dried rhizomes of this 
and other species of German or Flag Iris are agree- 
ably scented like violets, and form the basis of violet 
powders and other dry perfumes for pomanders, bags, 
or sachets, etc. Orris-root is largely cultivated, 
dried in the sun, and prepared in S. France and Italy.

Juniper (Juniperus). 
Lastrea montana, L. emula, and other species are scented. 
Lathyrus odoratus (Sweet Peas).—Well-known and 
exquisite annuals. 
Laurelia aromatica (Sweet Laurelia).—A rare evergreen 
with fleshy and deliciously fragrant foliage, hardy 
only in very warm and sheltered localities. It grows 
20 feet high in Co. Wicklow. 
Laurus nobilis (Sweet Bay).—Foliage aromatic and much 
used for flavouring confectionery, figs, sardines, etc. 
Laurus sassafras is N. American ‘Spice Bush,” 
having perfumed leaves and aromatic bark. The 
‘‘Cherry Laurel” is Cerasus Jlauro-cerasus, and its
