Commonly called 'Persian Lilac', 'White Cedar', 'Cape Lilac', 'Chinaberry' or 'Bead Tree', ''Melia azedarach''(
syn. ''M. australis, M. japonica, M. sempervivens''), is a
deciduous tree in the mahogany family
Meliaceae, native to
India, southern
China and
Australia. In
South Africa it is commonly but erroneously called Syringa, which is in fact the lilac genus. The genus ''Melia'' includes four other species, occurring from southeast
Asia to northern
Australia. They are all deciduous or semi-
evergreen small trees.
The adult tree has a rounded to upright top, and measures between 7 and 12
metres in height. The
flowers are small and fragrant, with five pale purple or lilac petals, growing in clusters. The
fruit is a
drupe, marble-sized, light yellow at maturity, hanging on the tree all winter, and gradually becoming almost white.
Timber is of medium density, and ranges in colour from light brown to dark red. In appearance it is readily confused with the unrelated ''
Tectona grandis'' (Burmese Teak). ''Melia azedarach'' in keeping with other members of the family ''
Meliaceae'' has a timber of high quality, but is under-utilised. Seasoning is relatively simple in that planks dry without cracking or warping and are resistant to fungal infection.
The
leaves are up to 50 cm long, alternate, long-petioled, 2 or 3 times compound (odd-pinnate); the
leaflets are dark green above and lighter green below, with serrate margins. They have been used as a natural
insecticide to keep with stored
food, but must not be eaten as they are highly
poisonous. A diluted
infusion of leaves and trees has been used in the past to induce
uterus relaxation.
The flowers are unattractive to
bees and
butterflies. The hard, spherical seeds were widely used for making
rosaries and other products requiring
beads, before their replacement by modern
plastics.
All parts of the
plant are poisonous to
humans if eaten. The toxic principles are tetranortriterpene neurotoxins and unidentified resins; it is found most concentrated in the fruits. Some
birds are able to eat the fruit, spreading the
seeds in their droppings, but 15
grams are a lethal dose for a 22-
kilogram pig. The first symptoms of poisoning appear a few hours after ingestion. They may include loss of appetite, vomiting, constipation or diarrhea, bloody faeces, stomach pain, pulmonary congestion, cardiac paralisis, rigidity, lack of coordination and general weakness. Death may take place after about 24 hours.
The plant was introduced around
1830 as an ornamental in the
United States (
South Carolina and
Georgia) and widely planted in southern states. Today it is considered an
invasive species as far north as
Virginia and
Oklahoma.
[1] But
nurseries continue to sell the trees, and seeds are also widely available. It has become naturalized to tropical and warm temperate regions of
the Americas and is planted in similar climates around the world. Besides the problem of toxicity, its usefulness as a shade tree in urban areas is diminished by its tendency to sprout where unwanted and to turn sidewalks into dangerously slippery surfaces when the fruits fall.
Uses
Cape Lilac is used in musical instrument making, as a top for the acoustic
Stompbox and guitar inlays by Western Australian luthier
Ellis Guitars.
