Melia azedarach, commonly known by many names, including chinaberry tree,<ref name=GRIN>Template:GRIN</ref> Pride of India,<ref>Template:Cite book</ref> bead-tree, Cape lilac,<ref name=GRIN/> syringa berrytree,<ref name=GRIN/> Persian lilac,<ref name=GRIN/> and Indian lilac, is a species of deciduous tree in the mahogany family, Meliaceae, that is native to Indomalaya and Australasia.<ref name=Mabberley1984>Template:Cite journal</ref>
The adult tree has a rounded crown, and commonly measures Template:Convert tall, however in exceptional circumstances M. azedarach can attain a height of Template:Convert.<ref>Floyd, A.G., Rainforest Trees of Mainland South-eastern Australia, Inkata Press 1989, Template:ISBN</ref>
The flowers are small and fragrant, with five pale purple or lilac petals, growing in clusters.
Nomenclature and etymology
The genus name Melia is derived from Template:Wikt-lang (Template:Grc-transl), the Greek word used by Theophrastus (c. 371 – c. 287 BC) for Fraxinus ornus,<ref>Template:Cite book</ref><ref>Template:Cite web</ref> which has similar leaves.<ref>Template:Cite book</ref> The species azedarach is from the French 'azédarac' which in turn is from the Persian 'āzād dirakht' (ازادرخت ) meaning 'free- or noble tree'.<ref>Merriam-Webster</ref>Template:Full citation needed
Melia azedarach should not be confused with the Azadirachta trees, which are in the same family, but a different genus.
Common names of Melia azedarach include chinaberry, chinaberry tree, Persian lilac (ambiguous), this name is also used for a lilac hybrid, Syringa × persica. other names include Texas umbrella, umbrella tree, umbrella cedar, white cedar, bead-tree, Cape lilac, Ceylon cedar, Ceylon mahogany, syringa, syringa berry tree.<ref name=multi>Template:Cite web</ref>
Names in other languages include Kavadya Nimb or Bakan (Marathi) malai vembu (Template:Lang-ta), bakain (Hindi), seringboom (Afrikaans), zanzalakht (Template:Lang-ar), dharek or dhraik (Template:Lang-ur), and turaka vepa (Telugu).<ref name=multi/> Ghora ("horse") neem (Template:Lang-bn), hebbevu in Kannada, Tora Shandai in Pashto, vilayati ("foreign") neem in Bundelkhand, and bkain in Haryana, Rajasthan, East Uttar Pradesh and Jharkhand, India. It has been naturalized in Madagascar, where it is called voandelaka, and in Israel, where it is called izdarekhet (אזדרכת) Derived from the above Persian name)
Uses and ecology
The main utility of chinaberry is its timber. This is of medium density, and ranges in colour from light brown to dark red. In appearance it is readily confused with the unrelated Burmese teak (Tectona grandis). Melia azedarach – in keeping with other members of the family Meliaceae – has a timber of high quality, but as opposed to many almost-extinct species of mahogany, it is under-utilised. Seasoning is relatively simple, in that planks dry without cracking or warping and are resistant to fungal infection. The taste of the leaves is not as bitter as neem (Azadirachta indica).
The cut branches with mature fruit are sold commercially to the florist and landscaping trade particularly as a component for outdoor holiday décor. The fruits may persist for some time prior to shattering off the stem or discoloring, which occurs rapidly after a relatively short time in subfreezing weather.
Some hummingbirds like the sapphire-spangled emerald (Amazilia lactea), glittering-bellied emerald (Chlorostilbon lucidus) and planalto hermit (Phaethornis pretrei) have been recorded as feeding on and pollinating the flowers; these only take it opportunistically.<ref>Baza Mendonça & dos Anjos (2005)</ref>
In Kenya the trees have been grown by farmers and used as fodder trees. The leaves can be fed to cattle to improve milk yields and improve farm incomes.<ref>http://r4d.dfid.gov.uk/PDF/Outputs/Forestry/DFID_impact_case_study_Fodder_trees_FINAL%5B1%5D.pdf</ref>
In discussions on the toxicity of fruits of this species, it is important to clearly differentiate between the non-toxic ripe flesh of the fruit and the toxic seed which is enclosed in a hard, fluted endocarp. Fruits have evolved to be eaten by animals which eat the flesh surrounding the hard endocarp or ingest the entire fruit and later vent the endocarp. If the endocarp is crushed or damaged during ingestion or digestion, the animal will be exposed to the toxins within the seed. The processes of mastication and digestion, and the degree of immunity to the particular toxins, vary widely between species, and there will accordingly be a great variation in the clinical symptoms following ingestion.<ref>'Medicinal and Poisonous Plants of Southern and Eastern Africa' - John Mitchell Watt & Maria Gerdina Breyer-Brandwijk (E&S Livingstone, 1962)</ref>
Fruits are poisonous to humans if eaten in quantity.<ref>Russell et al. (1997)</ref> However, like those of the yew tree, these toxins are not harmful to birds, who gorge themselves on the fruit, eventually reaching a "drunken" state. The birds that are able to eat the fruit spread the seeds in their droppings. The toxins are neurotoxins and unidentified resins, found mainly in the fruits. 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 arrest, rigidity, lack of coordination and general weakness. Death may take place after about 24 hours. Like in relatives, tetranortriterpenoids constitute an important toxic principle. These are chemically related to azadirachtin, the primary insecticidal compound in the commercially important neem oil. These compounds are probably related to the wood and seed's resistance to pest infestation, and maybe to the unattractiveness of the flowers to animals.Template:Citation needed
Leaves have been used as a natural insecticide to keep with stored food, but must not be eaten as they are highly poisonous. Chinaberry fruit was used to prevent insect larvae from growing in the fruit. By placing the berries in drying apples (etc.) and keeping the fruit turned in the sun without damaging any of the chinaberry skin, the fruit will dry and not have insect larvae in the dried apples.Template:Citation needed
As invasive species
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 by some groups as far north as Virginia and Oklahoma.<ref>Langeland & Burks</ref> 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 the United States is diminished by its tendency to sprout where unwanted and to turn sidewalks into dangerously slippery surfaces when the fruits fall, though this is not a problem where songbird populations are in good shape. As noted above, the possibility of commercially profitable harvesting of feral stands remains largely unexplored.
