Ailanthus triphysa (also Ailanthus malabarica) is a medium to tall evergreen rainforest tree in Asia and Australia. The wood may be used for matchwood and plywood. The tree is known as halmaddi in India, where its resin, also called halmaddi, may be used in incense. Inappropriate extraction methods were resulting in trees dying, so by the 1990s the Indian forestry department had banned extraction.
It occurs in India, including the Andaman Islands; Sri Lanka; Myanmar; South-Central and Southeast China; Thailand; Laos; Malaysia, including Peninsular Malaysia, Sarawak and Sabah; Cambodia; Vietnam; Philippines; Jawa, Kalimantan, Sulawesi and Maluku in Indonesia; and Australia. [1] In Australia, Ailanthus triphysa occurs as two isolated populations in Western Australia (at Prince Regent River and on the offshore Coronation Island, in the Kimberley), and from Cape York in Queensland and as far south as the Susan Island Nature Reserve at Clarence River (New South Wales). [2] [3]
Ailanthus triphysa is a medium to tall evergreen tree to 30 m and diameter of 1.2 m. [4] The trunk is not buttressed, but rather straight and cylindrical. The bark is grey, somewhat rough and resembling sandpaper to the touch. The leaves are pinnate, curved and sickle shaped drawn out to a point and are particularly oblique at the base. Venation is prominent, the net veins more obvious under the leaf. Flowers are creamy green, flowering in November to January in Australia. The fruit is a samara, often forming in threes.
Stem: Bark greyish, lenticellate; blaze yellow with red speckles.
The leaves bear twigs 1 cm or more in diameter, and the stipules very small. Leaflet blades are falcate, about 5-12 x 0.9–2 cm, very unequal-sided particularly at the base. Lateral veins forming loops well inside the blade margin. Midrib raised in a depression on the upper surface of the leaflet blade. Numerous, closely spaced oil dots are visible with a lens.
The flowers polygamous, and are greenish yellow in color. Inflorescence axillary, branched panicle, about 10–20 cm long. The sepals are about 0.5-0.8 mm long. Petals are about 3.5-4.5 x 2 mm in dimensions, stamens are about 3–4 mm long in male flowers, and carpels are 2-4 mm usually 3mm long. Ovules are 1 per carpel Flowering season in India are from the month of December to May. Fruit: Fruits green to greenish brown, papery in texture. Samaras about 5-6 x 1–2 cm. Main vascular bundle to the seed connected to an intramarginal vein on the samara.
On the island of Yamdena, eastern Indonesia, the tree occurs in dense dry deciduous forest, growing in the understory, taller than 4m with a dbh less than 30cm. The canopy of these forests is dominated by Ebenaceae (particularly Diospyros) and Fabaceae. [6] On Coronation Island, off the coast of the Kimberley, Western Australia, the tree grows in vine thickets (monsoon rainforest pockets). Because of the limited and isolated nature of the Western Australian populations, they have conservation significance. [2]
The wood is yellowish and brittle; as well as making excellent charcoal, [7] the timber may be used for matchwood and plywood. [8] When the bark is cut, a sticky resin is exuded, which becomes brittle on drying; this resin may be used for medicinal purposes, and particularly, because of its aromatic nature, it may be burned as incense, either directly, or as an ingredient in incense sticks. [9] In India, the incense resin is named halmaddi, after the local name for the tree itself. [8] Due to crude extraction methods which resulted in trees dying, by the 1990s the Forest Department in India had banned resin extraction; this forced up the price of halmaddi, and its use in incense-making declined. [10] [11] In Cambodia, the resin is also used as incense, whereas the bark is used in local folk medicine against dysentery and intestinal œdema. [7]
The wood contains various alkaloids and quassinoids, including beta-carboline, [12] and has been used for the treatment of dyspepsia, bronchitis, ophthalmia and snake bite. [13]
As well as its botanical names, this tree has common, or vernacular, names. These include: halmaddi, but, [14] in India; hoëm thôm (Khmer, ="severe œdema"); [7] thanh thât (Vietnam); [14] white bean, ferntop ash (Australia).

Sandalwood is a class of woods from trees in the genus Santalum. The woods are heavy, yellow, and fine-grained, and, unlike many other aromatic woods, they retain their fragrance for decades. Sandalwood oil is extracted from the woods. Sandalwood is often cited as one of the most expensive woods in the world. Both the wood and the oil produce a distinctive fragrance that has been highly valued for centuries. Consequently, some species of these slow-growing trees have suffered over-harvesting in the past.
Plumeria, also known as frangipani, is a genus of flowering plants in the subfamily Rauvolfioideae, of the family Apocynaceae. Most species are deciduous shrubs or small trees.

India is the world's main incense producing country, and is also a major exporter to other countries. In India, incense sticks are called Agarbatti (Agar: from Dravidian probably Tamil அகில், அகிர், Sanskrit varti, meaning "stick". An older term "Dhūpavarti" is more commonly used in ancient and medieval texts which encompasses various types of stick incense recipes. Incense is part of the cottage industry in India and important part of many religions in the region since ancient times. The method of incense making with a bamboo stick as a core originated in India at the end of the 19th century, largely replacing the rolled, extruded or shaped method which is still used in India for dhoop.
