Lawsonia inermis, also known as hina, the henna tree, the mignonette tree, and the Egyptian privet, [4] is a flowering plant and one of the only two species of the genus Lawsonia, with the other being Lawsonia odorata . The species is named after the Scottish physician Isaac Lawson, a good friend of Linnaeus.
Henna is a tall shrub or small tree, standing 1.8 to 7.6 m tall (6 to 25 ft). It is glabrous and multi-branched, with spine-tipped branchlets. The leaves grow opposite each other on the stem. They are glabrous, sub-sessile, elliptical, and lanceolate (long and wider in the middle; average dimensions are 1.5–5.0 cm x 0.5–2 cm or .6–2 in x 0.2–0.8 in), acuminate (tapering to a long point), and have depressed veins on the dorsal surface. Henna flowers have four sepals and a 2 mm (0.079 in) calyx tube, with 3 mm (0.12 in) spread lobes. Its petals are ovate, with white or red stamens found in pairs on the rim of the calyx tube. The ovary is four-celled, 5 mm (0.20 in) long, and erect. Henna fruits are small, brownish capsules, 4–8 mm (0.16–0.31 in) in diameter, with 32–49 seeds per fruit, and open irregularly into four splits. [5]
The henna plant is native to northern Africa, Asia and northern Australia, in semi-arid zones and tropical areas. [6]
It produces the most dye when grown in temperatures between 35 and 45 °C (95 and 113 °F). [7] During the onset of precipitation intervals, the plant grows rapidly, putting out new shoots. Growth subsequently slows. The leaves gradually yellow and fall during prolonged dry or cool intervals. It does not thrive where minimum temperatures are below 11 °C (52 °F). Temperatures below 5 °C (41 °F) will kill the henna plant.
Its dried leaves are the source of the dye henna used to dye skin, hair and fingernails, as well as fabrics including silk, wool and leather.
Azadirachta indica, commonly known as neem, margosa, nimtree or Indian lilac, is a tree in the mahogany family Meliaceae. It is one of the two species in the genus Azadirachta. It is native to the Indian subcontinent and to parts of Southeast Asia, but is naturalized and grown around the world in tropical and subtropical areas. Its fruits and seeds are the source of neem oil. Nim is a Hindustani noun derived from Sanskrit nimba (निंब).
Melicoccus bijugatus is a fruit-bearing tree in the soapberry family Sapindaceae, native or naturalized across the New World tropics including South and Central America, and parts of the Caribbean. Its stone-bearing fruits, commonly called quenepa or guinep, are edible. Other names for the fruits include limoncillo, Bajan ackee, chenet, Spanish lime and mamoncillo.
Lythraceae is a family of flowering plants, including 32 genera, with about 620 species of herbs, shrubs, and trees. The larger genera include Cuphea, Lagerstroemia (56), Nesaea (50), Rotala (45), and Lythrum (35). It also includes the members of the former families of the pomegranate and of the water caltrop. Lythraceae has a worldwide distribution, with most species in the tropics, but ranging into temperate climate regions as well.
Mehndi is a form of temporary skin decoration using a paste created with henna. In the West, mehndi is commonly known as henna tattoo, although it is not a permanent tattoo.
Lawsone (2-hydroxy-1,4-naphthoquinone), also known as hennotannic acid, is a red-orange dye present in the leaves of the henna plant, for which it is named, as well as in the common walnut and water hyacinth. Humans have used henna extracts containing lawsone as hair and skin dyes for more than 5,000 years. Lawsone reacts chemically with the protein keratin in skin and hair via a Michael addition reaction, resulting in a strong permanent stain that lasts until the skin or hair is shed. Darker colored staining is due to more lawsone–keratin interactions occurring, which evidently break down as the concentration of lawsone decreases and the tattoo fades. Lawsone strongly absorbs UV light, and aqueous extracts can be effective sunless tanning agents and sunscreens. Lawsone is a 1,4-naphthoquinone derivative, an analog of hydroxyquinone containing one additional ring.
Bombax buonopozense, commonly known as the Gold Coast bombax or red-flowered silk cotton tree, is a tree in the mallow family. It is also known in the Dagbani language as Vabga.
Gluta travancorica is a species of plant in the family Anacardiaceae. It is endemic to the southern Western Ghats in India.
Vatica chinensis is a species of flowering tree in the family Dipterocarpaceae, found in South Asia.
Crataegus crus-galli is a species of hawthorn known by the common names cockspur hawthorn and cockspur thorn. It is native to eastern North America from Ontario to Texas to Florida, and it is widely used in horticulture. It is thought to be the parent, along with Crataegus succulenta, of the tetraploid species Crataegus persimilis.
Mangifera indica, commonly known as mango, is an evergreen species of flowering plant in the family Anacardiaceae. It is a large fruit tree, capable of growing to a height of 30 metres. There are two distinct genetic populations in modern mangoes – the "Indian type" and the "Southeast Asian type".
Elaeocarpus bancroftii, commonly known as Kuranda quandong, Johnstone River almond, ebony heart, grey nut, or nut tree is a large rainforest tree in the family Elaeocarpaceae which is endemic to Queensland. It has coriaceous leaves, attractive white flowers and relatively large fruit containing an edible kernel.
Senna italica, the Port Royal senna, Italian senna, or Senegal senna is a legume tree in the genus Senna. It is recognized by many other common names based on the regions it grows in. In India, it is used to produce a powder for treating hair-related diseases which is known as “neutral henna”. Whereas, in some parts of the world, this species is cultivated for the leaves which yield the drug senna, known commonly as Senna glycoside, which in turn is the base for a laxative. Senegal senna is easily distinguishable through its many distinctive features. There are 3 subspecies of this plant based on the size of the inflorescence and the length of the petiole. The subspecies are italica, micrantha, and arachoides. In many regions, this plant is cultivated commercially and medicinally.
Dianthus monspessulanus, the fringed pink, is a herbaceous perennial plant of the genus Dianthus of the family Caryophyllaceae. The genus name Dianthus derives from the Greek words for divine ("dios") and flower ("anthos"), while the species name monspessulanus means "from Montpellier".
Evolvulus alsinoides, commonly known as dwarf morning-glory and slender dwarf morning-glory, is flowering plant from the family Convolvulaceae.

It has a natural pantropical distribution encompassing tropical and warm-temperate regions of Australasia, Indomalaya, Polynesia, Sub-Saharan Africa and the Americas.

It is classified in the rose family, Rosaceae, and is one of several species whose fruit are called apricot, although this species is rarely cultivated for its fruit. The species was named by Carl Linnaeus in 1753.
Cola nitida is a species of plant belonging to the family Malvaceae.

Myristica insipida, commonly known in Australia as Australian nutmeg, Queensland nutmeg or native nutmeg, is a small rainforest tree in the family Myristicaceae native to parts of Malesia, Papuasia and Australia. It is closely related to the commercially-important species of nutmeg, M. fragrans.
Diospyros paniculata, or the panicle-flowered ebony, is a species of tree in the ebony family. Endemic to the Western Ghats area of India and parts of Bangladesh, the species is currently listed as Vulnerable in the IUCN Red List.
Ourisia integrifolia or mountain whitebell is a species of flowering plant in the family Plantaginaceae that is endemic to Tasmania, Australia. Robert Brown described O. integrifolia in 1810. Plants of this species of Australian foxglove are showy, perennial, rhizomatous herbs that are mostly glabrous but can have some non-glandular hairs. They have crenate or notched, ovate to broadly ovate leaves. The flowers are usually single or in pairs in each node in the inflorescence, with a regular calyx, and a white sub-regular corolla. The corolla tube is yellow with and glabrous inside.
