. opposite, subsessile, elliptic or broadly lanceolate (1.5-5.0 cm X 0.5-2 cm)
· gradually yellow and fall during prolonged dry or cool intervals.


Henna Flowers
· borne in large terminal panicled cymes and are numerous, small, white or rose-coloured and fragrant.
· have four sepals and a 2 mm calyx tube with 3 mm spread lobes. Petals are obvate, white or red stamens inserted in pairs on the rim of the calyx tube. Ovary is four celled, style up to 5 mm long and erect.

Henna Fruits

. are small , 4-8mm in diameter, capsular and nearly globose, about the size of pea with numerous smooth, pyramidal seeds (with 32-49 seeds per fruit)

Anatomy

General
-occurrence of intraxylary phloem where the vascular bundle is in the form of bundles

Leaf
· Epidermis containing mucilaginous cells. The tabular epidermal cell are rectilinear or tend to be polygonal in surface view..
· Mesophyll dorsiventral with 2 or more layers of palisade tissue towards the upper surface. But locally isobilateral owing to the tendency for the outer cells of the spongy mesophyll to develop as a second palisade.
· Storage and terminal tracheids occur in the form of large pitted cells
· Crystals – presence of small crystalline rod, needles or granules


Stem
· young stem commonly with 4 or 5 prominat angles and sometimes enlarged to form wing-like expansion.
· Cork arising arising in the inner part of the pericycle. Partly composed of phelloid cells
· Presence of intraxylary phloem


Propagation / Reproduction

Sexual – by seeds
Asexual – by cutting


Habitat, origin and geography.

· Henna will only grow where minimum temperatures stay above 11⁰C. It will tolerate extreme heat and long droughts. It grows wild near desert oasis, and in semi-aid regions. It thrives in alluvial soils, where there is annual precipitation of 0.2 to 4.2 meters and a soil pH of 4.3 to 8.0 (4.1-31). hot, semi-arid regions.

· Country of Origin: northern Africa, southwestern Asia.

· Now is extensively grown in India, Egypt, Sudan, Iran, Malagasy Republic, Pakistan and Australia

· It is grown all over India as hedge plant., but it is cultivated as a dye crop mainly in Haryana, Punjab and Gujarat.

· Henna use and its traditions have migrated over the course of many centuries as the people of the world's henna-using cultures moved across parts of Asia, Africa, and Europe. The pace of that migration has increased greatly as people from southern Asia and the Middle East have formed permanent communities in the West and fast efficient shipping and commmunication have made it possible to transport henna and information about it to all parts of the world.

Properties

Henna, Lawsonia inermis, contains a red-orange pigment, lawsone(C10H6O3) ; 1.0-1.4% occurring in the dried leaves. The molecule is also known as hennotannic acid. When henna leaves are crushed in an acidic medium and applied to skin, the lawsone molecules migrate from the henna paste, traverse the outermost layer of the skin, Stratum corneum and stain the skin. Prolonged applications of henna result in diffusion of the pigment deeply into the skin. It is harmless and causes no irritation of the skin. Chemically, the molecule of lawsone is 2-hydroxy-1, 4-naphthoquinone. Industrial classifications also describe lawsone as Natural Orange 6 and C.I. 75480. The name and molecular structure of lawsone show its congeniality to naphthalene. In lawsone, two oxygen atoms are attached to the naphthalene carbons at positions 1 and 4 to form 1,4-naphoquinone and a hydroxyl (–OH) group is present at position 2. Its molecule contains 10 carbons, 6 hydrogens and 3 oxygens (C10H6O3), giving a total molecular weight of 174.16 atomic units of mass. Pure lawsone is an orange powder, insoluble in water, with a melting point higher than 192ºC and optical absorption maximum of 452 nm.

Uses of Henna

Henna has many traditional and commercial uses, the most common being as a dye for hair, skin and fingernails, as a dye and preservative for leather and cloth, and as an anti-fungal. It is also
