Lawsonia inermis 0.5–2 cm or 0.6–2 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 calyx tube, with spread lobes. Its petals are obvate, with white or red stamens found in pairs on the rim of the calyx tube. The ovary is four-celled, long, and erect. Henna fruits are small, brownish capsules, in diameter, with 32–49 seeds per fruit, and open irregularly into four splits. The henna plant is native to northern Africa, western and southern Asia, and northern Australia, in semi-arid zones and tropical areas.
Cliffortia have arisen at four independent occasions. Trimerous flowers have three sepals of variable size, and in male flowers six to many stamens. Tetramerous flowers have four sepals of 5 mm long at most and either four or eight stamens. In female flowers the sepals are united at their base to form a calyx tube, and have one or two styles, that are finely divided like an ostridge feather. One or two achenes may develop in each flower, within the inflating calyx. The first who mentioned species that are currently assigned to "Cliffortia" was Leonard Plukenet in 1696.
