Senna barclayana, commonly known as smooth senna or pepper-leaf senna, [2] is a species of flowering plant in the family Fabaceae and is endemic to eastern Australia. It is a herbaceous perennial or subshrub with pinnate leaves with six to ten pairs of lance-shaped or narrowly elliptic leaflets, and yellow flowers in groups of six to ten.
Senna barclayana is an erect, herbaceous perennial subshrub that typically grows to a height of up to 1.5 m (4 ft 11 in). Its leaves are pinnate, 80–120 mm (3.1–4.7 in) long on a petiole 10–20 mm (0.39–0.79 in) long, with six to ten pairs of lance-shaped or narrowly elliptic leaflets 20–50 mm (0.79–1.97 in) long and 4–9 mm (0.16–0.35 in) wide. There is a sessile gland near the base of the petiole, and a stipule that falls off as the leaf opens. The flowers are yellow and arranged in upper leaf axils in pairs or groups of six to ten on a peduncle 20–35 mm (0.79–1.38 in) long, each flower on a pedicel 12–20 mm (0.47–0.79 in) long. The petals are up to 20 mm (0.79 in) long and there are six fertile stamens and four staminodes, the longest anthers about 3 mm (0.12 in) long. Flowering occurs all year, and the fruit is a cylindrical pod 30–50 mm (1.2–2.0 in) long. [2] [3] [4]
This species was first formally described in 1827 by Robert Sweet who gave it the name Cassia barclayana in his Flora Australasica . [5] [6] In 1988, Barbara Rae Randell transferred the species to Senna as Senna barclayana in the Journal of the Adelaide Botanic Garden . [4] [7] [4] The specific epithet (barclayana) honours Robert Barclay of Bury-hill (1751–1830). [6] [8]
Senna barclayana grows in open forest southern Queensland and northern New South Wales, but its range is increasing and it is now naturalised in Victoria, South Australia and Western Australia. [2] [3] [9]
Robert Sweet was an English botanist, horticulturist and ornithologist.
Senna, the sennas, is a large genus of flowering plants in the legume family. This diverse genus is native throughout the tropics, with a small number of species in temperate regions. The number of species is estimated to be from about 260 to 350. The type species for the genus is Senna alexandrina. About 50 species of Senna are known in cultivation.

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.
