Senna glutinosa is a species of flowering plant in the family Fabaceae and is endemic to central and northern arid areas of Australia. It is a shrub or small tree with pinnate leaves with up to seven pairs of leaflets, their shape depending on subspecies, and yellow flowers arranged in groups with ten fertile stamens in each flower.

Description

Senna glutinosa is a more or less glabrous, erect or straggling shrub or small tree, that typically grows to a height of 0.3–4 m (1 ft 0 in – 13 ft 1 in), its stems, leaves and outer flower parts sticky. The leaves are pinnate with up to seven pairs of leaflets spaced more than 6 mm (0.24 in) apart, on a petiole more than 6 mm (0.24 in) long, the size and shaped of the leaflets varying with subspecies. The flowers are yellow and arranged in groups near the ends of branches, the sepals oval, 8–10 mm (0.31–0.39 in) long and greenish-yellow. The petals are oval, 11–15 mm (0.43–0.59 in) long and there are ten fertile stamens in each flower, the anthers 4–5 mm (0.16–0.20 in) long. The fruit is a flat pod 50–70 mm (2.0–2.8 in) long and 10–20 mm (0.39–0.79 in) wide. [2] [3]

Taxonomy

This species was first formally described in 1825 by Augustin Pyramus de Candolle who gave it the name Cassia glutinosa in his Prodromus Systematis Naturalis Regni Vegetabilis . [4] [5] In 1989, Barbara Rae Randell transferred the species to the genus Senna as S. glutinosa in the Journal of the Adelaide Botanic Gardens . [6] [3] The specific epithet (glutinosa) means "sticky", referring to the stems, leaves and pedicels. [7]

In the same journal, Randell described four subspecies of S. glutinosa, and the names are accepted by the Australian Plant Census:

Distribution and habitat

Senna glutinosa grows in arid shrubland in all mainland states of Australia and the Northern Territory, but not in Victoria. Subspecies chatelainiana in the central west of Western Australia, [9] [17] and subsp. glutinosa from the north-west of Western Australia to the Northern Territory and north-western South Australia. [11] [18] Subspecies × luerssenii occurs from the central coast of Western Australia to near the Northern Territory border, [13] [19] and subsp. pruinosa is found from north-western Western Australia to far northern South Australia, and far western Queensland and New South Wales. [15] [16] [20]

Conservation status

All four subspecies of S. glutinosa are listed as "not threatened" by the Government of Western Australia Department of Biodiversity, Conservation and Attractions. [17] [18] [19] [20]
