Senna heptanthera is a species of flowering plant in the family Fabaceae and is endemic to Arnhem Land in the north of the Northern Territory. It is a creeping, herbaceous perennial with pinnate leaves with one or two pairs of broadly egg-shaped leaflets, and yellow flowers arranged in groups of eight to ten, with seven fertile stamens in each flower.
Senna heptanthera is a creeping, herbaceous perennial that has leaves up to 60 mm (2.4 in) long on a petiole up to 30 mm (1.2 in) long. The leaves are pinnate with one or two pairs of broadly egg-shaped leaflets, 20–50 mm (0.79–1.97 in) long and 20–40 mm (0.79–1.57 in) wide, spaced up to 30 mm (1.2 in) apart. There is a single, sessile gland between the lowest pair of leaflets. The flowers are yellow and usually arranged in groups of eight to ten in upper leaf axils on a peduncle 30–60 mm (1.2–2.4 in) long, each flower on a pedicel up to 15 mm (0.59 in) long. The petals are up to 10 mm (0.39 in) long and there are seven fertile stamens in each flower, the anthers about 4 mm (0.16 in) long. Flowering occurs in February and March and the fruit is a flat pod. [2]
This species was first formally described in 1876 by Ferdinand von Mueller who gave it the name Cassia heptanthera in Fragmenta Phytographiae Australiae, from specimens collected near the Liverpool River. [3] [4] In 1989, Barbara Rae Randell transferred the species to the genus Senna as Senna heptanthera in the Journal of the Adelaide Botanic Gardens. [5]
Senna heptanthera occurs in northern Arnhem Land. [2] [6]
