Senna gaudichaudii, also known by many common names, including kolomana in Hawaii[2] and as blunt-leaved senna in Australia, is a species of flowering plant in the family Fabaceae and is native to some Pacific Islands including Hawaii, parts of Southeast Asia and Queensland in Australia. It is shrub or small tree with pinnate leaves, usually with three to five pairs of oblong to egg-shaped leaflets, and yellow flowers arranged in groups of four to ten, with ten fertile stamens in each flower.
Description
Senna gaudichaudii is a shrub or tree that typically grows to a height of 2–3 m (6 ft 7 in – 9 ft 10 in), sometimes a tree-top vine. Its new growth is sometimes covered with soft, golden-yellow hairs. The leaves are pinnate, 50–100 mm (2.0–3.9 in) long on a petiole 10–30 mm (0.39–1.18 in) long, usually with three to five pairs of oblong to egg-shaped leaflets, the narrower end towards the base. The leaflets are mostly 20–50 mm (0.79–1.97 in) long and 7–15 mm (0.28–0.59 in) wide, usually spaced 6–10 mm (0.24–0.39 in) apart. There are up to three stalked glands between the lowest pairs of leaflets. The flowers are yellow and arranged in upper leaf axils in groups of four to ten on a peduncle 30–50 mm (1.2–2.0 in) long, each flower on a pedicel 20–30 mm (0.79–1.18 in) long. The petals are 10–15 mm (0.39–0.59 in) long and there are ten fertile stamens, the anthers about 5–7 mm (0.20–0.28 in) long. Flowering occurs from February to October in Australia, and the fruit is a flat pod 100–150 mm (3.9–5.9 in) long, about 10 mm (0.39 in) wide and slightly curved.[2][3][4]
This species is also known by the common names kolomana, kalamona, keuhiuhi, uhiuhi[2] and heuhiuhi[7] in Hawaii, and as climbing senna and Gaudichaud's senna in Australia.[3]
