Star Bladderwort is an aquatic canivorous herb. Inflorescence is 3-30 cm long, 2-16-flowered. A whorl of inflated floating leaves present on the upper half of the inflorescence flower-cluster-stalk, 0.5-20 mm long, ellipsoid, 2-4 times as long as wide, with a few reduced leaf-segments at the tip. Flowers are 2-lipped, 7-10 mm long, yellow, often with reddish lines on the palate; upper lip broadly ovate, 1.5-2 times as long as the upper sepal; spur cylindrical, more or less as long as the lower lip. The combination of the whorl of floating leaves on the inflorescence flower-cluster-stalk and yellow flowers easily distinguishes this species. Stolons are up to 1 m x 2.5 mm, internodes 5-20 mm. Leaves are numerous, digitately divided into 3-6 primary segments, 1-6 cm long, repeatedly forked again into thread-like segments. Traps are numerous on the ultimate and penultimate leaf segment, broadly ovoid, shortly stalked, 1-3 mm long. Fruit is a spherical capsule, about 5 mm in diameter. Star Bladderwort is found in Africa, Indian Subcontinent to Indo-China, N. Australia.
