Synonyms: Utricularia inflexa Forsk. var. stellaris (L. f.) P. Taylor
Common names:
Status: Native
Aquatic canivorous herb. Stolons up to 1 m × 2.5 mm, internodes 5-20 mm. Leaves numerous, digitately divided into 3-6 primary segments, 1-6 cm long, repeatedly forked again into filiform segments. Traps numerous on the ultimate and penultimate leaf segment, broadly ovoid, shortly stalked, 1-3 mm long. A whorl of inflated floating leaves present on the upper half of the inflorescence peduncle, 0.5-20 mm long, ellipsoid, 2-4 times as long as wide, with a few reduced leaf-segments at the apex. Inflorescence 3-30 cm long, 2-16-flowered. Corolla 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 calyx lobe; spur cylindrical, more or less as long as the lower lip. Fruit a globose capsule, c.5 mm in diameter.
Notes: The combination of a whorl of short, ellipsoid floating leaves on the inflorescence peduncle and yellow flowers easily distinguishes this species.
