Common name: Tasmanian Bladderwort
Utricularia monanthos Hook.f. APNI*
Description: Terrestrial perennial herb.
Leaves linear or very narrow-elliptic, to 3 cm long, to 1 mm wide.
Traps on the root-like stems; globose, 1–2 mm long; mouth lateral. Raceme erect, solitary, 1–4 cm long, 1- or rarely 2-flowered; scales absent; bracts and bracteoles similar; basifixed, c. 1.5 mm long. Calyx lobes unequal, broadly oblong-elliptic to ovate, c. 3 mm long. Corolla 6–10 mm long, deep violet; lower lip marked with yellow and 3 conspicuous violet ridges; spur broad-conical, much shorter than lower lip.
Distribution and occurrence: Grows in very wet soils or shallow water by mountain streams and pools, south from Kiandra-Kosciusko area.
NSW subdivisions: NT, ST
Other Australian states: Vic. Tas.
Material from Barrington Tops has spurs longer than the lower lip. Taylor (1989) suggests that the possibility that U. monanthus is a high-elevation variant of U. dichotoma needs further investigation.
