Utricularia lateriflora R.Br.

"Flowering-stem simple, slender, erect, 2-4 inches high. Leaves few, at the base of the stem, spathulate, mostly about 2 lines long. Flowering-stem bearing 2 or 3 minute, empty, distant bracts, besides those subtending the flowers. Flowers nearly sessile, usually 3-6, solitary at intervals along the stem, but often only 1, and then terminal. Calyx-lobes about 1 line long, obtuse. Corolla lilac to purple, about 3 lines long; upper lip narrow, erect, about 1-11/2 line long; lower lip directed forwards, ending abruptly, raised in the centre, and bearing a conical spur beneath (running forwards, and as long as the lip). Stamens short. Anthers connate in front of the very short style."
