Prostrate dioecious perennial herb with branches hairy and often with adventitious roots; leaves sessile or almost so, lanceolate, ovate to almost orbicular, 4-13 x 3-7 mm, bluntly acute, with few widely spaced teeth each somewhat thickened, short-hairy.

Flowers usually only a few borne singly in the axils of leaf-like bracts towards the end of branches; male flowers abruptly constricted into a peduncle, with more or less aborted ovary; female flowers without pollen in the pale anthers; peduncle 15-50 mm long; sepals scarcely connate, the lobes linear-triangular, 1.5-2.5 mm long, usually clasping the corolla tube; corolla 5-8 mm long, the pale basal tube split along the upper side, the linear-oblanceolate lobes spreading, a deep bluish-purple with more or less white around the throat, glabrous; anther-column with spreading blunt hairs on the upper surface of the upper cells.

Fruit obovoid, 4-5 mm long; seeds ellipsoid but somewhat laterally compressed, c. 0.5 mm long, sometimes ridged on one side, finely pitted.

Taxonomic notes: Dried material of some forms of Isotoma .fluviatilis subsp. australis is often confused with this species but is generally more robust and has hairs inside the corolla tube. The distinguishing characters between P. pedunculala and P. puberula are discussed under the latter species.
