Nov. Holl. Pl. 1: 50, t. 71 (1805) APNI
Erect succulent or semi-succulent glabrous annual 10–60 cm high, often red-tinged; stems solitary or several from the base. Leaves linear to narrowly oblanceolate, rarely narrowly lanceolate, 3.5–35(–65) mm long, 0.2–2 mm wide, usually reduced towards inflorescence, entire and withered at anthesis; petiole indistinct. Flowers bisexual, in terminal and sometimes axillary 2–10-flowered, 1-sided racemes, axis often sinuous; pedicels 2–9 mm long, glabrous. Calyx-lobes 3–5 mm long, entire; corolla 2-lipped, 10–20 mm long, blue, upper 2-lobes short, strongly recurved, lower 3 lobes spreading, rarely decurved, narrowly elliptic, oblanceolate, narrowly lanceolate or oblong, the central lobe longest, 4–9 mm long, 1–3.5 mm wide, usually narrowly elliptic, acute, lateral lobes falcate, tube 4–9 mm long, split virtually to base, papillose to minutely pubescent internally mainly along central channel; filaments 4–6.5 mm long, anther tube 2.4–4 mm long. Capsule obliquely obovoid to obliquely obconical, 5–12 mm; seeds brown, ellipsoid long to oblong, usually irregularly angular, 0.2–0.3 mm long, reticulate. Flowers Oct.–Mar.

A remarkable feature of this taxon is that uprooted specimens remain turgid and even produce flowers for up to a month or so after collection. Western Australia populations presently referred to Lobelia gibbosa var. gibbosa require further study as the seeds are not obviously reticulate.
