Morphology General Habit
Perennial herb or subshrub 0.3–1.8 m. tall, with thick tuberous root to 45 cm. long; stems annual, erect, at first densely velvety adpressed hairy but sometimes becoming almost glabrous.
Morphology Leaves
Radical and lower stem-leaves elliptic-ovate to ovate, 10–27 cm. long, 3.5–17 cm. wide, acuminate at the apex, rounded, cuneate or subcordate at the base, short-to long-decurrent into the 9–42 cm. long petiole, sparsely hairy on both faces; stem-leaves sessile or decurrent and shortly petiolate, elliptic-lanceolate to ovate, 2–18 cm. long, 1.6–10 cm. wide, acuminate at the apex, rounded at the base, above ± subscabrid to less often distinctly scabrid with tubercle-based hairs surrounded by cystoliths, ± velvety hairy beneath, becoming almost glabrous or with sparse hairs on the raised and reticulate venation; petiole 0–2 cm. long.
Morphology Reproductive morphology Inflorescences
Inflorescences terminal and axillary, the cymes very short, ± 1 cm. long at first, rapidly elongating to 6–12 cm. in fruit; pedicels 2–5(–10) mm. long, lengthening and reflexing in fruit to 1–2.5(–3.5) cm.; all axes adpressed pubescent to velvety, sometimes yellowish in dry state.
Morphology Reproductive morphology Flowers Calyx
Sepals broadly elliptic to ovate, 1.5–2.5(–4) mm. long, 1.5–1.7(–3.5) mm. wide, ± acute, accrescent to 5 × 4.5 mm. in fruit, pubescent and ciliate outside, glabrous inside.
Morphology Reproductive morphology Flowers Corolla
Corolla light to dark blue, sometimes reddish purple at first and persistently at throat; tube 1.3–2.6 mm. long; lobes broadly elliptic to round or oblate, 1.3–2.5(–4) mm. long, 1.8–3.2(–5) mm. wide; throat-bosses ± square, papillate; filaments 0.2–0.3 mm. long; anthers 0.7–1 mm. long.
Morphology Reproductive morphology Flowers Gynoecium Ovary
Ovary ± 1 mm. long; style 0.5–1.2 mm. long; stigma terminal, globose, bilobed.
Morphology Reproductive morphology Fruits
Fruit 0.8–1.5 cm. wide; nutlets cushion-shaped, depressed, 5–6 mm. wide, the external ± convex face uniformly covered all over with short stout conic glochidia or only around the margins and along a median line.

Morphology General Habit
A rhizomatous perennial herb 0.8–1.8(3.5) m. high, much branched, with shortly and retrorsely hispid often reddish annual stems.
Morphology Leaves
Inferior leaves petiolate, the superior ones sessile; petiole up to 13(42) cm. long, with sheathing base; lamina of the inferior leaves 12–20 x 7–12 cm., becoming progressively smaller to the apex, ovate or less often elliptic, shortly and sparsely hispid on both surfaces, acute at apex and sometimes apiculate, obtuse to subcordate at base and suddenly decurrent on the petiole.
Morphology Reproductive morphology Inflorescences
Inflorescence of short racemes arranged in terminal bracteate panicles; bracts ovate to lanceolate, acute.
Morphology Reproductive morphology Flowers
Flowers with pedicels 2–4 mm. long.
Morphology Reproductive morphology Flowers Calyx
Calyx appressed-pubescent outside, glabrous inside; lobes 1.0–2.5 x 1.2–1.7 mm., elliptic to very widely ovate, subacute to rounded at apex.
Morphology Reproductive morphology Flowers Corolla
Corolla usually blue, often with reddish throat, sometimes the whole whitish; tube 1.4–1.6 mm. long, slightly infundibuliform; limb 4–6 mm. in diam.; lobes 1.4–2.4 x 1.0–2.6 mm., very widely ovate to depressed-ovate, obtuse, much veined.
Morphology Reproductive morphology Flowers Androecium Stamens
Stamens inserted at 0.6–1.0 mm. from the base of the corolla tube; anthers 0.6–0.7 mm. long, elliptic-oblong, obtuse, subcordate at base; filaments 0.3–0.5 mm. long.
Morphology Reproductive morphology Flowers Gynoecium Pistil
Ovary c. 1 mm. in diam.; style overlapping the ovary by 0.3–0.6 mm.; stigma globulose, terminal.
Morphology Reproductive morphology Fruits
Fruits 10–12 mm. in diam., on usually reflexed pedicels up to 17 mm. long; nutlets 5–6 mm. in diam., free from the style, with the outer surface convex and ± uniformly covered with 0.5–0.6 mm. long glochids.
