Perennial (or possibly sometimes annual) herb to 1.8 m. tall from a thick tap-root; stems strict and sparsely branched, often streaked with purple above.
Morphology Leaves
Leaves narrow and elongate; radical leaves oblanceolate, up to ± 30 cm. long, 3.5 cm. wide, narrowly acute at the apex, strongly attenuated at the base so as to appear long-petiolate; cauline leaves lanceolate to oblong-lanceolate, 4–20 cm. long, 0.7–2 cm. wide, the uppermost sessile, the lower gradually more attenuate until similar to radicals; both surfaces sparsely to fairly densely covered with white hairs arising from cystolith spots.
Morphology Reproductive morphology Flowers
Flowers in long-pedunculate well-branched compound dichasia of scorpioid cymes which in the early stages are ± capitate and distinctive; cymes ultimately ±12 cm. long; peduncles up to 16 cm. long; pedicels 1.5–3 mm. long; all axes densely white pubescent.
Morphology Reproductive morphology Flowers Calyx
Calyx-lobes oblong-elliptic, 2–3 mm. long, ± 1 mm. wide, distinctly ciliolate, pubescent outside with hairs from tubercular cystolith bases, very distinct near base.
Morphology Reproductive morphology Flowers Corolla
Corolla deep blue, white at throat, rarely all white; tube 2.5–3.5 mm. long; lobes ± round, 2–4 mm. long and wide; style (1.3–) 1.8 mm. long to over 2 mm. long in fruit, slender.
