Acaulescent rosettes 70–80 (–90) cm tall including the inflorescences at full development, branches sometimes not completely prostrate but rising laterally from the apical nodes of the main plant, each stem supporting a single terminal inflorescence. White velutinous indumentum covering much of the plant as stems, petioles, stipules, scape and pedicels. Free stipule tips lanceolate and flexuose, 20–33 (–46) × 1.4–4.4 (–5) mm; leaflets narrowly elliptic, up to (8–) 10.1–12 cm × 2.5 (–3) cm, secondary venation gradually diminishing towards the margin of the lamina. Inflorescences with 27–29 crowded whorls of 8–10 flowers per whorl; pedicels 2–2.9 mm long; corolla with the standard petal with a white vertical blotch in the centre covering almost one third of the width.
