    Habit
    Prostrate perennial herb about 40 cm. long from a large tuberous root 20 cm. long, 6 cm. wide, beginning to flower just before the leaves appear or whilst they are very young.
    Stem
    Stems mostly simple, zigzag, covered with spreading white hairs.
    Leaves
    Leaves unifoliolate; leaflet elliptic to elliptic -lanceolate, 4·5–18 cm. long, 1·5–8 cm. wide, acute at the apex, rounded to almost subcordate at the base, pubescent on both surfaces but particularly on the nerves beneath, 3–5-nerved from the base, but other lateral nerves obscure the effect, so that the leaflet is not so characteristically 3-nerved as in other species; petiole 3–7 mm. long; stipules ovate to lanceolate, 1–2·5 cm. long, 0·2–1 cm. wide, forming conspicuous bracts for the fascicles of flowers in young shoots, glabrous or almost so but margins ciliate, veined.
    Flowers
    Flowers numerous in axillary fascicles; rhachis attaining 2·5 cm.; pedicels 1–4 cm. long, pilose; bracteoles minute, linear.
    Calyx
    Calyx with spreading white hairs; tube ± 3 mm. long; lobes triangular, 1·5–3 mm. long, the upper pair joined for ± three-quarters of their length to form a bifid lobe.
