Racemes cylindric slightly acuminate, very densely multiflowered, 35-45 cm long, 5-6 cm diam., usually terminating in a small tuft of wilted brownish bracts, the buds and flowers spreading downwards. Brads lanceolate-acute, 14 mm long, 7 mm broad, thin scarious brownish, many-nerved, very reflexed. Pedicels green, 3 mm long. Perianth bright red above, the underside lemon, curved-cylindrical, up to 50 mm long, the base rounded, not stipitate, about 7 mm diam., enlarging to about 9 mm above the middle thence slightly narrowing to the mouth, somewhat laterally compressed; outer segments connate into a tube for 30 mm, the free portion 20 mm, the 2 upper segments scarlet, with 5 reddish nerves turning slightly brownish at apex, the margins paler, the apices sub-acute and slightly falcately connivent, the lowest segment lemon, with 3-5 deeper lemon nerves, the apex sub-acute, straight; inner segments free but dorsally adnate to the outer to about the middle, with thin white margins; the uppermost segment with a 20 mm keel the colour of the perianth turning brownish at apex; the 2 lowest segments with a less pronounced keel formed by 3 crowded, greenish nerves.
