Leaves dark green, tough, very narrowly oblanceolate, up to 40 cm. long and 5.5 cm. wide, acute at the apex, narrowing below into a petiole-like base, glabrous; margin ± revolute, coarsely dentate or doubly dentate with teeth up to 5 mm. long and 10 mm. wide, venation protruding beneath, the lateral veins almost perpendicular to the midvein and weakly arcuate.. Inflorescence ± 2 m. long, branched with a terminal densely many-flowered raceme supplemented by about a dozen rather densely crowded axillary racemes on leafy peduncles; pedicels 5–8 mm. long, spreading-papillose, ebracteolate; bracts oblanceolate, ± 30 mm. long, papillose..
