    Inflorescences
    Racemes terminal and leaf-opposed, long-pedunculate, up to 8–16 cm. long, with few to many laxly arranged flowers; bracts subulate, 1–2 mm. long; bracteoles inserted at the base of the calyx, less than 1 mm. long.
    Calyx

    Seeds
    Seeds oblique-cordiform, 2·5–3 mm. long, often slightly rugulose, reddish-brown.
