Stipules 3–13 mm. long; apex lacerated.. Peduncles 1–4, 8–30 cm. long, arising laterally from the stem, then curving to become erect, canaliculate, glabrous; inflorescence racemose, 3–13-flowered; pedicels 2–10 mm. long, glabrous or sparsely pilose; bracts linear to elliptic, 3–5 mm. long, caducous..
