1a. Ovary and fruit bilocular, the fruit 2.8–4.5 mm long; rhizomes slender; flowers borne on spreading pedicels [Fig. 738], opening after elongation of the raceme axis, therefore the inflorescence relatively open; petals (1.3–) 1.6–3.9 mm long; anthers (0.5–) 0.7–1 mm long; plants 15–70 (–100) cm tall
1b. Ovary and fruit unilocular, the fruit 1.6–2.6 mm long; rhizomes tuberous-thickened at the end; flowers borne on ascending to erect pedicels, beginning to open prior to elongation of raceme axis, therefore the inflorescence congested near the apex; petals 0.6–2 mm long; anthers 0.2–0.3 mm long; plants 5–25 (–30) cm tall
