Tuber less elongated than that of D. divaricata but in general similar. Plant glabrous. Stem armed at the base, firm, very indistinctly ridged. Bulbils none seen. Leaves opposed as a rule, mostly ovate with the base if not rounded somewhat truncate, but the larger leaves are hastate, acuminate, as a rule about 9 by 2 cm, but at times to 20 by 9 cm, 7-nerved; petiole to 4 cm. Male flowering axes 1-3 together, aggregated on rather long leafless branches which attain 20 cm in length, or at times in axillary fascicles; axis angled, to 6 cm long with about 40 flowers spaced their own diameter apart. Buds globose above a broad base, 1 mm long. Female flowering axes to 14 cm long or longer, angled. Capsules apparently exactly as those of D. divaricata.
