Original diagnosis/description

Spathes 5–12 mm long x 3–8 mm wide, grown out from the scape 18–40 mm long x 0.8–1.2 mm wide, elliptical-ovate to obovate, striate with parallel veins; bulbils sessile, 1 mm long x 0.2 mm wide produced apically; flowers campanulate, pedicellate, pedicels 2–8 mm long x 0.5–1.0 mm wide, corolla lobed with 3–4 lobes obvious, 4–8 mm long x 3–6 mm wide.

Etymology

The species epithet, billgenseli, honors the late botanist and horticulturalist William H. Gensel (Durham, NC) for his contributions to the plant sciences and for recognizing the similarities of the fossils to modern Allium and other bulbforming monocots.
