Bulb rhizomatous, ovoid, 4–6 × 2–4 cm; basal plate 2–3 cm; neck 2–5 cm; tunic grayish brown. Leaves deciduous, 3–7, arching, reflexed at apex, 2–5.5 dm × 1–1.8(–2.5) cm, longest leaf exceeding 4 dm at anthesis, coriaceous; blade shiny green, narrowly liguliform, channeled proximally, apex acute. Scape 3.5–5 dm, 2-edged, glaucous; scape bracts 2, enclosing buds, 4–5.5(–6.5) × 1–1.5 cm; subtending floral bracts 2.5–5 cm × 4–8 mm.

Discussion
Little information about Hymenocallis tridentata was available before a study by A. Herndon (1987), who contrasted its traits (under the name H. floridana) with those of H. palmeri, remarking that as one proceeds northward, the plants bearing two flowers show an increase in floral size. Additional study is needed to further resolve the distribution of H. tridentata and to clarify its relationship to H. rotata. Our data indicate that H. tridentata is distinctly smaller than H. rotata in all features.
