Details of the flower (e.g., tepal color, tepal shape, flower orientation) are often distorted or obscured in pressing. Noting these features on herbarium labels will assist with identification at a later date. Reference: Skinner (2002).

  • 1a. Leaves alternate throughout, with bulbils in the upper axils; mature buds evenly tapering to a ± flat apex with 3 green, apical, rounded processes
  • 1b. Leaves mostly or all whorled, without axillary bulbils; mature buds not as above
    • 2a. Flowers erect; tepals with a distinct, abruptly narrowed, basal portion [Fig. 157]; inflorescence with 1–3 flowers
    • 2b. Flowers nodding; tepals gradually narrowed in the basal portion; inflorescence 
with (1–) 2–22 flowers
      • 3a. Style similar in color to the tepals; tepals merely somewhat recurved, the outer tepals lacking abaxial ridges; buds round in cross-section; margins and veins of leaf blades roughened on the abaxial surface with triangular epidermal spicules
      • 3b. Style pale green; tepals strongly recurved, forming a “Turk’s-cap” perianth, the outer tepals with 2 faint, abaxial ridges; buds triangular in cross-section; margins and veins of the leaf blades not roughened on the abaxial surface
