    • 2b. Perianth open-campanulate; tepals 15–25 mm long, connate for less than their length; leaf blades 10–20 mm wide; racemes with usually 4–10 flowers, open, without apical sterile flowers
  • 1b. Tepals essentially distinct (i.e., connate for less than 1⁄10 their total length) [Fig. 128]; stamens free or inserted near the base of the tepals
