Generative characteristics
The small, 3–7.5 cm wide,[5] white or rosy,[6] flowers have peduncles with 4 primary air canals.[6] The sepals are green. The 8–17 petals are white.[3] The filaments are widest above the middle of the filament.[2] The gynoecium consists of 5–12 carpels. The fruit bears smooth, ovoid, 2–3 mm long, and 1.5–2 mm wide seeds.[3]
