There are four stamens of unequal length inserted on the base of the corolla Fig. 140.
Calyx inferior, funnelform, with 4–5 sepals as long as the corolla.
The calyx is deeply divided, and the limbs of the corolla are spreading.
corolla, 5–6 petals, inserted on the calyx, curved downward.
Calyx of same color as corolla, inferior, very small, 4-lobuled.
