Morphology Reproductive morphology Flowers Perianth
Perianth-limb trumpet- or funnel-shaped, very delicate, white, pink, magenta or purple
Morphology Reproductive morphology Flowers Androecium Stamens
Stamens 2–6, unequal, exserted
Morphology Reproductive morphology Fruits
Anthocarp fusiform or clavate, obscurely 10-ribbed/grooved, glabrous, with 1–several whorls of large, dark, very sticky gland-warts, those near the apex sometimes stalked.
Distribution
