The five petals are fused tube- to funnel-shaped. The corolla tube is straight or curved. The corolla tube ends two-lipped. The upright upper lip is more than slightly bilobed. The back sometimes curved lower lip is three-lobed. The color of the petals ranging from white or yellow to orange to red. The four fertile stamens protrude from the crown or are shorter than the lower lip. Two carpels are a superior ovaries fused with two ovules per ovary chamber. The long style ends in a most weakly bilobed scar. Pollination is by birds ( Ornithophilie ).

The zweifächerigen capsule fruits contain four seeds. The seeds are silky hairs. The distribution unit ( diaspore ) is the seed.
