Inflorescence: bractlets < calyx. Flower: calyx 1--2 cm, generally 5-lobed, split to base on lower side, or sepals free; corolla 2--5 cm, bell- to funnel-shaped, showy, tube cylindric, generally < 1 cm, bent downward, throat 10--30 mm, limb with 5 flared lobes, throat and lower limb with colored lines (nectar guides).
