The leaves are opposite, simple oval, 1–5 cm long and 0.5–2 cm broad, varying from glossy green to tomentose grey-green. The flowers are 1.5–4 cm diameter, with five petals, white or yellow; in some species the flowers are bicoloured with a dark red or brown basal spot on each petal to act as a nectar guide for pollinating insects.
