Corolla of 4 petals, joined in two pairs at the base of the stamens, the pairs free, broad-ovate, induplicate-valvate, concave and enclosing the stamens, closely so and raised on a common 'stalk' at maturity in N. johnsonii. Stamens 2, each enclosed in the concave pair of petals. Ovary 2-locular with 2 ovules per loculus; style short; stigma 2-lobed.
