==Description== The stems are broad and flat, 1–5 cm broad, 3–5 mm thick, usually with lobed edges. The flowers themselves are large, with diameters ranging from 8 to 16 cm, white through red, with numerous petals. These flowers have notably short, nocturnal antheses, blooming only at night, and wilting at dawn. The fruit is edible, very similar to the pitaya fruit from the closely related genus Hylocereus, though not so large, being only 3–4 cm long.
