Epiphyllum oxypetalum - Orchid Cactus

Orcid Cactus is a cactus native to Central Mexico to Nicaragua. It blooms at night, since the flowers are predominantly pollinated by bats and large moths. Pure white flowers, the size of a dinner plate, open as soon as the sun goes down and stay open all night, closing in the morning. Sepaloids are often recurved, pale green or pinkish red, linear to inverted-lanceshaped. Petaloids white, inverted-lanceshaped to obovate, 7-10 × 3-4.5 cm. Filaments white, 2.5-5 mm; anthers cream, 3-3.5 mm. Style white, 20-22 cm; stigmas 15-20, cream, narrowly linear, 1.6-1.8 mm. It is a shrub growing on trees, freely branched, 2-6 m tall, with aerial roots. Old stems and basal extension shoots round, to 2 m or more, woody; branches numerous, dark green, laterally flattened, leaflike, lanceshaped to oblong-lanceshaped, 15-100 × 5-12 cm, hairless, base wedge-shaped, narrowed, or stalked, margin wavy to deeply rounded toothed, tip pointed to tapering; midrib 2-6 mm wide, stout. Fruit is rare, purplish red, oblong, about 16 x 5.7 cm. Seed 2-2.5 × about 1.5 mm. Flowering: June-October.
