Description
Epiphyllum anguliger is an epiphytic cactus with smooth green skin and extensively branched stems. Primary stems are often woody. Secondary stems are flat and succulent, up to 30 cm long, up to 5 cm wide and deeply lobed. The lobes are rectangular or slightly rounded. The white or pale yellow flowers bloom nocturnally, exuding a strong, sweet scent. They are 8  to 20 cm long and up to 7.5 cm wide. The fruit is  up to 4 cm in diameter, ovoid and brownish, greenish or yellowish.
 
Epiphyllum are hardy to around 10°C, but require at least 15°C during the growing season, so they will do better as indoor plants. Place the pots in bright, filtered light with moderate to high humidity. To increase humidity, place the pot on a tray full of pebbles and keep them covered with water, but not letting the water come into contact with the base of the pot. Epiphyllum cacti need very well-draining growing media. They should be grown in cactus compost  or by adding some perlite to the mix.
 
Excessive stems can be cut or shortened. New shoots usually develop just behind the cut. However, be careful not to over-water after pruning as at that time the plant's water requirements will be reduced. 
Epiphyllum, after some time and when very large, can become unstable in the  pot they are in, so they may have to be changed to heavier pots, such as terracotta, or a larger container, such as like a cup. Alternatively, try using stakes and tying the stems, but this can look unsightly.
