Flower and stemsFruit
Disocactus anguliger (syn. Epiphyllum anguliger), commonly known as the fishbone cactus or zig zag cactus, is a cactus species native to Mexico. The species is commonly grown as an ornamental for its fragrant flowers in the fall.
This species was formerly placed in the genus Epiphyllum as Epiphyllum anguliger. However, according to recent molecular research, it is actually a species of Disocactus.[2][4]
The specific name derives from the deeply toothed stems (anguliger = "angle bearing").[citation needed]
Description
This epiphytic cactus has smooth green skin and extensively branched stems. The primary stems are often woody. Secondary stems are flat and succulent, 20–30cm long, 3–5cm 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 6–20cm long and 6–7cm wide. The fruit, 3–4cm long and 2cm in diameter, are ovoid and brownish, greenish or yellowish.[5] The interior of the tasty fruit is reminiscent of kiwifruit, with green pulp and small black seeds.
Distribution and habitat
The species is endemic to Mexico, occurring as an epiphyte in evergreen forests in Oaxaca, Guerrero, Jalisco, and Michoacán and/or Nayarit. It can be found at elevations between 1,100 and 1,800 m.[1]
This plant was first distributed in Europe by the Horticultural Society of London which obtained it from the collector T. Hartweg in 1846.[6]
Cultivation
This easily cultivated, fast growing epiphyte requires a compost containing plenty of humus and sufficient moisture in summer. It should be kept at 16–25°C (61–77°F), but temperatures may drop to 10–15°C (50–59°F) for shorter periods. It is best grown in semi-shade. It flowers in late autumn or early winter.[5]
