Epiphyllum anguliger is a cactus species native to Mexico. The species is commonly grown as an ornamental for its beautiful, fragrant flowers in the fall.

Etymology
This species is named for its deeply toothed stems ("anguliger" = "angle bearing") which sometimes make a perfect rectangle.


History
This plant was first distributed by the Horticultural Society of London which obtained it from the collector, T. Hartweg, in 1846.

Origin and habitat
C & S Mexico (Jalisco, Nayarit, Colima, Guerrero and Matanego). Epiphytic in evergreen oak forests.

Systematics
A very variable species but rather distinct and recognition of subspecific taxa seems unnecessary. Most closely related to Epiphyllum crenatum and Epiphyllum laui.

Cultivation
An easily cultivated, fast growing epiphyte. Needs a compost containing plenty of humus and sufficient moisture in summer. Should be kept at 16-25ºC (61-77ºF), it may drop to 10-15ºC (50-59ºF) for shorter periods. Best grown in semi-shade. Flowers in late autumn or early winter.

Description
Stems profusely branched, primary stems terete at base, often woody, apical part and secondary stems flat and rather succulent, 20-30 cm long, 3-5 cm wide, deeply lobed, often to near midrib, the lobes rectangular to obtuse or rounded; areoles small nude or with 1-2 white bristles; epidermis green, smooth. Flowers 6-20 cm long, 6-7 cm wide, nocturnal, strongly sweet-scented *; pericarpel with podarium; receptacle 8-16 cm long, 4 mm thick, pale yellow, greenish or pinkish, bracteoles few, minute, linear and green, adpressed; outer tepals 10, linear to linear-lanceolate, acute, spreading or reflexed, 4-5 cm long, lemon yellow to brownish yellow; inner tepals lanceolate to ovate, acute or acuminate, white, sometimes toothed, as long as outer tepals; stamens in two rows, white, erect to subdeclinate, nearly as long as tepals; style longer than inner tepals, white; stigma lobes 8-11, linear. Fruit ovoid, brownish, greenish or yellowish, 3-4 cm thick.
