Fishbone Cactus
Disocactus anguliger
Epiphytic / Holiday Cacti (Schlumbergera, Rhipsalidopsis, Disocactus)Mood Meter: Go With the Flow
Also called: Ric Rac Cactus
Scientific Name History
Current accepted name: Disocactus anguliger
Previously or alternatively classified as: Epiphyllum anguligerum
How to identify it
Long flattened stems with deep alternating lobes forming a zig-zag or fishbone shape; no conventional leaves
Growing characteristics
Growth habit: trailing/arching, epiphytic. Drought tolerance: moderate.
Scientific synonym Epiphyllum anguliger is still in common horticultural use. The flattened, deeply lobed stems are normal growth and should not be interpreted as true leaves. Large fragrant flowers may appear on mature plants but aren't required for identification - the zig-zag stem shape is the primary evidence.
