Stems somewhat woody, branching, the branches terete at base, flattened and thin above, 
sometimes 5 cm. broad, green; margin of branches coarsely crenate; flowers diurnal, the tube 2 
cm. long; inner perianth-segments oblong, more or less spreading; filaments and style elongated, 
slender; stigma-lobes 5 to 7. 
Type locality: Mexico. 
Distribution: Mexico or Colombia, but 
known only from cultivated plants. 
The distribution of this species is assigned 
to Mexico, but both Edwards and Sims state 
definitely that it was first observed by Hum- 
boldt and Bonpland near the village of Tur- 
baco, which is a few leagues south of Carta- 
gena, Colombia. From seeds collected at that 
time, plants were grown in the garden of La 
Malmaison; one of these flowered in 1811 and 
was described and illustrated as Cactus spect- 
osus in 1813. 
This is one of the oldest known species 
of cacti; it was figured by Hernandez in 1651 
and by Plukenet in 1691. It has long been in 
cultivation, perhaps in prehistoric times. 
It is often hybridized with other species. 
The following hybrids with it are given: 
Phyllocactus phyllanthoides albiflorus, striatus, 
striatus multiflorus. 
Salm-Dyck (Hort. Dyck. 65. 1834) lists 
four varieties as follows: Cereus phyllanthoides 
curtisii, C. phyllanthoides guillardieri, C. phyl- 
lanthoides jenkinsonii, and C. phyllanthoides 
vandesii. Pfeiffer (Enum. Cact. 124. 1837) 
also mentions Cereus phyllanthoides albiflorus.. “a produced 
Epiphyllum vandesti Don (Gen. Hist. D'chl. Pl. 3: 170. 1834) is a hybrid produce 
by placing the pollen of Epiphyllum phyllanthoides on the stigmas of Heliocereus elegantis- 
Simus.
