Selenicereus (moon goddess and cereus). Cactaceae. Cacti with slender trailing hanging or climbing sts., more or less epiphytic: ribs several, usually low, with closely set areoles bearing small short or acicular spines: fls. large, nocturnal, fragrant; ovary and fr. covered with clusters of small spines often accompanied by long hairs.—More than 20 species are known. This genus contains a number of easily grown species which are great favorities in cult. on account of the great size and beauty of the fls. Some of the species are reported to possess medicinal properties. These plants have been referred to Cereus.

Moonlight cacti or (genus Selenicereus) is a poorly defined cactus genus found in Central America, the Caribbean and northern South America.

Clambering plants with flat to angled stems, producing aerial roots. Areoles may be with or without spines. Flowers are large and nocturnal, pollinated by moths or rarely bats. The receptacle bears small bracts, hairs and usually spines. Fruits bear numerous spines.


Read about Selenicereus in the Standard Cyclopedia of Horticulture 

Selenicereus (moon goddess and cereus). Cactaceae. Cacti with slender trailing hanging or climbing sts., more or less epiphytic: ribs several, usually low, with closely set areoles bearing small short or acicular spines: fls. large, nocturnal, fragrant; ovary and fr. covered with clusters of small spines often accompanied by long hairs.—More than 20 species are known. This genus contains a number of easily grown species which are great favorities in cult. on account of the great size and beauty of the fls. Some of the species are reported to possess medicinal properties. These plants have been referred to Cereus.

Cereus inermis, Otto. Sts. slender, climbing, 4-5-angled, deep green: areoles small, naked except on juvenile shoots and then bearing several white bristles: fls. said to be large, probably nocturnal, but not often appearing on cult. plants. This is a rather insignificant plant. Intro. from Venezuela many years ago. This is not a true Cereus, and without seeing fls. or fr. its real status can not be definitely stated. Karl Schumann, however, associated it with this group, and if of this alliance, it should be placed near S. hamatus. CH

  • S. urbanianus

Cuba, Haiti, Dominican Republic. Stems 4-5-ribbed, flowers 20–30 cm long.

  • Selenicereus hamatus - Mexico. Stems 3-4-ribbed, with knobby projections, nearly spineless. Flowers 20–25 cm long, receptacle with black hairs.
  • Selenicereus inermis - Venezuela, Colombia. Stems 2-5-ribbed, almost spineless. Flower 15 cm long, spiny, hairless. The following species are probably best treated as synonymous or subspecies of S. inermis:

  • Selenicereus wercklei - Costa Rica. Stem with 6-12 low ribs. Flower 15–16 cm long, spiny, hairless.
  • Selenicereus murrillii

Mexico. Stems only 8 mm thick, nearly spineless. Flowers 15 cm long, spiny, hairless. Closely related to S. spinulous and S. inermis (sensu lat.).

Two forms are recognized.

    • f. macdonaldiae - Honduras? Stem ribs tubercled. Flowers 30–34 cm long.
    • f. pteranthus - Mexico. Stems thick, 4-5-ribbed, spines very short. Flowers 25–30 cm long.
  • Selenicereus spinulosus - Texas, Mexico. Stems short-spined. Flowers 8–14 cm long, receptacle spiny, hairless.
  • Selenicereus vagans. Mexico. Flower 15 cm long, receptacle spiny, hairless.
  • Selenicereus nelsonii. Mexico. Flowers 20 cm long, receptacle hairless, spiny. Probably conspecific with S. vagans.
