'''Moonlight cacti''' or ([[genus]] '''''Selenicereus''''') is a poorly defined [[cactus]] [[genus]] found in [[Central America]], the [[Caribbean]] and northern [[South America]].
==Description==
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.
==Etymology==
Its generic name is derived from the old Greek moon goddess [[Selene]], referring to the nocturnal flowers. The term [[Nightblooming Cereus]] is sometimes used here, but this is also used for many night blooming cacti, including [[Epiphyllum]], [[Hylocereus]] and [[Peniocereus]].

==Summary of the species==
'''''[[Selenicereus anthonyanus]]'''''
Mexico. Stems like those of ''[[Epiphyllum anguliger]]'' but more vining and with short spines. Flowers ca. 12 cm long, 10-15 cm wide, the outer inner tepals purplish, the inner cream.
'''''Selenicereus atropilosus'''''
Mexico. Flowers 12 cm long, receptacle with black hairs. The species is close to some species in the genus ''[[Weberocereus]]''
'''''Selenicereus chrysocardium'''''
Mexico. Stems deeply lobed, ca. 28 cm wide. Flowers 32-38 cm long, 23-30 cm wide, base of receptacle very spiny. The species is close to the genus ''[[Epiphyllum]]''.
'''''[[Selenicereus grandiflorus]]'''''
Jamaica, Cuba; Guatemala, Honduras, Nicaragua. Stems many-ribbed. Flowers 18 cm long, receptacle densely woolly. Three subspecies are recognized:
<br>ssp. ''grandiflorus''
<br>ssp. ''donkelaarii'' - Mexico. Stems 1 cm thick, low-ribbed, spines short, appressed to stem. Flowers 18 cm long.
<br>ssp. ''hondurensis''
The following species are very closely related to each other and possibly better treated as synonymous [[taxa]] or subspecies.
*''Selenicereus boeckmannii'''''
Cuba, Haiti, Dominican Republic, Mexico. Flowers 24-39 cm long. Close to ''S. pteranthus''.
*''Selenicereus brevispinus''
Cuba. Spines less and 1 mm long. Flowers 25 cm long. A shortspined ''S. grandiflorus''.
*''Selenicereus coniflorus''
Mexico. Stems thick, usually with 5-6 ribs, spines to 1,5 cm long. Flowers 22-25 cm long. A long spined ''S. pteranthus'' or few ribbed ''S. grandiflorus''.
*''Selenicereus hallensis''
Colombia? Only known in cultivation and possibly a hybrid with ''S. macdonaldiae'' and some other "species".
*''Selenicereus macdonaldiae''
Honduras? Stem ribs tubercled. Flowers 30-34 cm long.
[[Image:SelenicereusUrbanianus5UME.jpg|thumb|
''Selenicereus urbanianus'' in Hatillo Palma, Dominical Republic.]]*''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 rubineus''
Mexico. Stems 4-5-ribbed. Flowers 18 cm. wide, 18-19 cm long, inner and outer inner tepals flushed ruby-red near base.
[[Image:Selenicereus_wercklei8BHAM.jpg|thumb|right|''Selenicereus wercklei'']]
*''[[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.).
''[[Selenicereus pteranthus]]''
Two forms are recognized.
<br>f. ''macdonaldiae'' - Honduras? Stem ribs tubercled. Flowers 30-34 cm long.
<br>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''.
'''''Selenicereus validus'' Michoacan, huge nocturnal flowers with bright red fruits. (Mesa Gardens 1244.5936)
