Selenicereus megalanthus ist eine Pflanzenart in der Gattung Selenicereus aus der Familie der Kakteengewächse (Cactaceae).
Selenicereus megalanthus wächst hängend epiphytisch, ist reich verzweigt und erreicht Längen von bis zu 13 Metern. Die dunkelgrünen, dreikantigen Triebe sind an den Rändern leicht gewellt und nicht verkorkt. Sie sind bei Durchmessern von 1,5 bis 4 Zentimetern, 1 bis 2 Meter lang und besitzen Luftwurzeln. Aus den Areolen entspringen 1 bis 3 pfriemliche, gelblich braune und leicht gebogene Dornen, die an der Basis leicht verdickt sind und eine Länge zwischen 3 und 5 Millimetern aufweisen.
Die später stark duftenden Blüten sind bis zu 30 Zentimeter lang. Ihre Blütenhüllblätter sind auffallend breit. Die äußeren Blütenhüllblätter sind hellgelb, die inneren weiß. Das Perikarpell ist stark gehöckert und mit Schuppen, weißer Wolle und 14 bis 15 borstenartigen Dornen je Areole besetzt. Die essbaren, gelben, eiförmigen Früchte sind bis 11 Zentimeter lang und nur mit wenigen Dornen besetzt. Das Fruchtfleisch ist weiß oder rosafarben.
Selenicereus megalanthus ist in Kolumbien, Ecuador, Peru und vermutlich Bolivien in Höhenlagen von 90 bis 1800 Metern verbreitet. Die Erstbeschreibung als Cereus megalanthus wurde 1913 von Friedrich Karl Johann Vaupel veröffentlicht.[1] Reid Venable Moran stellte sie 1953 in die Gattung Selenicereus.[2] Einige Autoren stellen die Art als Hylocereus megalanthus in die Gattung Hylocereus.
Selenicereus megalanthus wird auf Grund der essbaren Früchte (die als „Pitahaya“ bzw. „Drachenfrucht“ gehandelt werden) zunehmend in Plantagen angebaut.

Selenicereus megalanthus, synonym Hylocereus megalanthus,[1] is a cactus species in the genus Selenicereus that is native to northern South America, where it is known, along with its fruit, by the name of pitahaya. The species is grown commercially for its yellow fruit, but is also an impressive ornamental climbing vine with perhaps the largest flowers of all cacti.
The yellow skinned fruit of S. megalanthus has thorns, unlike the green, red or yellow skinned dragon fruits of S. undatus, S. monacanthus and their cultivated hybrids. S. megalanthus is commonly known as "yellow dragon fruit", "yellow pitahaya", "kirin fruit", or "yellow pitaya". This name leads at times to confusion, as unrelated cultivars of other dragonfruit species can also have yellow skinned fruit. One example of a yellow dragonfruit cultivar not related to S. megalanthus is 'Australian Gold'.
Megalanthus (Greek) – large flowered. This species produces some of the largest flowers within the cactus family.
The species is native to Colombia, Costa Rica, Ecuador, Nicaragua, Panama, Peru, Trinidad and Tobago and Venezuela.[1] It is found in tropical riparian forests and is epiphytic or xerophytic.
This is an easily cultivated, fast-growing plant. It needs a compost containing plenty of humus, and sufficient moisture in summer. It should not be kept in temperatures under 8 °C (46.5 °F) in winter. It can be grown in semi-shade, but it does best in full sunlight. Extra light in the early spring stimulates budding. The plant flowers in June to October. The plant can grow to a very large size.

Hylocereus megalanthus, conocida como pitahaya, es una especie de la familia Cactaceae.
Es endémica de Colombia, Perú, Bolivia, Ecuador, Venezuela y República Dominicana. Este cactus está presente en la Reserva Biológica Jatun Sacha en Ecuador, y probablemente en la Reserva de Cuyabeno.
Es una especie común que se cultiva por su fruto y como planta ornamental, pues quizás tenga las flores más grandes de todos los cactus.
Es una planta perenne carnosa con hojas decumbentes y angulosas, armada de espinos, de color verde y con las flores de color blanco, en forma de embudo, de 32 a 38 cm de largo. El fruto es ovoide, tuberoso, espinoso, de color amarillo, con pulpa comestible de sabor agradable, ligeramente dulce, blanca grisácea, con múltiples semillas negras; interior comestible.
