Selenicereus hamatus ist eine Pflanzenart in der Gattung Selenicereus aus der Familie der Kakteengewächse (Cactaceae).
Selenicereus hamatus wächst spreizklimmend mit bis zu 4 Meter langen, drei- oder vierkantigen Trieben, die Durchmesser von bis zu 1,5 Zentimetern erreichen. Auf den Trieben sitzen unterhalb der Areolen bis zu 1 Zentimeter lange Spornen oder hakige Höcker. Die wenigen Dornen sind kurz und schwach.
Die duftenden, gelblich weißen bis weißen Blüten sind 20 bis 35 Zentimeter lang. Die Früchte sind nicht beschrieben.
Selenicereus hamatus ist im Süden Mexikos in den Bundesstaaten Oaxaca und Veracruz verbreitet. Die gültige Erstbeschreibung als Cereus hamatus wurde 1837 von Ludwig Georg Karl Pfeiffer veröffentlicht.[1] Nathaniel Lord Britton und Joseph Nelson Rose stellten sie 1909 in die Gattung Selenicereus.[2]
In der Roten Liste gefährdeter Arten der IUCN wird die Art als „Least Concern (LC)“, d. h. als nicht gefährdet geführt.[3]
Selenicereus hamatus wird gelegentlich als „lebender Zaun“ angepflanzt.

Selenicereus hamatus is a species of Cactaceae and produces one of the largest flowers in the family. It is a cultivated ornamental vine. The species is native to Mexico.
Hamatus (Latin) means "hooked", and refers to the curiously hooked stems.
Scheidweiler thought that this species originally came from Mexico, which is probably correct. Still, no evidently wild plant has been found. Although it is a quite common species, not much is known about its history.
The plant's origin in south and east Mexico. It is only known in cultivation.
S. hamatus is a distinct species, distantly related to the grandiflorus-complex. Selenicereus radicans (DC.) A. Berger seems to belong here, but it is impossible to know for sure as the original description is brief and no type seems to exist. The publication of Cereus radicans predates C. hamatus.
This is an easily cultivated, fast growing plant. It needs a compost containing plenty of humus and sufficient moisture in summer. Should not be kept under 10 °C (50 °F) in winter. It can be grown in semi-shade or in full sun. Extra light in the early spring will stimulate budding. Only mature plants produce flowers. It makes an excellent pendent plant.
Stems scandent, clambering or sprawling, branching, producing few aerial roots, very vigorous, to 5–12 m long or more, often growing 2 m or more in a season, 16–22 mm thick; ribs 4 or rarely 3-5, strong, later terete, acute; areoles small, brownish or black, remote, on the upper edges of knubby projections, these often forming obtuse, deflexed spurs about 1 cm long, internodes 4–5 cm; spines 5-6, ca 5 mm long, whitish, bristle like, 1-3 lower or central spines usually brown or black; epidermis glossy grass or light green. Flowers produced one by one over a longer period than most other species, born sparingly near tips of mature stems, 30–40 cm long, 20–30 cm in Ø,[1] nocturnal and strongly scented with an aromatic fragrance, tepals rotate, inner ones forming a broad cup; pericarpel oval, knobby, ca 4 cm thick, covered with white spines and brown or black hairs, bracteoles green with white tips.; receptacle ca 10–14 cm long, green, purplish towards the apex, ca 22 mm in Ø, its areoles with short, retuse, 1–12 mm long bracteoles, long black hairs and spines, upper bracteoles longer, the uppermost tipped purple; outer tepals 15 cm long, in 4 series, the outermost more narrow, reddish purple outside, chrome yellow inside, innermost broader, to 2 cm, acute to acuminate, greenish yellow outside, chrome yellow inside; inner tepals 12 cm, in 3 series, very broad, retuse, mucronate, white; stamens creamy white, anthers yellow; style thick, longer than the stamens, yellowish, lobes 15-18. Fruit oval, 10x8 cm, green or yellow, covered densely with yellowish spines, 2,5 cm long.
