Weberocereus is genus of cacti. It produces a green and white flower and is found mainly in Costa Rica and Nicaragua.[1]

A 2017 circumscription of the genus included six species:[2]

Weberocereus bradei (Britton & Rose) G.D.Rowley – Costa Rica. Stems flat, ca. 12 cm wide, margins crenate, with small spines. Flowers 5.5–7 cm long, 3.5 cm wide, white, nearly spineless.
Weberocereus frohningiorum Ralf Bauer – Costa Rica
Weberocereus imitans (Kimnach & Hutchison)Buxb. – Costa Rica. Stems flat, lobed as in Epiphyllum anguliger, with small spines. Flowers 6–7 cm long, 3–4 cm wide, base moderately spiny.
Weberocereus rosei (Kimnach) Buxb. – Ecuador. Stems flat, 4–8 cm wide, margins crenate. Flowers 5.5–7 cm long, whitish, the lower half densely spiny.
Weberocereus trichophorus H.Johnson & Kimnach – Costa Rica. Stems nearly cylindrical, spiny and densely hairy. Flower 5.5–6 cm long, pinkish.
Weberocereus tunilla (F.A.C.Weber) Britton & Rose – Costa Rica. Stems 4(-6)-angled. Flowers 6–7 cm long, pinkish.
Weberocereus tunilla subsp. biolleyi, syns. Weberocereus biolleyi, Weberocereus panamensis – Costa Rica, Nicaragua, Panama. Stems nearly cylindrical, 4–6 mm thick. Flowers 5–6 cm long, pinkish.

Some species were transferred to Selenicereus in 2017:[2]

Weberocereus alliodorus Gómez-Hin. & H.M.Hern. → Selenicereus alliodorus
Weberocereus glaber (Eichlam) G.D.Rowley → Selenicereus glaber
Weberocereus tonduzii (F.A.C.Weber) G.D.Rowley → Selenicereus tonduzii
