Selenicereus anthonyanus is a cactus species native to southern Mexico. Epiphytic in rainforests. 700–800 m alt. Seems to be of rare occurrence. It is grown as an ornamental because of its beautiful nocturnal flowers and unusual stems.

Flowers 10–12 cm long, (10-) 14-17 (-20) cm in Ø, nocturnal, very fragrant; pericarpel 15–20 mm long, green, bracteoles 1–2 mm long, olive green, their axils with dirty gray wool, grayish-brown bristles and stout, pale brown spines, 1–3 mm long; receptacle 3–4 cm long, 1–5 cm in Ø, terete, bracteoles 3–6 mm long, ovate-lanceolate, the lowermost with wool and bristles, the upper naked, the uppermost 8–10 mm long, madder purple; outer tepals outermost 1–2 cm long, similar to bracteoles, inner 6 cm long, spreading-recurved, lanceolate, madder purple; intermediate tepals 5, lanceolate, acute; inner tepals ca 10, 6 cm, lanceolate-acute, erect-spreading, cream, outermost cream with lower margins madder purple; stamens short, 15 mm long, yellowish; style 6,5–7 cm long, 6mm thick above the throat, in the throat abruptly contracted to 4mm thick, cream, stigma lobes 12-14, lanceolate, 16–18 mm long.
