Hippeastrum reticulatum, the netted-veined amaryllis, is a flowering perennial herbaceous bulbous plant, in the family Amaryllidaceae, native to South America.

[1] Originally described by L'Héritier as petalis venosis transversal distincta,[4] a reference to the defining characteristic of the species with an unusual and exquisite venation of the petals, darker than the purple to pink background color.

The seeds are unusual for Hippeastrum in being orange-red, round, turgid and fleshy rather than black and paper like.

[12] The specific epithet reticulatum is Latin for "netted", referring to the venation of the petals.

[5] Hippeastrum reticulatum blooms in late summer to autumn, with an active growing season of autumn to early winter, and requires a semi-dormant period of 4–6 weeks during late winter and early spring.
