Hippeastrinae is a subtribe of plants classified under the tribe Hippeastreae. It belongs to the subfamily Amaryllidoideae of the Amaryllis family (Amaryllidaceae).
Terrestrial bulbous perennial herbaceous plants, although three species of Hippeastrum are epiphytic. The leaf shape is linear, lorate, or lanceolate (Eithea has oblanceolate-petioled leaves). The leaf growth pattern is annual or persistent, and often histeranthous. Their texture is firm, and they are moderately canaliculated internally. The scape is hollow and the spathe has two bracts which may be fused or free.
The inflorescence may have between one and thirteen flowers. The flowers, which may be sessile or pedicellate have a perigone that is actinomorphic to highly zygomorphic, and is tubular, campanulate or infundibulorm in shape. The tepal-tube may vary from obsolete to being more than half the length of the perigone. When a paraperigone is present it consists of basal appendages that are diminutive, membranous, bristle-like, and forming a fimbriate-lacerate or callose ring, partly adnate to the throat of the perigone, surrounding the fascicle of the stamen.
