The better known of the two, Amaryllis belladonna, is a native of South Africa, particularly the rocky southwest region near the Cape. For many years there was confusion amongst botanists over the generic names Amaryllis and Hippeastrum, one result of which is that the common name "amaryllis" is mainly used for cultivars of the genus Hippeastrum, widely sold in the winter months for their ability to bloom indoors. Plants of the genus Amaryllis are known as belladonna lily, naked lady, or amarillo. [more]

However, both the APG system and APG II system do recognize such a family and place it in the order Liliales, and the clade monocots. It differs from the closely related Smilacaceae only in that Rhipogonaceae is a twining vine that lacks tendrils, its seeds contain starch, the flowers are hermaphroditic, and the five sided anthers are longer than the filaments.
