The amaryllid genus Worsleya is restricted to Brazil in South America, and has but a single species, Worsleya rayneri, the so-called "Blue Amaryllis." Although the common name refers to it is an amaryllis, it's closest relatives are small plants in the genus Griffinia. Worsleya can become quite large in its native habitat.
