The genus Griffinia in the Amaryllis Family (Amaryllidaceae) is endemic to Brazil. Griffinia belongs to the American clade, and it is closely related to Worsleya in the same clade. They are herbaceous perennial bulbs. The flowers are borne in an umbel at the top of the peduncle or stalk.
The amaryllid genus Griffinia is restricted to Brazil in South America, and has several species. They are all small bulbous plants whose habitat is the understory of forests. Their flowers have the same pale mauve coloration of Worsleya blooms.
