Hippeastrum peastrum,Peru. peruvianum Meerow & Campos-Rocha features floral morphology unique among the other species of the Amaryllidaceae are a family of cosmopolitan distribu- genus occurring in the country. It has similarities tion, occurring mostly in tropical and subtropical regions with H. miniatum (Ruiz & Pav.) Herb. and H. of the world (Meerow & Snijman, 1998). In the Neo- reginae (L.) Herb. but is distinguished readily by its tropics, Hippeastrum Herb. is one of the most species-rich larger flowers, distinct coloration pattern, and trifid genera of the family (Meerow, 2009), with ca. 70 species stigma. The new species is known only from the type distributed from Mexico to Argentina. The genus has two collection by Paul C. Hutchison in 1958. It was centers of diversity: eastern Brazil and the Andes of determined as H. miniatum in error and has apparently Bolivia and Peru (Meerow & Snijman, 1998). Currently, been widely cultivated, especially in California, either Brazil and Bolivia each have ca. 35 recognized species under that name or erroneously considered a hybrid.

According to the latest existing treatment for described from Peru and later transferred to Crinum Peru, the country has 20 species of Hippeastrum (Vargas, L., is the naturalized South African species C. moorei 1984 [as Amaryllis L.]; Brako, 1993), a number of which Hook. f. are also found in Bolivia.
