There are approximately 14 species of Pancratium, distributed on the seacoasts of southern Europe, western and southern Asia, and northern and tropical Africa. The USSR has one species, P. maritimum, which grows along the sandy shores of the Black Sea. P. maritimum and P. illyricum are occasionally cultivated as ornamentals. Species of the closely related genus Hymenocallis are sometimes classified among the Pancratium.
