The Square Mariposa Lily is a member of the lily family (family Liliaceae). Lilies are mostly perennial herbs from rhizomes, bulbs, or corms. The family is extremely complex and botanists estimate 250 genera and 4,000-6,000 species. Many, including tulips and day lilies, are handsome ornamentals. Asparagus, Sarsaparilla, onions, and the medicinally useful Aloe are from the family. A few species are poisonous.
