Calochorti Spec. Div., Plate 75

This botanical illustration from A. C. Van Eeden's *Flora of Haarlem* depicts five varieties of Calochortus (mariposa lily) rendered by Dutch artist Arentine H. Arendsen. Each numbered specimen displays the characteristic cup-shaped flowers in white, yellow, pink, and deep purple, with detailed attention to stamens, markings, and buds. The spare gray background and linear green stems emphasize the flowers' structural geometry. Hand-colored chromolithography achieves subtle gradations across petals and precise rendering of botanical detail—a standard format for 19th-century regional flora surveys that combined scientific documentation with aesthetic presentation.
