“ FRITILLARY (Fritillaria: from Lat. fritillus, a chess-board, so called from the chequered markings on the petals) , a genus of hardy bulbous plants of the natural order Liliaceae, containing about 50 species widely distributed in the northern hemisphere. The genus is represented in Britain by the fritillary or snake’s head, which occurs in moist meadows in the southern half of England, especially in Oxfordshire. A much larger plant is the crown imperial (F. imperialis) , a native of western Asia and well known in gardens. ”
