While Yaozhou bowls of this general pattern are well known, the inclusion of the sagittaria leaf in the design on the present bowl is very unusual. A carved Yaozhou bowl of slightly larger size (22.5 cm.), but also incorporating a sagittaria leaf into the design, is in the Tokyo National Museum, and illustrated in Oriental Ceramics, The World's Great Collections, vol. 1, Tokyo, 1982, no. 71.
