Papaver bracteatum Lindley, which some authors have included in P . orientale , is similar but more robust, with buds erect, sepals subtended by 3-5 sepaloid and 2 foliaceous bracts, flowers to 20 cm diam., deep red petals with dark basal spot, and capsules to 4 cm. It is widely cultivated and may occasionally escape but apparently does not become naturalized.
