ORDER 4. PAP AVERAGES 



On the left above is represented 

 an opening bud of Eschscholtzia. 



I The cap-like calyx has been split at 



the bottom and shoved upward by 

 the expanding petals. Next to this 

 bud is an open flower of Meconopsis and one of its nodding buds. Behind the flower, 

 and projecting above it to the right, is a stem from which the petals have just fallen. 

 The slender filaments bending to one side, as they often do, show the curious pistil 

 which in time becomes the pretty fluted capsule seen below. To the right of the Meco- 

 nopsis pod is the three-sided capsule of Platystigma lineare. The stem should have a 

 few hairs upon it. The two flowers with hairy stems, the nodding buds below, and the 

 rough seed pod above, belong to Platystemon. Observe the three caducous sepals, just 

 ready to drop from the opening bud. The smooth plant on the right is Platystigma 

 Californicum. If you choose you may call this the Smooth Platystigma, and the other 

 species, with the triangular pod, Hairy Platystigma. The exceedingly prickly Bristly 

 Argemone is represented 011 the right, below, by a bud and a couple of bracts. A pistil 

 with its white prickles is imperfectly shown against one of the bracts. 

 The Order Papaveraceas is characterized by flowers with 2 or 3 caducous sepals,
