Papaver Californicum GT8ij.^=P..Lemmoni Greene. 



This plant, as Dr. Gray notes in his description, very 

 strongly resembles our common 3Ieconopsis. In abundant 

 specimens of both, brought from the vicinity of Santa Bar- 

 bara by Mr. Brandegee, the resemblance is even greater 

 than was supposed, for the flowers prove to be hardly dis- 

 tinguishable in color, and some of the specimens of Mecon- 

 opsis brought from Santa Cruz Island are hairy. 



If there were a plant "exactly intermediate in its stig- 

 matic structure" between P. Californicimi a.nd 3feconopsis 

 heterophylla which otherwise bear such strong resemblance, 

 all the forms would probably go as Papaver heterophyllum 

 (Benth.), but in fact the specimen sent us by Mr. Spence 

 from the original locality has precisely the " conical apicu- 

 lation" (very common in poppies) which Avas supposed to jus- 

 tify P. Lemmoni. It varies, of course, in height, and the 

 capsule in breadth, in different specimens or on the same 

 plant.

 Papaver heterophyUum Greene. 



There is a structural difference between this plant and 

 Papaver Californicum, which appears to have escaped no- 

 tice. The stout external ribs of the capsule in Meconopsis 

 are evidently continuous with the nngles of the concave 

 disc. In Papaver they are immersed in the capsular walls, 

 and unite with the conical disc beneath the angles.

 flexile Greene. 



The capsule in dehiscence separates at first from the 

 base, afterward breaking away near the top from the firm, 

 persistent placental ribs. Margins of the leaves membran- 

 aceous, usually when mature becoming rough by fissure. 



D. flexile is a very luxuriant form; the membranous mar- 

 gin of the leaves usually entire, but not revolute. The 

 thorn-like axillary buds are the same in all the forms.
