9. PAP AVER/, Tourn. Poppy. (Latin name of Poppy, of obscure deri- 

 vation.) — Annual or perennial herbs; with narcotic juice milky, rarely turning

 peduncle, drooping in bud except in the large-flowered perennial species. — Inst.

* Annuals of the Old World, sparingly and locally adventive, not enough so to count as 

 constituents of our flora. 



P. soMNfFERUM, L. (Garden or Opium Poppy.) Glaucous, glabrous, or peduncles liispid: 

 leaves clasping, oblong, undulate, dentate or incised : corolla large, purple to white : capsule 

 globular, with numerous septiform placenta;. — Escaped from gardens in some places at the 

 East. 



P. RntiiAS, L. (Corn Poppy of Eu.) Sparsely hispid : leaves deeply pinnatifid and lobes 

 incisely dentate or again pinnatifid : corolla 2 to 4 inches in diameter, scarlet, often with dark 

 centre: capsule globular, glabrous: stigmatic rays and placentae 8 to 12. — Rare in ballast 

 grounds : found occasionally in grain-fields. 



P. DUBiDM, L. Smaller and leaves more cut into narrower lobes than in the last : bristles 

 on peduncles appressed: corolla paler red: capsule oblong, narrowed at base, glabrous:

* * Annual, indigenous. 



P.* Califdrnicum, Gray.^ Very much like P. duhimn, but hairs scanty, much finer: 

 petals saffron or more red, with lemon-colored or greenish eye toward the base : capsule 

 (about half inch long) clavate-turbinate, 6-11-merous; dehiscing by dentiform subquadrate 

 valves a line long and wide, disclosing the placentas. — Proc. Am. Acad. xxii. 313; Brau-

1 In the light of Mi.ss Eastwood's notes (Zoe, iv. 4), A. HTSProA, Gray, differs strikingly in the 

 field from tlie typical A. platyceras, the former being much more densely setose, witli generally 

 much finer spines or bri.stles, more sessile heads, paler foliage, and less deeply pitted seeds. It is 

 doubted, however, whether these differences are more than varietal, as apparent intermediates occur.
