larger corollas cream-color. — A southern species, bvxt occurring north of

Jussieu, Genera, 236 (1789). Papavera, Adanson, Fam. ii. 425 (1763). 



Herbs {Dendromecon shrubby) with a colored or milky narcotic juice, 

 commonly glaucous foliage, and mostly solitary showy 4-merous or 

 6-merous flowers. Sepals 1, 2 or 3, caducous. Petals 4 — 6, crumpled in 

 the bud. Stamens 6 — ao , usually hypogynous (in Eschsclilotzia mostly 

 epipetalous); anthers innate. Pistil compound and the ovary becoming 

 a capsule, or the carpels nearly distinct, maturing as almost follicular 

 pods. Seeds oo ; albumen fleshy or oily; embryo minute, straight. — A 

 not very large order, but of importance as yielding the opium of com- 

 merce; many of the species valued in cultivation as 'ornamental plants. 



1, PAP AVER, Plinii (Poppy). Glaucescent more or less hispid herbs 

 (ours all annvial), with milky juice, alternate lobed or dissected leaves, 

 solitary long-peduncled flowers nodding in the bud. Sepals 2. Petals 4. 

 Ovary with 4 or more intruded placentae which partially divide the 

 interior of the obovoid or subglobose capsule; this opening by short 

 roundish or triangular apertures near the summit between the parietal 

 ribs: stigma 4 — 8-lobed, sessile and the lobes radiating over the summit 

 of the ovary and capsule, or raised on a short style and the lobes capitate- 

 recurved. Soeds oc' , small, scrobiculate or reticulate.
