greater or less roughness of the stem and leaves, from its clothing of 

 rigid bristles. 



** Capsules smooth. 



3. P. du'bium. Linn. (Fig. 852.) Long smooth-headed Poppy. 

 Capsule oblong, smooth ; filaments subulate ; stem hispid, many 

 flowered ; leaves bi-pinnate, with linear remotely toothed segments.

 British Flora, ed. 4. vol. i. p. 212. Lindley, Synopsis, p. 17. 



Root tapering. Stem erect, branched and leafy, round, clothed with 

 spreading hairs. Leaves numerous, bi-pinnatifid, the radical ones with 

 channeled footstalks, the segments oblong, acute, with broad acute 

 teeth, those of the stem sessile, with narrower segments and lanceolate 

 teeth, somewhat paler on the under side, and scattered over with 

 slender spreading hairs. Flowers mostly numerous, on long peduncles, 

 clothed with pale close pressed bristles. Calyx ovate, concave, scat- 

 tered over with long spreading hairs. Petals rather large, broader than 

 long, of a light scarlet colour, creased, and mostly crenated on the 

 margin. Stamens with linear subulate filaments, and ovate two celled 

 anthers, with yellow pollen. Stigmas from six to eight rays, crenated 

 on the margin. Capsule oblong, wedge-shaped, narrow, smooth, with 

 as many ribs as there are rays of the stigma. Seeds numerous. 



Habitat. Cultivated fields ; not unfrequent. 



Annual; flowering in June and July. 



This seems to be an intermediate species between the P. argemone 

 and the following species, and the shape of the capsule is the only 

 character by which it is rendered perfectly distinct from either one or 

 the other. From P. argemone it differs in being smooth, and not 

 bristly ; and from P. Rfueas in its narrow wedge-shaped not globular 

 form. The segments of the leaves are so variable in their shape in 

 both species, as well as the close pressed or spreading hairs of the stem 

 and peduncles, as to render them characters of no dependence ; indeed, 

 it is not uncommon to find on the Continent this species almost smooth. 



4. P. Rha'as, Linn. (Fig. 853.) Common Red Poppy, or Corn Rose. 

 Capsule globose, smooth ; filaments subulate ; stem hispid, many 

 flowered ; leaves pinnate," or bi-pinnate, with oblong lanceolate cut or 

 toothed segments.

y. lobatum. (Fig. 854.) Leaves pinnated, with linear lobes, the 

 lateral ones entire, or rarely toothed, the terminal one long, linear 

 lanceolate, unequally dentato-serrated.
