5 rOLYANDRIA. MONOGYNIA. 



flowering' in March and April, v. v. A smaller specie* 

 than the following-, the whole plant somewhat glaucous, 

 scattered with diaphanous hairs and the peduncles often 

 proliferous. 



2. * petiolatinn. Leaves ample, smooth, upon long peti- 

 oles, pinnatiBdl}' lobed, lobes 5 to 7, with larg-e ang-ular 

 indentures. Mab. In very shady woods on the banks 

 of the Ohio, abundant; flowering from the latter end of 

 May to July. Obs. Koot perennial. Stem subquadran- 

 gular 2-leaved, rarely 3; 12 to IS inches high. Petioles 

 often nearly the length of the leaves. Leaves large, 

 about 8 inches long and 6 wide; smooth and glaucous 

 beneath; veins on the under side subpilose, sinualely pin- 

 natifid, 5 to 7 lobed, lobes large, angularly and incisel}' 

 tootlied, terminal lobe partly confluent, often somewhat 

 trifid. Peduncles aggregated, about 3 inches long, pilose, 

 arising from the centre of the stem, subcymose, cyme 

 closely sessile. Calix pilose, abruptly acuminate, 2-leav- 

 ed. Petals 4, roundish, cuneate towards the base, deep 

 yellow, nearly as large as those of Glauduvi lutenm. 

 Style more than half the length of the germ, (about 2 

 lines), yellow, stigma capitate, 4-lobed. Capsule elliptic, 

 or oblong-elliptic, turgid, and densely setose, containing- 

 many seeds, valves 4, thickish, bursting and becomin,^ 

 revolute. Receptacle similar to that of Argemone, ap- 

 plied to the margin of the valves and connected with the 

 persistent style. Seeds excavately punctate, and longi- 

 tudinally crested at the hilum, but not striated, brown 

 and smooth; albumen of the seed white and oily, envelop- 

 ing the minute embryon. — These 2 species possess no 

 affinity which I can perceive to Sanguinaria more than to 

 tiie rest of the order, but they are distinctly allied to 

 Chelidonium. 



A genus hitherto peculiar to the western parts of the 

 United States. Papaver camhricuin of Europe appears, 

 Iiowever, to belong to this genus, with which it agreea 

 almost exactly in habit, but the stem is branched, the 

 stigma obsoletely 5-lobed, and the capsule smooth, but is 

 it not valvular?

 ma sessile, capitate, lobed. Capsule superior, 

 with 3 to 6 angles, semi valvular, valves 3 to 6.
