About hedges, the borders of fields, and in ground newly cleared, 

 on a clay soil. 



Annual. June, July. 



Root tapering, and, like the whole plant, abounding with a some- 

 what milky, extremely bitter, juice, //eri bright shining green, 

 beset with rigid very pungent bristles, each springing from a 

 white tubercle or wart. Stem round, furrowed, solid, branched, 

 leafy, 2 or 3 feet high. Lower leaves lanceolate ; upper heart- 

 shaped, clasping the stem. Fl. an inch broad, of a bright golden 

 yellow. Outer calyx of 5 broad, heart-shaped, loosely spreading 

 leaves, or scales, as long as the inner one, and fringed with 

 prickles. Seeds curiously wrinkled or furrowed transversely, a 

 more striking and important character of the genus than the in- 

 sertion of their feathery doicn, which in this species is elevated 

 on a stalk about its own length.

 Haller. 



A nearly smooth variety of the plant before us is represented in 

 Hermann's Paradisus, p. 185.
