322 THE KINDS OF PLANTS 



L. Githilgo, Scop, (or Agrostemma Githago, Linn.). Corn cockle, 

 because it is a common weed in wheat fields (wheat is known as corn in 

 Europe), its seeds not being readily separated from wheat because of 

 tlieir similar size and its seasons corresponding with those of wlieat: 

 annual, 2-.T ft., hairy: fiowers purple-red and showy, on very long stalks, 

 the petals crowned and the calyx-lobes long and leafy: leaves very narrow. 

 Europe. 



L. Coron^ria, Desv. Dusty miller. Mullein pink. Biennial or per-

 bracts at base: petals 5, clawed, sometimes with crown or scale at base of 

 blade: stamens 10: styles 3 (rarely 4 or 5) : ovary 1-celled (or incompletely 

 2-4-celled): fruit a capsule, or pod, 1-celled or 3-celled at base, dehiscent by 

 3 or G teeth at apex, many-seeded. A viscid secretion covers the calyx and 

 stems of certain species, by which creeping insects are caught, whence the

 ovate lanceolate, acute, opposite: flowers in panicles, inclined or drooping:

 on edge, pink-red, crowned. In dry soil in eastern states. 



S. Virginica, Linn. Fire pink. Perennial, 1-8 ft.: lower leaves thin,
