COREOPSIS. 



The earth should be kept moderately moist, and the water 

 given in small quantities at one time. The plants, being

This genus furnishes to the materia medica two of its 

 most powerful drugs : scammony, from a species growing

 Mexico. They are obtained from the roots of the plants.

 to the sunshine :

" Like flow'rsj which shrinking from the chilly night, 

 Droop and shut up ; but with fair morning's touch 

 Rise on their stems, all open and upright."
