 a very long time before they strike and are fit for removal. 



CONVOLVULACE^. 



The species of this Order are very numerous, and comprise 

 many plants producing flowers of exceeding beauty, annual as

 having a faint, but most agreeable perfume, somewhat resem-

 primrose-yellow colour. 



Convolvulus. 



C. pentanthus. More commonly called Ipomoea semperflorens ;
