A miserable parasite often troublesome 

 Dodder m gardens, but found in low, damp, shady 



Cuscuta situations. It climbs high upon other 



Gronovii plants by twining closely about their 



Dull white stalks and exhausting their juices through 

 a thousand tiny suckers. Its threadlike, 

 twisting stem varies in color from dull yellow to dull 

 orange, it is crowded with bunches of tiny dull white 

 bell-shaped flowers having five lobes. The calyx is 

 greenish white. All the dodders start at first from the 

 ground, but finally securing a convenient plant upon 

 which to climb, the root in the earth dies and they be- 

 come parasitic. Common everywhere.
