4. FUMAKIACE.E (Fumaria officinalis) Fumitory. 



This order contains no plant of 

 any importance. The common 

 Fumitory derives its name from 

 the supposed resemblance of the 

 odour of its flowers to smoke. 



Fumitory. 



5. BRASSICACE^; (Sinapis alba) White Mustard. 



(Nasturtium officinalis) Water Cress. 

 (Brassica oleracea) Cabbage. 



In this order are contained many 

 of the useful occupants of our 

 kitchen gardens, the Cabbage, 

 Turnip, Cauliflower, Radish, and 

 many more; they have nearly 

 all a pungent taste, and some, 

 as the Rape, yield seed pro- 

 ducing much oil. The Water- 

 cress is grown near London in 

 square pools, into which some 

 neighbouring stream is turned. 

 These pools are arranged side 

 by side, and those who gather 

 the plants lie down on a plank 

 of wood placed across. Enor- 

 mous quantities are thus sup- 

 plied to the London markets. 



Water-cress.
