72 BOTANY FOR YOUNG PEOPLE. 



which you must remember from its sharp biting 

 taste. So is the Shepherd's Purse, named from 

 the peculiar pouch-like form of the capsule, 

 This has been described as an unsightly annual 

 weed, with but little to recommend it, running 

 only too quickly over neglected gardens and 

 wastes, and has made itself a denizen of the 

 whole habitable world. The Candy Tuft, 

 Cress, and Moonwort or Honesty, as it is some- 

 times called, are in this order also. 



The second order is Siliquosae, or that with 

 a long and narrow pod. The Wall flower, the 

 most beautiful and interesting of the class, is in 

 it. We are told that the minstrels and trouba- 

 dours of former days carried a branch of this 

 flower as an emblem of an affection, that con- 

 tinues through all the vicissitudes of time, and 

 survives every misfortune. It loves to grow in 

 in the crevices of old walls, to flourish in those 

 of ruined towers, or ornament the mouldering 

 tablet, which records the names of those almost 

 forgotten by sorrowing relatives. Here is also 

 the Radish, Rocket, Mustard and Woad, an 

 article much used by dyers ; the last belonging, 

 Nuttall thinks, much more properly to the Sili- 

 culosae.
