ment is flattened, and then it frequently assumes the appearance 

 of a petal, when it is described as jpetaloid, as in the Water-Lily 

 {Nymphaa) {figs. 436, e, and 507), and in Canna and allied plants. 



Sometimes the filament is toothed, as in AUium {fig. 4:91), 

 or forked, as in Cramhe {fig. 492), or furnished -with various 

 appendages, as in the Borage {fig. 493, a), in -which case it is 

 said to be append icid ate. These appendages are evidently of the 

 same nature as the scales and other appendages, previously de- 

 scribed as occiirring on the corolla.
