FIG. 207. FIG. 203. 



FIG. 209. 



There are many other varieties 

 of polypetalous irregular corollas 

 which are described generally as 

 anomalous. Fig. 207 is a com- 

 mon form of anomalous corolla. 

 There is an interesting tribe of 

 plants known as orchids, which 

 present many anomalous forms of corolla ; Fig. 208 

 is an example, Fig. 209 being a separate flower from 

 the same plant. Anomalous flowers should be further 

 described as polypetalous or gamopetalous, for they 

 occur among both these forms.
