already referred to at p. 446. In some flowers of Datura 

 fastuosa a similar series of excrescences was observed ; 

 the calyx and the corolla were normal within the latter, 

 intervening between it and the stamens was a second

 inner corolla were opposite to those of the outer one, 

 the intermediate petalodes were opposite to both ; thus :
