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

supernumerary corolla with the petal-like segments attached to its 
outer surface (reduced). 
corolla produced by duplication, and adherent to the 
inner surface of this latter were five stamens. So far 
there was nothing very peculiar; it remains to say, 
however, that on the outer surface of the second 
corolla were five petal-like lobes closely adherent to it 
below, but partially detached above. The colour of 
the adventitious segments was paler on the outside 
than on the inner surface, as in the corolla itself. The 
position of the several parts was such that they were 
opposite one to the other ; hence, while the lobes of the 
mner corolla were opposite to those of the outer one, 
the intermediate petalodes were opposite to both; thus:
