cited by Reinsch/ where two female flowers of Salias 

 cinerea were so united with a male one ' as to produce 

 an hermaphrodite blossom. 



It follows, from what has been said, that the number 

 of parts that are met with in these fused flowers varies 

 according to the number of blossoms and of the organs 

 which have been suppressed. Comparatively rarely do 

 we find all the organs present ; but when two flowers 

 are united together we find every possible variety 

 between the number of parts naturally belonging to 

 the two flowers and that belonging to a single one. 

 Sometimes instances are met with wherein the calyx 

 does not present the normal number of parts, while the 

 other parts of the flower are in excess. I have seen in 

 a Calceolaria a single calyx, with the ordinary number 

 of sepals, enclosing two corollas, adherent simply by 

 their upper lips, and containing stamens and pistils in 

 the usual way. In this instance, then, the sepals of 

 one flower must have been suppressed, while no such 

 suppression took place in the other parts of the flower. 



Professor Charles Morren paid special attention to 

 the various methods in which the flowers of Calceolarias 

 may become fused, and to the complications that ensue 

 from the suppression of some 

 parts, the complete amalgamation 

 of others, &c. Referring the reader 

 tQ the Belgian savant's papers for 

 the full details of the changes ob- 

 served, it is only necessary to 

 allude to a few of the most salient 

 features. 



Sometimes the upper lips of two 

 flowers are fused into one, the two 

 lower remaining distinct. In other ^iq. 18. Svnanthic 



cases, the upper lip disappears flowersof Calceolaria in
