ternatmg with them. The ovary was not twisted, and only slightly 

 bent to one side, so that the flower faced more nearly upward than 

 m the ordmary form. The column, as usual, consisted of united 

 stamens and pistils, but it was much less bent to one side, and the 

 union ot parts was not nearly so complete. There were three dis- 

 tinct anthers mstead of two, alternating with the lobes of the dis- 

 tinctly three-lobed stigma. Instead of one large, dilated, triangular, 

 fleshy body, apparently occupying the place of the third stamen in 

 the ordmary form, and heretofore supposed, in fact, to be homologous 

 with the third stamen, there were two of these bodies alternating with , 

 the petals and evidently belonging to a distinct whorl. They may 

 really be the homologues of stamens, but, if so, the plan of the flower 

 contemplates two distinct sets of stamens; or we may regard them as 

 petals belonging to an inner whorl that alternates with the first.
