118 ALTERATION OP POSITION. 



3. In this case the corolla and calyx were distant 

 from each other ; there was no trace of stamens, but 

 the axis was continued from the centre of the corolla, 

 and ended in a leaf-bud. 



4. The calyx and corolla nearly as before, but instead 

 of stamens a whorl of little leaves was developed, in 

 the centre of which the axis was continued, bearing at 

 its tip two whorls of leaflets, alternately three and 

 three. 



5. In this case two out of the five stamens were 

 normal, the other three changed into leaves, showing 

 clearly the origin of the leaflets, in the last case, which 

 took the place of the stamens. 



6. The ovary varied in diflerent flowers. In some 

 the placenta was crowned with ovules ; in others the 

 ovules were replaced by a single whorl of leaflets ; in 

 others there was every shade of change from ordinary 

 ovules to perfect leaflets ; while in others, again, every 

 ovule was converted into a leaf with a long petiole. 



7. In these flowers shoots were developed in the 

 axils of the sepals, or on the face of the petals between 

 the point of their insertion and that of the stamens, 

 and, what is most curious, in the interior of the ovaries 

 round the foot of the placenta. 



8. Here, again, a very singular condition presented 

 itself : the calyx and corolla separated from each other, 

 the stamens partly developed, the axis continued 

 beyond the corolla, branched and bearing normal leaves 

 so as exactly to resemble an ordinary stem, while in 

 consequence of the calyx and corolla being bent down 

 to the ground, adventitious roots were developed from 

 the axis on the under side above each of them. In 

 another case, where the calyx and corolla were approxi- 

 mated, the ovary was open above, and sent out six 

 shoots from within, perfectly developed, clearly repre- 

 senting the central placenta and five axile buds, and 

 each giving out a number of adventitious roots at its 

 base."
