118 ALTERATION OF 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, bearimg 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 different flowers. In some 
the placenta was crowned with ovules; in others the 
ovules were replaced by a single whorl of leaflets; m 
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.”
