| In Mimosa, the responsive movement is brought about by a sudden diminution of turgor in the pulvinus. |
| Leaves move by means of turgor pressure changes at the pulvinus at the base of each lamina. |
| I have already described the effects of variation of turgor on the motile pulvinus of Mimosa. |
| This is accentuated by the expansion of the upper half of the pulvinus which is normally in a state of compression. |
| With the exception of petiole length, pulvinus length and stipule length, the other leaf characteristics overlap between the two species. |
| The movements of leaves of sensitive plants are caused by variation of turgor in the pulvinus induced by stimulus. |
