June 3. 1864 Lophospermum scandens (purpureum

Young plants with long internodes put sticks to 2, seized them with leaf-stalks which soon swelled considerably.

The shoot bent in opposite direction so that stick was seized as in pincers. The bending of the shoot was in opposite directions in the 2 plants. I never saw such an appearance in a shoot, for it was not like twining, Hence I rubbed several shoots 6 or 8 times. In a few hours afterwards they were all bent that way. I then tried more carefully with 2 other plants & rubbed one parallel to 2 leaves & one at right angles; in 2° one was considerably bent & in 3° the other.

In 3° or 4° afterwards both were straight again, Next day I rubbed both at right angles to former place, & both were again bent at about same time & straight again

These were rubbed about middle & high up. Those that caught the stick naturally pressed the shoot at its very base. Hence whole internode on all sides is very sensitive.

June 9th Rubbed 6 or 7 rather lightly 2 petioles on opposite sides; in 1° 15' a trace of movement in 1° 45' plainly askew & in 4° 15' still more plain, & came straight again during night.— The internodes did not in my room move when rubbed!! too young??

June 12th. Rubbed 4 very young growing stems in Hothouse & 1 in Greenhouse & in 2° they were all 5 well bent after a dozen rubs,— but some older stems did not move. —

Tail of worsted caused movement in leaf-stalk

average 3° 15'
