TABLE X.—Results of Application of Heat to the axes of Mimosa pudica
—continued.
No. of Experi- ment. |
Result. |
56 | Application as above, midway between inferior and superior leaves. —Slight dis- colouration; action in four distal leaves; no action below. |
57 | Application as above, close to the inferior leaf and about 1.5 inches from the next superior one. —No exudation; successive centrifugal action in all eight distal leaves; no action below, although the inferior leaf was readily responsive. |
58 | Application as in No. 57. —No exudation; action in all seven distal leaves; no action below; inferior leaf readily responsive. |
59 | Application as in No. 58. —Centrifugal action of all distal leaves; action in two leaves below; discolouration; no visible exudation. |
60 | Application as in No. 59, close to the inferior leaf and about 1 inch from the su- perior one. —No discolouration; no exudation; action in four leaves above, consisting of partial action of the primary pulvini, and slight action of pinnules; no action below; inferior leaf readily responsive to direct influences. |
61 | Application as in previous experiments near the inferior and distant from the superior leaf. —Action in the inferior leaf, and spreading centrifugal action in all the distal leaves; discolouration, and visible exudation of a large drop of fluid. |
62 | Application as in No. 61, close to the inferior leaf and about 1.5 inches from the superior one. —Discolouration; no exudation; progressive, slow, centrifugal action in all distal leaves; no action below. |
63 | Application in No. 62, about 0.75 inches from leaf next below and 4 inches from leaf next above. —Discolouration, and slight exudation; centrifugal action in all eleven distal leaves; no action below. |
64 | Application as in No. 63, about 0.5 inches from the inferior and 1.75 inches from the superior leaf. —Slight discolouration; no visible exudation; action in three first leaves above; no action below. |
65 | Application as in No. 64, on a strong, hard axis, close to an inferior leaf and far from the distal one. —No visible discolouration or escape of fluid; action in several leaves above; no action below. |
66 | Application as in No. 65, about 0.5 inches from next leaf below and 13 inches from leaf next above. —At one and a half minutes from the cessation of the appli- cation the leaf below and the two first leaves above acted; at two minutes the third leaf above the site of application acted; at 2.25 minutes the fourth and terminal leaf acted. The axis was a hard and dry one, and the application caused discolouration, but no exudation. |
