TABLE 1.—General Table of Results of section of Distal Pinnules of
Mimosa pudica
—continued.

No. of
Experi-
ment.
Result.
11 Leaf not yet reached by the sunshine .—Very slow and partial action in the pinnules
of the distal half of the pinna, and in one on one side of the middle of the
proximal half; no further result.
12 Leaf not yet reached by the sunshine; section involving the tip of the secondary
petiole.
—Rapid, progressive action in the pinnules of the cut pinna, followed
by immediate action in the primary pulvinus; no further result.
13 Leaf and section as in No. 12 .—Immediate action of about six pairs of distal pin-
nules and of the primary pulvinus; pause; very slow, progressive action in the
other pinnules of the distal half of the cut pinna; no further result.
14 Leaf not yet reached by the sunshine; section involving tips of distal pinnules
only
.—Very slow and partial action in the pinnules of the distal third of the
cut pinna, and in some pinnules on one side at the base; no further result.
15 Leaf not yet reached by the sunshine; section involving the tip of the secondary
petiole.
—Imperfect action in all the pinnules of the cut pinna; no further
result.
16 Leaf in full sunshine; section involving tips of pinnules only .—Spreading action
in the pinnules of the cut pinna; action in the primary pulvinus; complete
action in the pinnules of the other pinnæ; no further result.
17 Leaf in full sunshine; section involving tip of secondary petiole .—Action in the
pinnules of the cut pinna; pause; action in the secondary and primary pul-
vini; complete action in the remaining pinn; action in the primary pulvi-
nus of the first leaf above.
18 Leaf and section as in No. 17 .—Spreading action in the pinnules of the cut pinna;
action in the primary pulvinus; complete action in the other pinnæ; no
further result.
19 Leaf in full sunshine; section involving pinnules only .—Spreading action in the
pinnules of the cut pinna; action in the primary pulvinus; complete action in
the remaining pinnæ; nothing more.
20 Leaf and section as in. No. 17 .—Spreading action in the pinnules of the cut pinna;
pause; action in the primary pulvinus; complete action in the other pinnæ;
no further result.
21 Leaf and section as in No. 17 .—Spreading action in the pinnules of the cut pinna;
pause; action in the primary pulvinus; complete action in the other pinnæ;
no further result.
