Oct 12. In the anomalous Hanburya Mexicana internodes & tendrils revolve & completed  € in 1°. 45'

I shd. not have mentioned it had it not been for one anomaly.—

Whilst young Plants Young— a more rudimental branch it not far from base of t. on inner side ultim In older plants, this develops into short branch first at at right angles to main tendril— on inner side & curved down like spur to cork.— This is either pressed against or moves little way from upper young curled shoot with its immature incurved young tendril as the t. revolves; but it cannot does not go over as in Echinocystis. Whilst this rectangular branch is pressed against the shoot. The t. stands vertically up in line of axis, the apex of axis thrown to one side; & slowly t. bends down, so as to be at ∟ to axis: & ultimately depends.

Oct 14th When long branch is highly sensitive on concave tip, the top of short-branch is not more sensitive than young unformed t. — I have not seen this case before.—

When curled into hoop straightened itself in less than 50'.—

Contracts spirally when caught— The rectangular branch wd have caught apex of stem if sensitive— but it becomes sensitive only when long to begin to bend down so that the short branch is free & then its concave top assu acquires sensibility; the long t being so are same time.

Tip of long t. move with great rapidity on being touched.

Compared sensitiveness of another young t. same difference in long branch & short—

After bending down both catch own stem & stick

Oct 27th Can climb vertical stick by tendrils, not twine, I can see no difference in action of long t. & branch.—
