Cardiospermum Halicaccabum

2 or 3 internodes revolve.—

July 26 1' Plant two inches against sun in 3° 12', each in 1°. 36'

2d Plant.— 1' € do in 1°. 36

2d € do in 2° 5' [total] 3. 41'

3d Plant with sun 1' € in 1°. 48'

2d € in 1°. 59' [total] 3°. 47 average of 6 inches 1°. 46'

With internodes the peduncle revolves; but not spontaneously. — & projecting up began the tip of shoot. — Peduncle long & very thin & carrying small bunch of each buds—on opposite sides of the branch, there is a flattened hairy filament— at first parallel & projecting beyond buds, & above whole end of shoot but these soon diverge & both curve outwards so as to make more than hook — [sketch] one of these being put on to a twig in about 16th 18° became more curved.— & in about 24° took two turns round.—

[68v]

Most like in action Gloriosa Lily but with double hooks—

(Like Vine if it had 2 flowers-tendril & no other tendrils.—)

Give length if plant

(a second case) — now just like Vine — This clasped but not closely à [sketch] [illeg] peduncles elongated ß Thus ultimately incurves greatly in length & redivides

Anther [sketch] all becoming flowers not sensitive to even prolonged contact.

A miserably poor climber —

The tendrils can catch only thin twigs.—

[68b]

Uncaught to coils spontaneously into helix —

28th I tied up internode & allowed peduncle to move by self— it moved incessantly & sometimes very rapidly & to considerable distance from side to side — only occasionally making ellipse-like spires. — Seem drawn towards the light — Movement disturbed, by tying of internodes; but no doubt power of movement.—

Does not twine, (but Paullinia does.)

Rubbing several times lightly certainly produced very slight curvature in one tendril— Contracts spontaneously into flat helix —

Main peduncle does not clasp or contact spirally— which latter seems great æ

[68bv]

drawback to power of climbing. — Yet fairly good climbing plant— Looks as if to support minute flowers

Flower-tendril flattened— hairy extremity — thicker than true flower-peduncle —

When uncaught coil into Helix—

It wd. be an advantage if main peduncle had contracted spirally.

Flower peduncle which has clasped for a week or two ha is thickened & rigid & gorged appearance— At base above each fl. t. a cellular swelling. —

Augt 5th Tendril hooked to stick. in 1° 45' had curved considerably — in 2° 30' had formed a ring round stick, but did not clasp closely till 4°—5° 5° to 6° had elapsed.— A second one in nearly same times—

[sketch] ← 3 to 4 1/2 inches long →

grows considerably when straightened

—one inch long in finest specimens

Become rigid & how much stringer in caught peduncles—
