Bignonia picta. Aug 4th

Whole Structure & movement of internodes (a wide circle in 2° 15') & movement of tendrils (internodes being recurved) like identical with B. speciosa. —

Both t.s touched two thin stick, wound round it, so in end to be parallel to base & then loosed it.

(A third t. caught other stick, & then loosed hold & then grasped it.) (a 4th t caught & loosed stick)

One of the former t. has half would round stick &, Augt 5', is I think recurved round stick — the other still free — yet with stick close link

(Aug 5 Two new t. wound round the sticks — Aug 6th one back at ∟'; the other loosed it.

(T. remains for several hour bent at ∟' or [sketch] round thin stick— winds round & fits a post. —

[136v]

Aug 7th.

Certainly catches thin sticks pretty well, but takes much time over it but looses again & again & leaves them & comes again to the attack— The point of t. curls round stick— one has curled round post & has fitted irregularities. — Contracts spirally —

Does not search for holes. — Sp. C. draws t. off post.—

Tendrils have got power of straightening themselves —

Withdraw from post spontaneously & when corkscrew comes on is forced off.— Winds under toes but withdrew.

Does not only once twice, go into minute holes— Certainly catches thin sticks moderately well.—

Several times tried to catch Post — only twice went into crevices—Pretty good for thin sticks— does nothing with tree, sometimes wind tendrils—

Tip of t. white when young— dark purple when old & formed of larger cells.─
