Aug 23d.

Bignonia unguis

The young leaves have between each pair a minute tendril, which in my plant has dropped off in all old leaves. Tendril represents lateral & terminal leaflet.— In one instance a little stick to peduncle slowly in course of 24° caused the whole foot to curl over like foot of bird in perching on branch, but did not clasp securely or well.— stick between toes caused no effect.— Rudimentary tendril?? a rare very peculiar habit?? Whole tendril a little above 4/10 of inch in length, of which peduncle rather above half.— The 3 toes equally divergent, equal in length, with tips curved at right angles & extremely sharp & hardened like hardest thorns! like falcons foot with no hind toe.—

The tendril which bent does never get straight — I now find that tendrils act well as grapnels to catch edges of leaves. They live beneath the pair of leaves. — They are developed very young so as to project beyond leaves hardly opened. — The most useless of tendrils — perhaps drop off if not become attached—

Tendrils would not help move these thorns.

No movement of leaves or internodes: no I think there is —

The 3 toes never seem to move separately; but together with peduncle they become curved downwards.

I now feel sure that touch does cause slowly curvature

Aug. 27. Young internode first moved from light, & then made a small irregular circle in 12°, & late at night moved to window.—

Aug 28th made an oval circle in 4° 20', but not quite complete then made quite a small circle.— Movements very irregular—

What small use in movement of internodes ∟ for so slight movement in tendrils Certainly are Movements in tendril

Bignonia

When branches thrown on tree certainly act like grapnels on edges of leaves
