Corydalis claviculata. Sept. 27'

Plant 6 or 8 inches high— Leaves with 3 terminal leaflets very small & petioles regularly clasped stick.— Mohl says outer leaves developed alone into tendrils.— Ask Oliver to look— —

The above small leaflets show intermediate state. — (Interesting if proved that only certain leaves of adlumia were leaf-climbers & at tips alone. —) Above good, excellent gradation.— In earlier leaves, terminal leaflets are longer,— lower lateral petioles very slightly & slowly sensitive—, except basi-lateral which are not.

Petiole if little 3 terminal leaflets far most sensitive.

Sept. 30 A leaf with 3 little terminal leaflets each only 1/10' of inch in length of lamina, was in continual movement & swept fine large

[1v]

N.B No leaf-climber contracts spirally after catching.

Oct 27 At least with young leaves, the terminal leaflets grow a little after clasping a stick. Apparently as plant grows older terminal leaflets take more character of tendrils: ie. leaflets generally smaller
