June 11' to morning of 13th 1878.

Oxalis Valdiviana.

circumnutation of terminal leaflet

Leaves like those of O. acetosella— petiole very long secured to stick

Close under 3 leaflets. Observed under skylight — [sketch] apex 4 3/8 from vertical glass. Temp. 15 1/2 to 16 1/2 to C.

Right Hand leaf young, but appearing full-grown. See tracings —

Interesting case, on 11th & 12 of June the leaf circumnutated from abo 11º to about 5º P.m, when the great fall commenced, so that by 9º hung perpendicularly down; must rise up horizontally very early in morning, for by 6º 50' was falling, afterwards to rise again. — If we regard the tracing in middle of day case like the circumnutation of any other ordinary non-sleeping leaf, & the sudden fall & rise late in evening & very early in morning is sole difference.

Another & older leaf was also observed, apex 4 3/4 inch from vertical glass see other Tracing— but this is not accurate for tracing was accidentally being blurred— bud leaflet circumnutate slightly but in very complicated manner from 8º 45 a.m. to about 3º P.m─ On noon morning of 13th fell from 6º 50' a.m to 8º. 15' a.m. just like the younger right-hand leaf.—
