Pinus Austriaca

circumnutated of leaves

Fine plant. 3 ft high in large pot — observed under sky-light—

Filament with marks triangular marks affixed rather obliquely across across tips of needles

[sketch]

Needles 3 inches in length & nearly fully grown.— Needles borne on lateral branches— Branches so still stiff not tied;—

Left-Hand needle. Tracing I apex of leaf 10 inches from vertical glass observed observed from 9° a.m. July 31' to 2° P.m Aug 1'

Right Hand leaf Tracing II observed during same period, apex of leaf 8 inches from glass. — Both no doubt circumnutated, though on very small scale.—

(P. Austriaca– two leaves 3 inches in length long not quite nearly fully grown, borne on a [illeg] branch of a young tree 3 ft in high growing in a large pot, was observed during 29 hrs on July 31', in the same manner as the leaves of those of the last species. Both these leaves certainly circumnutated on a small scale, making within the above period 2 two or 2 two & a half irregular & very small ellipses.
