In some of the specimens exam-ined, the whole of the cortex seemed filled with starch granules,while others failed to show its presence so profusely. The grains. Fig. S, starch grains found in the root of Soianum Carolinense*; magnifiedabout 40f) diameters. show distinct stratification lines. In shap>e some were oblong, someellipsoidal and others in clusters of two, three or four, the oval oroblong-ovate being, however, the most common form. The hilumis distinct, eccentric, and usually presents a fissured appearance. 84 Solannm Carolinense. {^Y^J>r^Iiy^m^ Some of the grains were bi-nucleated and others possessed a pecu-liar, contorted shape. The starch grains resemble somewhat inshape those of another plant of the same genus, Solanum tuberosum,the potato. Scattered irregularly through the cortex of the root,and less profusely in the stem, are secretion cells containing a pecu-liar, mucilaginous-like matter. On treating these cells with potas-sium hydrate test solution they were rendered clear, and their con-tents now shown to be a white, granular or crystalline substance, by dissolving in warm hydrochloric acid, without-ef
