Potato Starch, from tubers of Solatium tuberosum (family Solanacece), is distinguishable from wheat starch by the naked eye. The grains are so large that they are recognized as such even without the aid of a lens. The paste made from it is not so stiff nor so viscid as that made from wheat starch; it has also an unpleasant smell. The grains are mostly, but not always, simple, large and oval, and the layers are very distinct (Fig. 348). The nucleus is near the narrow end; the eccentricity varies from one-fourth to one-sixth. 249. Rice Starch, from Oryza sativa (family Gra- minecE'), often has a yellowish color, but sometimes (the finest) is dazzling white. It is often bleached with chlo- rine compounds. It appears to the unaided eye like wheat starch ; but with the simple lens no grains are visible. The grains are (1) single, and of the same size as the partial grains; and (2) compound, which are oval and consist of 2-100 parts. Instead of a nucleus, they have Fig, 348.
