Intercellular spaces. After Sachs. the Pea they may be seen as very small round bodies lying in the same cells as starch grains {fig. 655). In the Lupin they are larger, and occur in conjunction with oil, but not starch. In both these cases they show no structure. In the Castor-oil seed and in that of the Brazil nut they differ from the simple forms described. The larger part of the aleurone grain is occupied by a crystalline portion, known as the crystalloid. This, like the grain itself, is proteid in character. There is present also in these grains a rounded aggregation of mineral matter, a double phosphate of calcium and magnesium, which is termed the globoid (fig. 654)..
