This nour- ishment in the embryo of the Red-Maple seed was a few weeks before in the trunk of the mother tree, as a sweet sap, that is, as Maple-sugar. 37. Variations of the Plan of Growth. In the Moming-Glory, after the pair of seed-leaves, only one leaf is found upon each joint of stem (see Fig. 23 and 4). In the Maple there is a pair of leaves to every joint of stem, as long as it grows. In tlie Moming-Glory the food in the seed, for the growth to begin with, was stored up -outside of the embryo ; in the Maple it was stored up in it, that is, in its seed-leaves. The plan is evidently the same in both; but there are diifer*.
