The process concludbd. Soon the radicle has extended, and, pale in color, has hidden itself ini the bosom of the dark, damp earth. Now the cotyledons, unfolding and grad- ually freed from the seed coats, display themselves at length as a pair of green leaves. Lastly the plumule appears in open air, a green bud, already showing a lengthening base, its first internode, and soon a pair of regular leaves, lobed as all maple leaves. The embryo is now an embryo no longer, but a grow- ing plant descending by its lower axis, ascending and, expanding by its upper. 613. 'What beoomes of the cotyledons. The germination of the tulip-tree, oak, pea, squash, and other Dicotyledons maybe watched with equal advantage, and the chief difference observed among them will be in the disposal of the cotyledons. In general, these arise with the ascending axis, jis in the maple and bean, and act as the first pair of leaves; but some- times, when they are very thick, as in the pea, ^ , u . wv .. ..1. 1 buok-eye, oak (6â9); they remain as first Germination of Wheat; o, the grain , , .o ^, â ,o ,â ,o^ .,, , containing the cotyledon; c, plumulej r, Plaoed with the ooUum (§ 118), neither ascend- radicle; «, rootlets (adventitious).' ingnor.
