The process concluded. Soon the radicle has extended, and, pale iu color, has hidden itself in 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 becomes of the cotyledons. Tho germination of the tulip-tree, oak, pea, squash, and other Dicotyledons maybe watched with equal advantage, and the chief differenco observed among them will be in the disposal of the cotyledons. In general, these arise with the ascending axis, as in the mnple and bean, and act as the first pair of leaves; but some- times, when they are very thick, as in the pea, . buck-eve. oak (6â9), tliev remain as first Germination of Wheat; o, the grain , . , , â ,o i â , a\ -^ a â¦ontainin* the cotyledon ; c, plumule; r, P^ced wlth the ~Uum (§ 118)> neither ascend- Mdiole; «, rooUets (adventitious). ing nor Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Wood, Alphonso, 1810-1881.
