| It consists of one or more seed-leaves or cotyledons, a radicle or young root, and a plumule or young bud. |
| Plumage generally compact, the feathers with thick spongy shaft, and destitute of plumule. |
| So it is the stem-portion of the plumule which is at first conspicuous and strong-growing. |
| It is important that the leaves on the primary axis arising from the plumule are examined. |
| Correspondingly, the young leaves of the plumule in such plants as the bean do not expand and become green except after exposure to light. |
