Fig. 6.4-1.
Longitudinal section of axillary bud of coleus (Coleus). This is young
axillary bud definitely has two leaf primordia (LP): we can see them attached to
the bud apical meristem. But notice the arc of red-stained material above the
bud; that is a young, growing leaf that was probably attached to this axillary
bud along either the front or back, but microtoming cut away the attachment
region. The leaf was curved, such that it arched over the bud, so the microtome
knife caught this bit of it.
