Lobe (leaf)
[ Botany ] |
 A
leaf lobe is a partial rounded portion of a
leaf
margin, separated from the whole by a more or less deeply
indentation (sinus)
that does not break the continuity of the structure (deeper than the
ones it may have if it is toothed (serrate)
but less than halfway to the
midrib) Lobes only at the base of
the leaf do not count.
Lobe vs. tooth: It is not clear what is the
difference between teeth and lobes; a general but not exhaustive
definition is: “ Lobes are marginal indentations that reach ¼ or
more of the distance to the midvein, measured parallel to the
axis of symmetry of the lobe, tooth are less than ¼”. |
