• Additional comments: For terms pertaining to 2-dimensional leaf lamina divisions and incisions that are less than 1/8 of the distance to the midrib, see the trait `leaf_margin`. See also the trait `leaf_division` for more detailed leaf lobation (and leaf compoundness) trait values. Note that there might be some species that grade from deeply lobed simple leaves to compound leaves.
• Allowed values:

  value	description
  lobed	Leaf margin has incisions, either rounded or sharp-tipped, that extend more than 1/8 of the distance to the midrib.
  lobed_deep	Leaf margin with lobes that extend more than halfway to the midrib. (Synonyms, parted, divided)
