• Label: Leaf divisions
• Entity URI: https://w3id.org/APD/traits/trait_0011317
• Type: categorical
• Definition: A leaf shape trait [TO:0000492] which indicates types [NCIT:C25284] of lobed leaves [PO:0025517] and compound leaves [PO:0020043], including the arrangement [NCIT:C61532] of the lobes or leaflets [PO:0020049] with respect to the midrib [PO:0020139] or other primary leaf veins [PO:0025413] and the number of orders of axes [NCIT:C25154] across which there are incisions or divisions.;A trait that captures the types of lobed leaves and compound leaves, including the arrangement of the lobes or leaflets relative to the midrib or other primary veins and the number of orders of axes across which there are incisions or divisions.
• Additional comments: This trait provides detailed description of leaf divisions, beyond what is captured in `leaf_compoundness` (simple versus compound) and `leaf_lobation` (entire versus lobed). The term 'divided' is meant to indicate lobing, such as "trichotomously divided", but as 'divided' is also used in some context to indicate the divisions of leaves into leaflets, it is avoided as a trait value for this trait.
• Allowed values:

  value	description
  bipartite	Leaf divided into two lobes.
  bipinnate	Leaf that is twice pinnate, having pinnate leaflets that are themselves pinnately divided.
  bipinnatifid	Leaf that is twice pinnatifid, with two series of lobes that extend less than half-way to the midrib.
  bipinnatipartite	Leaf that is twice pinnatipartite, with two series of lobes that extend more than half-way to the midrib.
  bipinnatisect	Leaf that is twice pinnatisect, with two series of lobes that extend nearly to the midrib but the divisions are not separated into distinct leaflets.
  dichotomously_lobed	Leaf divided repeatedly into two lobes.
  palmately_compound	Leaf divided into leaflets that attach to a central point. (Synonyms, digitate)
  palmately_lobed	Leaf with divisions that radiate from a single point, usually the basal junction of major veins.
  pinnately_compound	Leaf divided into leaflets that attach along a central axis. [PATO_0000410]
  pinnately_lobed	Leaf with divisions that are symmetrical across a central axis, usually the midvein.
  pinnatifid	Leaf with lobes that extend less than half-way to the midrib.
  pinnatipartite	Leaf with lobes that extend more than half-way to the midrib.
  pinnatisect	Leaf with lobes that extend nearly to the midrib but the divisions are not separated into distinct leaflets.
  trichotomously_lobed	Leaf divided repeatedly into three lobes.
  trifoliate	Leaf divided into three leaflets. (Synonyms, ternate, trifoliolate)
  tripartite	Leaf divided into three lobes.
  tripinnate	Leaf that is three times pinnate, with pinnate leaflets that are twice more pinnately divided.
