12 years ago Lobes can be either rounded or pointed, and are defined based on the size of the projection.
Teeth' are pointed projections that extend less than 1/4 of the way to the midline.
Crenae (sing. crena) are small rounded pointed projections that extend less than 1/4 of the way to the midline.
Revised proposed definitions:
ref: JSTOR:2441319 (Hickey 1973)
phyllome lamina lobe: A cardinal organ part (PO:0025001) that is a projection on a phyllome margin (PO:0025018) for which the corresponding phyllome sinus (PO:0025383) extends one quarter or more of the distance to the center of the long axis of the phyllome lamina (PO:0025396).
Comment: A phyllome lobe may be either rounded or angular at the tip, and may have phyllome teeth (PO:id) or phyllome crenae (PO:id) on its margin. The corresponding phyllome sinus may be rounded or angular. part_of phyllome lamina (rather than part of lamina margin, because they lobe includes all of the tissue inside the margin).
leaf lamina lobe: A phyllome lobe (PO:id) that is a projection on a leaf lamina margin (PO:0025009) for which the corresponding leaf sinus (PO:0025384) extends one quarter or more of the distance to the center of the long axis of the leaf lamina (PO:0020039).
Comment: A leaf lobe may be either rounded or angular at the tip, and may have leaf teeth (PO:id) or leaf crenae (PO:id) on its margin. The corresponding leaf sinus may be rounded or angular. part_of leaf lamina
phyllome lamina tooth: A cardinal organ part (PO:0025001) that is an angular projection on a phyllome margin (PO:0025018) for which the corresponding phyllome sinus (PO:0025383) extends less than one quarter of the distance to the center of the long axis of the phyllome lamina (PO:0025396).
Comment: See phyllome lamina crena (PO:id) for a small rounded projection. The corresponding phyllome sinus may be rounded or angular. part_of phyllome lamina
leaf lamina tooth: A phyllome lamina tooth (PO:id) that is an angular projection on a leaf margin (PO:0020128) for which the corresponding leaf sinus (PO:0025384) extends less than one quarter of the distance to the center of the long axis of the leaf lamina (PO:0020039).
Comment: See leaf lamina crena (PO:id) for a small rounded projection. The corresponding leaf sinus may be rounded or angular. part_of leaf lamina
Add "teeth" as exact plural synonym to all. Other synonyms from FNA.

At the POC meeting on 1-10-12, we added the term "sinus" and agreed to add the related terms for tooth and lobe, all part_of margin.
We currently have organ margin (PO:0025005) and phyllome margin (PO:0025018) without part_of relations. Suggest that we add organ margin is part_of lamina, phyllome margin part_of phyllome lamina.
Leaf margin (PO:0020128) is already part of leaf and leaf lamina margin (PO:0025009) is part_of leaf lamina.
'''proposed definition, lobe:''' A cardinal organ part that is a rounded projection on the margin of an organ. part_of organ margin
'''proposed definition, phyllom lobe:''' A lobe that is a rounded projection on the margin of a phyllome. part_of leaf phyllome margin
'''proposed definition, leaf lamina lobe:''' A phyllome lobe that is a rounded projection on the margin of a leaf lamina. (Is this in vascular leaf only?) part_of leaf lamina margin
Can add other types of lobes as we want, or wait until they are requested.
'''proposed definition, plant organ tooth:''' A cardinal organ part that is a pointed projection on the margin of an organ. part_of organ margin
'''proposed definition, phyllome tooth:''' A plant organ tooth that is a pointed projection on the margin of a phyllome. part_of leaf phyllome margin
'''proposed definition, leaf lamina tooth:''' A phyllome tooth that is a rounded projection on the margin of a leaf lamina. (Is this in vascular leaf only?) part_of leaf lamina margin
Can add other types of teeth as we want, or wait until they are requested.
Be sure to add "teeth" as exact plural synonym to all.
