Definition
A phyllome lamina (PO:0025396) that is the part of a leaf (PO:0025034) exclusive of the petiole (PO:0020038) or leaf sheath (PO:0020104), if either is present. Source: POC:curators
Comment
A leaf lamina is usually dorsiventrally flattened, but may be flattened in a median plant (perpendicular to the axis) in the case of phyllodes (PO:0025335) or other ensiform leaves (PO:0025333). This term should not be used for leaves that are not laminar (flat), like round leaves in Allium or needle-like leaves in Pinus or some Proteaceae. If you are annotating to this term, please add an additional annotation to vascular leaf (PO:0009025) or non-vascular leaf (PO:0025075), depending on the species. All annotations for angiosperms, gymnosperms, and pteridophytes should go to vascular leaf and all annotations for bryophytes should go to non-vascular leaf.
