• Label: Leaf area
• Entity URI: https://w3id.org/APD/traits/trait_0011211
• Type: numeric
• Definition: A leaf area trait [TO:0000540] which is the 2-D [PATO:0001709] area [PATO:0001323] of the leaf lamina [PO:0020039] and petiole [PO:0020038]. For some species the area of a leaf analogue is reported, possibly a leaflet [PO:0020049], cladode [PO:0025354], or phyllode [PO:0025335].;The 2-dimensional projected (scanned) area of the surface of a leaf or a leaf analogue (leaflet, cladode, phyllode).
• Additional comments: This trait includes measurements of leaves and leaf analogues, including leaflets, cladodes, and phyllodes. When a measurement is made on a leaf analogue, the tissue measured should be documented as part of the methods or noted as a `context` or under `measurement_remarks`. Leaflet area can alternatively be mapped to the trait `leaflet_area`. It is most common for leaf area measurements to include the petiole; the measurement methods should indicate if the petiole is included in or excluded from the leaf area measurements. For terete leaves, leaf area should still be recorded as the 2-dimensional projected area.
• units: mm2
• allowable range: 0.1 - 10000000 mm2
