Comment
A lemma (PO:0009037) and palea (PO:0009038) enclose an individual spikelet floret (PO:0009082). The lemma is usually the larger of the two. Since it is not clear what the lemma and palea correspond to in conventional flowers, no assumptions of homology are made. If you are annotating to this structure for Zea species an annotation can also be made to the more specific floret type, if known. Choose the most specific term possible from: ear floret (PO:0006354), lower floret of pedicellate spikelet of ear (PO:0006353), lower floret of sessile spikelet of ear (PO:0006351), upper floret of pedicellate spikelet of ear (PO:0006350), upper floret of sessile spikelet of ear (PO:0006352), tassel floret (PO:0006310), lower floret of pedicellate spikelet of tassel (PO:0006313), lower floret of sessile spikelet of tassel (PO:0006315), upper floret of pedicellate spikelet of tassel (PO:0006314), upper floret of sessile spikelet of tassel (PO:0006316). Found in Found in Poaceae, Cyperaceae and other Poales.
