Fig. 1. Lemma and palea organs covering developing kernels of Morex barley. Left, lemma completely covers abaxial surface of kernel. The awn is continuous with the lemma. Center, palea covers most of the adaxial surface and is partially covered by the lemma. Ovary epithelial hairs (OEH) protrude above the palea tip. Right, lemma and palea teased apart from the developing kernel exposing the pericarp.
