Viscid disc adhesive of pollinaria of the orchid, Catasetum , was analyzed for sugars and amino acids by TLC. Sucrose, glucose, and fructose are predominant; two other unidentified aldoses are present. Glucosamine, or one of its derivatives, apparently also is present. Glycine and serine predominate in the protein hydrolysate, and glutamate and aspartate are in high content. The adhesive appears to be a glycoprotein.
