Lersten, H. Horner] Calcium oxalate crystal types and distribution within leaves ofPrunus sensu lato (Rosaceae; Prunoideae) were surveyed from mostly herbarium specimens (196 specimens of 131 species of all five subgenera usually recognized). Rehydrated samples were bleached, mounted unstained, and viewed microscopically between crossed polarizers. Six patterns were recognized based on crystal type and relative distribution around veins and in mesophyll. Druses predominate in four subgenera, but prismatics are most common in subgenus Padus. Prunophora and Amygdalus, considered to be the most advanced subgenera, have virtually only druses, which are almost always associated with veins. Cerasus and Laurocerasus, intermediate subgenera, have the greatest diversity of patterns, but few species with prismatics. A trend is evident from mostly mesophyll prismatics in Padus to fewer prismatics and more druses of mixed distribution in Laurocerasus and Cerasus, to mostly druses restricted to veins in Amygdalus and Prunophora.
