Origin: in Lawai Valley, Kalaheo, Kauai, Hawaii, on the Deschwanden orchard, operated by A. Glaisyer, Jr. Introd. in 1967. Unknown seedling; selected in 1948; 1953 testing began by the Univ. of Hawaii at Poamoho Expt. Farm, Oahu, and Makawao Expt. Farm, Maui; first grafted trees fruited in 1958; tested as HAES 660. Nut: size medium, averaging about 80 nuts/lb, about 0.9 inch in diam.; shell smooth, medium brown with variable amounts of lighter speckling; kernel 42% to 46% of nut, color light cream; harvest August-November. Tree: moderately vigorous, with well-formed ascending branch structure so that the tree does not take up as much space as more-spreading varieties; strong, medium-wide crotch angles; productive, kernel yield greater than Keauhou, Ikaika, and Kakea in replicated field testing over a 4 years; not as tolerant to anthracnose as Keauhou, but superior in tolerance to Ikaika or Kakea. Named after Keaau Orchard of the Royal Hawaiian Macadamia Nut Co., near Hilo, Hawaii, where the first comprehensive yield test was conducted. Fruit:
