Prunus serrulata or Japanese cherry is a species of cherry tree that grows naturally in Japan, China, Korea, and Vietnam, and it also refers to a cultivar produced from Prunus speciosa, a cherry tree endemic in Japan. Historically, the Japanese have developed many cultivars by selective breeding of cherry trees, which are produced by the complicated crossing of several wild species, and they are used for ornamental purposes all over the world. Of these, the cultivars produced by complex interspecific hybrids based on the Oshima cherry are also known as the Cerasus Sato-zakura Group.

Cycas micronesica is a species of cycad found on the island of Yap in Micronesia, the Marianaislands of Guam and Rota, and The Republic of Palau. It is commonly known as federico nut or fadang in Chamorro. The species, previously lumped with Cycas rumphii and Cycas circinalis, was described as a unique species in 1994 by Ken Hill. Paleoecological studies have determined that Cycas micronesica has been present on the island of Guam for about 9,000 years. It has been implicated as a factor in Lytico-Bodig disease, a condition similar to amyotrophic lateral sclerosis (ALS), due to the presence of the neurotoxin BMAA found in its seeds. Seeds were a traditional food source on Guam until the 1960s. The neurotoxin is present due to a symbiosis with cyanobacteria.
