Cycas is a genus of cycad, and the only genus in the family Cycadaceae. About 113 species are accepted, which are native to the Indo-Pacific, East Africa and Madagascar.

Callitris baileyi is a species of conifer in the family Cupressaceae. It is found only in Australia, more specifically Southeast Queensland. Its common English name is Bailey's cypress-pine. The name is dedicated to Australian botanist Frederick Manson Bailey, who was the first to collect specimens of this tree. Bailey's name is closely associated with much of the flora of Queensland and their elucidation in Southeastern Queensland. Over the past few decades the conifer has been severely threatened by habitat loss Fruiting for the species has been recorded year-round.
Cycas micronesica is a species of cycad found on the island of Yap in Micronesia, the Marianas islands 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 in 1994 by Ken Hill. Paleoecological studies have determined that C. micronesica has been present on the island of Guam for about 9,000 years. It is linked with Lytico-Bodig disease, a condition similar to amyotrophic lateral sclerosis (ALS), due to the neurotoxin BMAA found in its seeds, which were a traditional food source on Guam until the 1960s. The neurotoxin is present due to its symbiosis with cyanobacteria.
