Cycas micronesica is a type of cycad found in Micronesia , the Marianas Group and the western Caroline Islands. The species, previously lumped with Cycas rumphii or Cycas circinalis, was described in 1994 by Ken Hill.[2] It is linked with the human degenerative disease Lytico-Bodig disease, which is similar to amyotrophic lateral sclerosis (ALS) through a neurotoxin in the seeds, which were a traditional food source on Guam until the 1960s.[3]

Conservation

Cycas micronesica is threatened by an introduced insect pest, the diaspidid scale Aulocapsis yasumatsui, first recognised in Guam in December 2003.[4] Because of this the species is considered to be endangered.[1]
