Cycad
Cycas micronesica K.D.Hill
Cycas micronesica is a cycad species native to Micronesia, the Mariana Islands, and Palau. It was described as a distinct species in 1994 by Ken Hill. The plant has a long history on Guam, with evidence of its presence dating back 9,000 years. Its seeds contain the neurotoxin BMAA, which is linked to the disease Lytico-Bodig, a condition similar to ALS. The seeds were traditionally consumed on Guam until the 1960s. The neurotoxin is produced through a symbiotic relationship with cyanobacteria.

The species was once grouped with Cycas rumphii and Cycas circinalis but is now recognized as distinct. It is found in Oceania, including the Caroline Islands, Marianas, and Marshall Islands. The plant's ecological and historical significance is notable, particularly in relation to its role in local health conditions. Its traditional use as a food source and its association with a neurotoxin highlight its complex relationship with human health in the region.
