Scalesia
Species
microcephala
Taxon category: Accepted
Taxon origin: Endemic
Distribution: This species has two varieties on Fernandina and North Isabela Islands. The population has declined on Isabela, especially on the Alcedo volcano, due to feral animals, but is possibly stable today, due to the eradication program. Its recovery depends on the success of this program.
