English: The distribution of Cneoridium dumosum, a monotypic genus in the Citrus family, within North America. Centered on northern Baja California. Dashed areas indicate regions of likely distribution, while opaque green areas indicate regions where the plant is known to occur with reference to herbarium records. Question marks indicate potential areas of distribution in the large gaps between herbarium records in sparsely-botanized areas.
