%X We document the naturalization of the New World Helianthus debilis Nuttall subsp. cucumerifolius (Torrey & A. Gray) Heiser in central Taiwan. A taxonomic treatment, line drawings, and color photographs of this species from the wild are provided to aid in identification. This represents the first report of Helianthus species in Taiwan. The colony of H. debilis subsp. cucumerifolius was first observed in Taiwan in 1999. During our field survey in 2007 we witnessed the significant range expansion though the coast of Changhua County. The potential of H. debilis subsp. cucumerifolius to become an invasive species in Taiwan is worthy of attention.
