Hibiscus tiliaceus was probably introduced to Hawaii by Polynesians (prior to Western contact).  "I don't know of any solid evidence that Hibiscus tiliaceus was here in the pre-human period. On the contrary, David Burney (pers. comm.) says that there is no pollen of it in estuarine deposits on Kauai until after the time when humans are posited to have arrived. Being that it is quite frequent on marsh edges and in lowland streamsides, I would be surprised not to see some pollen if it were here. In addition, either Frank Howarth or Dan Polhemus told me that there are no endemic insects that specialize on it, which is surprising since virtually all relatively common native species have at least some specialist insects. Together, I take these independent tidbits as circumstantial evidence that Hibiscus tiliaceus was a Polynesian introduction. I think more work. perhaps genetic in nature, might add more to the story." (Jon Price, pers. comm. [e-mail to pt@hear.org], 27APR2006)

"It is not possible to ascertain whether this species is indigenous or a Polynesian introduction; however, since it is easily dispersed by drifting in seawater and as the seeds are viable for several months, it may have arrived in Hawaii via water dispersal." (Wagner et al. 1999. Manual of Flowering Plants of Hawaii [rev. ed.]. p. 888)
