Scientific Name: Phyllostegia mollis
Species Authority: Benth.
Taxonomic Notes: Information from NatureServe (2003): "Phyllostegia mollis is a generally recognized endemic Hawaiian species, treated as multi-island by Wagner et al. (Manual, 1990) and USFWS (1991), but treated as an O`ahu endemic by Wagner and Herbst (Supplement, 1999). The Moloka'i and Maui plants formerly included in P. mollis were recognized by Wagner and Herbst (1999) as under the name P. haleakalae, and later by Wagner (Novon 9: 274-275, 1999) as P. pilosa, with the name P. haleakalae being considered instead an older name for the species generally known as P. imminuta".
