Regularity: Regularly occurring
Global Range: Oahu, Molokai, Lanai, Kahoolawe, Maui, Hawaii
The inclusion of Oahu in the range of this species appears to be based on misidentified specimens. (J. Lau, 2003)
Comments: Found in a variety of communities in dry, exposed areas. Woodlands communities include those dominated by Metrosideros polymorpha or Chamaesyce olowaluana. Shrubland communities include 'A'ali'i (Dodonaea) Montane Dry Shrubland, an open shrubland with a ground cover of grasses and herbs and rare/scattered trees throughout its upper range, as well as other open to dense shrublands of Dodonaea viscosa, Myoporum sandwicensis, Sophora chrysophylla, Styphelia tameiameiae, and Chenopodium oahuense. It can be a dominant species in native grassland communities, including Lovegrass/Mountain Pili (Eragrostis/Panicum) Montane Dry Grassland, which has a dense grass cover with scattered shrubs. 120-1920 m, most abundant above 1220 m.

Not common on Molokai, Lanai, Kahoolawe, and Maui. Common on a portion of Hawaii Island (southwestern Maunakea and adjacent areas in the saddle between Maunakea and Maunaloa), but apparently absent from most other parts of the island.
