There is only one species of loulu endemic to the Island of Lanai:
Pritchardia glabrata, Kahanu Garden, Honomaele, Hana, Maui
Pritchardia glabrata. Prior to December, 2007, the species native to this island was called Pritchardia lanaiensis, after the habitat, but in his latest review of the genus Pritchardia, Don Hodel found that the Lanai native was really Pritchardia glabrata, which is also native to the west end of the Island of Maui. The presentation on this species was included in the Chapter on the Island of Maui. Lanai is the third and last island comprising the County of Maui to be presented. The Island of Kaho’olawe is not known to have any loulu population. I have found no written accounts of whether or not there were any loulu there that are now extinct.
