Pritchardia sp. Loulu are the native Hawaiian palm trees. Fossil evidence suggests loulu were once a dominant tree in lower elevation forests, but they're fairly sparse today in remnant native forests. Pigs and rodents love to eat their fleshy nuts. The fruit of the loulu is called "hawane", and there was once a colorful little palmcreeper bird that lived in the loulu called the 'ula 'ai hawane , which is long extinct.

The four native species of Hawai'i island are p. beccariana (most of the photos below), p. lanigeri, p. affinis and p. schattaueri. The last two are endangered, and the latter was down to a handful of individuals. There are also imported pritchardia from other islands, and from Fiji. Loulu are used extensively in landscaping.
