Habitat and Distribution

Hawaii. Wet forest in the Kohala Mountains, northern and eastern slopes of Mauna Kea,

and on the southeastern slope of Mauna Loa, Hawaii, SOG-1400 m elevation. Woolly loulu has an unusual, disjunct distribution at opposite ends of Hawaiʻi Island. In the north and northwest, it occurs in the Kohala Mountains and extends partway around the northern slope of Mauna Kea to its eastern flank; in the south it is found on the southeastern flank of Mauna Loa in Kaʻū. This species is found in very wet forest on mostly flat to gently sloping terrain from 1500 to 4300 feet. ("Loulu: The Hawaiian Palm", pages 1, 104, 105.)


To 15 m tall; proximal margins of petiole with moderate fibers; leaf blade slightly undulate to nearly flat, divided 2/5-1/2, abaxial surface incompleteiy covered with scattered iepidia, segment tips stiff; inflorescences composed of 1-3 panicles, equaling or exceeding petioles in flower, exceeding petioles but shorter than leaf blades in fruit, panicles branched to 2 orders, rachiUae permanently clothed with dense, reddish brown, cottony or woolly indumentum; fruits 35-55 x 30-40 mm, globose to ellipsoid.

Pritchardia lanigera is distinguished by its leaf blades incompletely covered abaxially with lepidia, inflorescences equaling or exceeding the petioles in flower and exceeding the petioles but shorter than the leaf blades in fruit, and the rachillae permanently clothed in cottony to woolly indumentum. It is similar to P. woodii but the latter differs in its rachillae clothed with felt-like rather than cottony or woolly indumentum. Although Beccari (1890) and Beccari and Rock (1921) stated that Lydgate collected the type, photographs at FI of the destroyed holotype at B show it to have only Hillebrand's name on it. Lydgate frequently collected for or with Hillebrand, though, and it is likely that Hillebrand, who sent his original set of specimens to B, would have put his own name on specimens even if Lydgate had collected them.
