Habitat and Distribution

Endemic to Hawaii. Moist to wet forests in valleys and on exposed ridges and cliffs,

Koolau Mountains and southern Waianae Mountains, Oahu, 300-800 m elevatIon. Loulu hiwa is endemic to Oʻahu (Koʻolau Mts., southern Waiʻanae Mts.) from about 985 to 2625 feet in wet forest valleys, slopes, exposed ridges, precipices, cliffs, and sometimes into mesic valleys. ("A Review of the Genus Pritchardia", pages S-3, S-8, S-21-22, S-27-32.)

Description

To 10 m tall; proximal margins of petiole with irregularly shaped, papery ligules or wings or only a few (to rarely moderate) fibers; leaf blade slightly undulate to nearly flat, divided 1/4-1/2, abaxial surface completely covered with lepidia and appearing silvery grayish white to sometimes tinged with brown, segment tips stiff; inflorescences composed of 1-4 panicles, shorter than petioles in flower and fruit to exceeding petioles or leaf blades in flower and greatly exceeding leaf blades in fruit, panicles branched to 2 orders, rachillae clothed with dense, felt-like indumentum or glabrous; fruits 40-50 x 25-40 mm, eiiipsoid to globose to ovoid.

Pritchardia martii can be distinguished by its petioles with irregularly shaped, papery ligules or wings or only a few fibers proximaiiy; leaf blades completeiy covered abaxiaiiy with lepidia; rachiiiae glabrous or with felt-like indumentum; and large fruits. Pritchardia arecina is similar but differs in its petioles with an abundance fibers proximaiiy. Although poorly documented, the identities of Pritchardia martii and P. gaudichaudii are, nonetheless, inextricably linked and critical to establishing taxonomic and nomenclatural order among the Hawaiian taxa, because they are the oldest names in the genus. Gaudichaud coiiected the original material of both during the voyage of the Bonite in Hawaii in October, 1836.
