east central Kauai, 500-750 m elevation. Hardy's loulu is found from wet to very wet forests below and east of Waiʻaleʻale to just south of Līhuʻe side in eastern Kauaʻi in the Līhuʻe-Kōloa, and probably Keālia, Forest Reserves from 1600 to 2300 feet in elevation. ("Loulu: The Hawaiian Palm", pages 1, 86, 90, 91.)


To 10 m tall; proximal margins of petiole with only a few fibers; leaf blade flat, divided 1/2, abaxial surface completely covered with lepidia and appearing silvery grayish white, segment lips stiff; inflorescences composed of 2-5 panicles, equaling or exceeding leaf blades in flower, greatly exceeding leaf biades in fruit, panicles branched to 2 or 3 orders, rachillae clothed with dense, felt-iike indumentum or glabrous; fruits 20-35 x 15-16 mm, ellipsoid to obovoid.

Pritchardia hardyi is distinctive in its leaf blades completely covered abaxially with lepidia, inflorescences equaling to exceeding the leaf blades in flowers and exceeding them in fruit, and small fruits. It is similar to P. viscosa but the latter differs in its viscous panicles and inflorescences shorter than the petioles. The photograph of P. hardyi in Beccari and Rock (1921, PI. XlII A) actually depicts P. waialealeana. (


Comments and Curiosities

Etymology: Pritchardia name is dedicated to William Thomas Pritchard (1829-1907), British official stationed in Fiji in the 19th Century, British counsul in Fiji, adventurer, and author of Polynesian Reminiscences in 1866. The specific epithet hardyi is named for W. H. Hardy. ("Loulu: The Hawaiian Palm", pages 1, 86, 90, 91.)

Conservation: Critically Endangered, Found along the Powerline Trail on Kauai Island. Only 30 individuals are known in the wild and regeneration is limited. (ICUN Redlist 1998.)

A smaller species from wet forest on Kauai that reaches a height of about 6 m (20 ft.), with a slender trunk to 20 cm (8 in.) in diameter. The rigid leaves have silvery undersides and the leafbases have curious, upright fibers. Seeds are oblong. (
