Discussion

  • Pritchardia forbesiana, one of four Hawaiian species that is recorded from more than one island, is distinguished by its petiole margins with an abundance of conspicuous fibers proximally, leaf blades incompletely covered abaxially with lepidia and with drooping segment tips, inflorescences shorter than or equaling the petioles, and large fruits. On Molokai P. forbesiana occurs with or near P. lowreyana but the latter differs in its longer inflorescences that in fruit equal the leaf blade. (Hodel, D. 2007. A Review of the Genus Pritchardia. Palms 51(4): Special Supplement S 1-53.)A

Description

  • To 10 m tall; proximal margins of petiole with abundant fibers; leaf blade undulate, divided 1/3, abaxial surface incompletely covered with scattered lepidia, segment tips stiff to drooping; inflorescences composed of 1-4 panicles, shorter than to equaling petioles in flower and fruit, panicles branched to 2 orders, rachillae glabrous to clothed with scurfy indumentum in flower, glabrous in fruit; fruits 40-45 x 32-35 mm, ellipsoid.
